How to Properly Calibrate Dell U2413 / U2713H / U3014 Monitors

After we published our article on 10 bit per channel workflow, our readers requested to provide information on how to calibrate monitors with a built-in Look-Up Table (LUT). Specifically, a number of our readers asked to provide a detailed guide on how to properly calibrate the Dell U2413, U2713H and U3014 monitors, which we have recommended a number of times before due to their affordable price, attractive features and superb color reproduction for photography needs. Historically, true 10-bit and higher monitors with hardware LUT capabilities were extremely expensive, making them only attractive to those with large budgets. With the introduction of sub-$500 monitors featuring professional-grade IPS panels (read our article on best monitors for photography to understand IPS terminology), those with tighter budgets are now seriously considering such monitors for photography work. Unfortunately, many end up even more confused after acquiring such tools due to questions related to proper monitor calibration.

Dell U2413

1) Software vs Hardware Calibration

There are two types of calibrations available for monitors – software and hardware. Software calibration works by modifying the colors via the computer graphics card and loading those colors every time the operating system boots. Software calibration is usually performed on monitors that do not have the LUT capability (very few do). Thus, most monitors on the market today would be calibrated via software. During the calibration process, calibration software will usually ask to adjust brightness, contrast and color levels on the monitor, if such options are available.

Hardware calibration, on the other hand, generates a Look Up Table that is written into the monitor to map all the colors. Brightness, contrast and color levels are automatically adjusted by the monitor through calibration software. Compared to software, hardware calibration is much more accurate and there is no need to modify color output through the graphics card. Depending on the monitor type / model, several combinations of color calibration are possible. With the Dell U2413, for example, one can calibrate two separate user-selectable preset modes: CAL1 and CAL2. This allows calibrating the U2413 for several color spaces such as AdobeRGB and sRGB. Please note that the factory-calibrated AdobeRGB and sRGB profiles are different and might not be as accurate, especially after several months of use.

2) Calibration Hardware and Software

The Dell U2413 / U2713H and U3014 monitors have a very specific process for hardware calibration using the LUT. They require the X-Rite i1 Display Pro hardware and specific Dell UltraSharp Color Calibration software. Unfortunately, you cannot use any other hardware or software for true hardware LUT calibration. Even using X-Rite’s calibration software will not work, only giving you options for software calibration, since only the Dell calibration software contains specific drivers for these Dell monitors.

Once you get the X-Rite i1 Display Pro Colorimeter, it is time to download the Dell UltraSharp Calibration Solution. As of 07/16/2014, the latest version is 1.5.3 and it can be downloaded directly from Dell’s support page. Go ahead and download the software.

3) Software Installation Preparation

Before installing the software, absolutely make sure that you uninstall all existing color calibration software and profiles. If you have previously installed X-Rite’s calibration software, go ahead and uninstall it completely and reboot the computer. Next, open up “Color Management” in Control Panel and make sure to get rid of all existing color profiles that you have previously created. When the window opens up, check “Use my settings for this device”, then select every ICC profile and click the “Remove” button:

Windows Color Management Remove Profiles

Make sure to do this for every monitor you have. Once you get to the last profile, your computer will complain that the color profile is default. Click “Continue” and delete the default profile as well. After you delete all profiles, reboot the computer one more time.

After the computer is rebooted, go back to Color Management and make sure that all custom profiles are deleted under the “All Profiles” tab. Do not delete any of the default ICC profiles – only delete the ones that you specifically created for your monitor(s) before.

4) Software Installation

Now that your system is clean, go ahead and install the Dell UltraSharp Calibration Solution. The process is pretty self-explanatory – just click Next until the software starts installing. Once the installation is complete, you should have a monitor icon on your desktop that says “Dell UltraSharp Calibration Solution”. Go ahead and double click it to start the calibration software.

5) Reset to Factory Defaults

At this point, you should reset your monitor to factory default settings. This will wipe out existing LUT data and return the monitor to the “clean” state for proper calibration. Resetting to factory defaults is easy – press the navigation button on the side of the monitor, then go to Menu -> Other Settings -> Factory Reset. Only start the calibration process after all monitors are fully reset.

6) Hardware LUT Calibration Process

Before starting the calibration process, you will have to decide what “RGB primary”, or color space to emulate. The software will give you the following options:

  1. AdobeRGB
  2. sRGB
  3. Rec. 601
  4. DCI-P3 Emulation
  5. SMPTE-C
  6. Native

Out of all the modes listed above, the “Native” mode will give you the most number of colors, so I would recommend to start with that one. Both AdobeRGB and sRGB will limit the color space to a smaller number, with sRGB stripping out most of the color gamut. Therefore, my recommendation would be to calibrate the “CAL 1″ preset to “Native” color space for the most colors and “CAL 2″ to “sRGB”. This way, you would normally be looking at the most number of colors in “CAL 1″ Preset and if you need to fall back to less colors for images that you are publishing to the web or perhaps printing in sRGB color space, you could change to “CAL 2″ Preset. If you do a lot of printing and your printer / printing company can work with AdobeRGB color space, then set “CAL 2″ to AdobeRGB instead. Basically, set up these color profiles to color space you will be using the most. Personally, I set up mine to “Native” and “sRGB”, with “Native” staying as default preset most of the time.

When the software launches, you will be presented with the home screen that has a number of options to the left of the screen such as “Display Profiling”, “Projector Profiling”, “Printer Profiling” and “Scanner Profiling”. Go ahead and click on “Display Profiling”. On the next page, you will be presented with Display Settings. This screen will show the RGB Primary referenced above and the Luminance level. Go ahead and pick “Native” and “120 cd/m2“.

Dell UltraSharp Calibration Solution Display Settings

Click Next and you will be presented with the “Measurement” screen. Make sure to pick “Calibration 1″ and now do the same on your monitor by going to Preset Modes -> Color Space -> CAL 1. Once there, click the “Start Measurement” button:

Dell UltraSharp Calibration Solution Measurement

Now the software will ask you to hang the colorimeter on the center of the monitor to start the calibration process. First, the software will determine the brightness and contrast levels and after that, it will start measuring all the colors. The whole process will take between 5 to 10 minutes to complete. Once the calibration is complete, you will be presented with a screen to save the profile name. I saved mine as “DELL U2413 (Left).icm” for the left screen and “DELL U2413 (Right).icm” for the right screen.

Please note that the current version of Dell UltraSharp Calibration Solution has a problem when calibrating the second screen – the software might not recognize the LUT hardware. If you do not see the above-mentioned color spaces and if the “Selected calibration matrix” is not “RG Phosphor / GB-LED”, then you will have to run calibration through a workaround until Dell addresses the issue in the next release. The workaround is simple – all you have to do is turn off the primary display, close the software and relaunch it. In single monitor mode, the software will recognize the hardware and let you calibrate the screen. After calibration is finished, turn the primary display back on and you will be good to go.

If you want to set up CAL 2 for sRGB, repeat the same process, except this time change the “RGB primary” setting to sRGB. Make sure to pick CAL 2 on your monitor before you start the calibration process, or you will end up overwriting the CAL 1 preset.

That’s really it as far as calibration is concerned! Please let me know if you have any questions!

NOTE: This guide can also be used to calibrate the new Dell 4K monitors: UP2414Q and UP3214Q.

    • July 16, 2014 at 11:00 am

      Sergey, that’s a very sweet panel you have there! True 10-bit + LUT should give you plenty of possibilities for a beautifully calibrated setup. When you say no proper soft, isn’t X-Rite or Spyder capable of doing hardware calibration? What about dispcalGUI – does that work for hardware LUT?

        I have x-rite i1 display pro – and it does not give a choice where to store the result of calibration. It create the *.icc file and as I understand it managed by OS only :(
        I tested the Argyll, but long time ago – and as I remember it do the same.
        Or I miss something and don’t know how to do that.

          Sergey, take a look at the “Measurement” screen during the calibration. If it says “RG Phosphor / GB-LED” with ADC grayed out, then it is hardware calibration. If it gives you options for Gamma corrections and other profiles, then it is software calibration. With software calibration, the generated ICC profile will contain all the colors. With hardware calibration, the generated ICC profile is very small – all colors are stored on the monitor LUT.

          • Sergey Nikitin
            July 17, 2014 at 5:18 am

            I have ADC enabled. And I can cheсk it on or off. But I don’t really understand what kind of “color -technology” – CCFL with wide gamut, RGB-LED, Native or something else – I will try different of them and I can’t see difference…
            (sorry, but iProfiler not able to switch language – in my installation it always show in russian-locale and I can find out – where to change it to English to show you proper screenshot)

            And so, I think the ADC works only for adjusting color, brightness and so on, but not for storing in monitor LUT?

Hopefully someone will save us from spending a day trying each of the option settings …….and even then, picking the one that looks best may not be the right choice.

    I read your 10-bit per channel workflow article and started thinking about getting one of these monitors, but with 4k monitors becoming cheaper and now with Microsoft, Intel, Samsung and others making a big push for the 4k technology, I was wondering if it would make sense to invest on a 10-bit monitor or wait a bit until prices for 4k displays fall into the same price range and get one of those instead. What would you recommend?


    • July 16, 2014 at 10:56 am

      Gabe, that’s what I thought about too just a couple of months ago. But after looking into 4K monitors, I realized that those are far from being solid at this time. As far as I know, all affordable 4K monitors are simply 2 x 1920 pixel wide stitched screens operating at 60Hz, so there are all kinds of issues when rebooting, switching between full screen applications, etc. A true 4K monitor is not cheap and probably won’t be for a while…

    Thanks, Nasim

    A question. Why was 120 selected for the luminance? There is no standard for luminosity. Does that value remain after calibration? My experience is that images prepared on monitors with a luminance that high tend to print somewhat “underexposed” when sent to commercial printers. Would not a value of 90 to 100 be more suitable?

    Thank you, John

    • July 16, 2014 at 11:04 am

      John, it is a personal preference – anything higher is just too bright for my eyes and anything lower is too dark and can result in calibration issues. 100 should work OK, but I would not push it lower. Yes, the value remains after calibration, as the brightness / contrast levels are automatically adjusted on the monitor by the calibration software.

    So, as I understand – when you calibrated you monitor using 8-bit (videocard) LUT – you definitely crop your colors and in that case you cannot see the smooth gradients regardless of have you wide-gamut monitor or not… And moreover – when you open jpeg’s or other files that has embeded color profiles larger then sRGB (for example, I use AdobeRGB workflow) – your soft must proper convert that colors – not into 8bit per color, but something large?
    So, as I observe – all links in the workflow chain must be correct and proper calibrated and produce at the end AdobeRGB RAW/DNG as backup and truncated result in sRGB/device-dependent-CMYK (for web-publishing, printing or any other people with unknown devices). Am I right?

    • July 16, 2014 at 6:05 pm

      Nick, the software says that it is Mac-compatible, so there should be a Mac version of it as well. Are you trying to calibrate one of the above-mentioned monitors? Please note that the hardware and software must match…

    I have the U2713hm screen, anyone out there willing to put up their monitor settings (brightness, contrast,etc)? Also I know that all panels are slightly different, I just need a baseline to go off of. I’m asking because I ordered a print from bayphoto lab and the picture I got was darker than my monitor.

    • July 16, 2014 at 7:20 pm

      Dustin, since your monitor does not have a built-in LUT, you would need to do software calibration via X-Rite or Spyder hardware. I would recommend to start between 100-120 luminance level and go from there. The software will tell you where to adjust the brightness…

    July 16, 2014 at 4:46 pm

    Hi Nasim

    You say that hardware calibration in the monitor is more accurate than software calibration. I don’t understand that. I would think that regardless of where in the chain, from the software to the pixel on the display, the adjustment of luminance values of the different colours are done the result would be pretty much identical. Could you please explain this?

    • July 16, 2014 at 7:18 pm

      Segv, hardware calibration is supposed to be more accurate, because hardware displays better gradation during the calibration process. You can see more info here on Eizo’s website:

    • 10.2) Sergey Nikitin
      July 17, 2014 at 5:00 am

      One of the advantage of the hardware LUT is because it is persistent. On windows the software calibration may be discarded in many cases: You start fullscreen (esp. 3D) games, you change the active monitor (or press Win+P) – and even it may occur if you logout/login… So in manycases the OS (windows) has scheduled task to reload color profile but it will not cover all cases. There is exist reload profile program in But in my case I just create keyboard shortcut to do that
      1. I start XRGamma from XRite : “C:\Program Files (x86)\X-Rite\i1Profiler\XRGamma.exe”

      2. I start the scheduled task to load color profile without invoking UAC dialg:
      So that was slightly complicated
      1. On Press Gx (I use Logitech G510) key I run
      C:\Windows\system32\schtasks.exe /run /TN StartTaskOfColorLoader
      2. Before it I create the task named StartTaskOfColorLoader that run as administrator – and this task start batch file as administrator i.e. without UAC dialog. This task start the C:\MySomeToolsFolder\ReLoadColorProfiles.cmd
      3. This file contains only the line to start windows calibration loader.
      C:\Windows\system32\schtasks.exe /run /TN “\Microsoft\Windows\WindowsColorSystem\Calibration Loader”

      It all because I dont want to switch off UAC and It can’t be change to run “Calibration Loader” task as directly as admnistrator.

      So when I need to reload calibration I press 2 keys on keyboard (In some cases enough to run only Calibration Loader)

      It s crazy but… :(

    July 16, 2014 at 7:12 pm

    Thank you Nasim for your article. It is pretty much everything I’ve learned the hard way the last two weeks since getting my U2413 and the i1. A couple of clarifications please:

    1. Why do you have to delete all the other profiles and uninstall other colorimeter profiles? If they are not the default, why does it matter? For those of us with the Spyder4Pro adjusting our second monitor which is not LUT controlled, what do we do? Will we not need a video card controlled colorimeter? I have the Alienware 2210 LCD.

    2. My Dell software version 1.5.3 does not allow me to do a manual calibration. Instead it wants to do just a ADC calibration like on your example? Why is that? Wouldn’t manual be more accurate?

    3. I think you may have missed the first step. Shouldn’t we return the monitor to factory default settings before starting?

    • July 16, 2014 at 7:31 pm

      Jay, you are most welcome!

      1) I recommend deleting profiles, because you do not want a hardware LUT to be affected by software LUT from the graphics card. With true hardware LUT calibration, there is no software layer. Since a lot of people don’t know how to work well with color management, I recommended to delete all profiles. If you know what you are doing, then it does not apply to you :) For the second monitor, it is safe to keep the old profile, which is generated via software.
      2) What do you mean by “manual calibration”? Do you want to generate a software LUT ICC profile instead of hardware? If yes, then I don’t understand why you would want to do that. You want automated calibration, since it will correctly make all the adjustments to your monitor.
      3) If the CAL 1 and CAL 2 profiles were not touched, then there is no need to reset to factory defaults. However, just to be safe, it is a good idea to do that, so I will add the step to the above guide.

      Thank you!

    Hi Nasim,

    I run a macbook pro and have been using a 2011 thunderbolt display. I gave it to my Dad who was getting very desperate for a monitor upgrade, thinking that Apple would update their monitor soon after the release of the mac pro. Alas, Typical apple, you get no idea whats going on, so in the meantime I’m looking at different monitors.

    I’ve shown a little interest in the new LG 34″ thunderbolt display, and the dell U3014. A quick question please.

    I have the x-rite colormunki display calibration unit. This is not able to run the hardware calibration? I have to have the x-rite i1 display pro to do the hardware calibration?

    It may be a mute point anyway, because I also could not find the software on the Dell site as well.

    I calibrated my U2413 with the i1 and Dell software exactly as in your article. I went native color space with CAL1 and sRGB with CAL2. The native color space is indeed larger than the Adobe RGB. But my reds are really red and flesh tones are really reddish. Is this the extended color range coming out of native? I really like the look on the monitor of Adobe RGB and sRGB better. I did do the new quality check that the Dell software now offers, and both settings passed. So it may be a matter of my eyes adapting and using RAW more instead of possibly exaggerated color space in .jpg files.

    Looks like a good approach. I have the Dell U2413 and have been using the software that came with it for some time. The link you posted for version 1.5.3 is designated for Dell UP2414Q Monitor and the update for the U2413 Monitor on the Dell Support page is a different version. What gives and is this an appropriate version for the U2413 Monitor?

    Good article but some mistakes:

    -No need to factory reset the monitor with Dell Color Calibration Solution 1.5 or higher. It resets LUT3D slot (CAL1/CAL2) when actual calibration starts

    -No need to setup OSD mode in CAL1/CAL2. Just select “Calibration1″/”Calibration 2″ and DCCS 1.5 or higher will select LUT3D slot for you. DCCS may even crash if you start making changed to OSD

    -“Native” is a WRONG choice fro almost any user. It will aim to native white (and max contrast) which is not a daylight white. Is a cyan-green white for most units in GB-LED technology. If you want native gamut select “custom” in DCCS, set your desired white (D65, D55..) and set xy coordinated from EDID data or measured RGB primaries coordinates (both can be obtained with ArgyllCMS/DispcalGUI)

    -No need to remove any profile prior to LUT3D calibration, just select drivers profile (U2413.icm, I hope it was no overwitten in your system) ir order to clean GPU LUT contents modified by some other icm GPU calibration profile.

    @Sergey Nikitin, while Asus PA249Q is a sensible choice since it has not overshoot like dell even if it is not hardware calibratable, the PA279Q is a wrong choice. It has the same faults as U2713H in overshoot artifacts and it is not hardware calibratable.
    As a general rule you need a AMD GOU or nvidia Quadro in order to properly calibrate in GPU a display. Otherwise banding will appear and it will be more painfull with a widegamut display.

    ArgyllCMS/DispcalGUI will not support any kind of hardware LUT3D writing untill ther is a free software library that does that. It’s unlikely that Entech Taiwain will release a fee copy of its libraries. Florian (DispcalGUI creator) has talked several times about it.

    @ Maxim Dupliy, Spyder4 (all flavours including Ellite package) is a lower quality device and it has NO support for GB-LED backlight. DCCS is Xrite software so they will no support a Datacolor device.
    In order to “make it work” the best this lower quality device can do, use your Spyder4 with ArgyllCMS/DisplcalGUI and use Xrite’s spectral corrections (RG_phosphor.edr -> RG_phosphor.ccss) for your GB-LED display.

    @avril Xrite’s software DCCS will work only with i1Displaypro, i1Pro and i1Pro2. It’s a “market” decission from Xrite. So unless you buy or rent some of these units it will not perform a hardware calibration.
    Use “Custom” OSD preset in your U2413 and an AMD or nvidiaQuadro graphics card with ArgyllCMS/DispcalGUI if you want proper GPU calibration.

    • July 23, 2014 at 1:58 am

      Thanks for sharing the tips. The Native profile was recommended by Dell – I guess the person was wrong. Will have to check how “Custom” will impact the whites on my screens. Will report my findings and update the article, if I come to the same conclusion. You are right about everything else. I recommended to remove all profiles, because people might not be able to select the right profile to work with. You don’t want any previously-calibrate profiles to load, as they will mess up the colors.

      Thanks once again for your expertise and recommendations!

        July 23, 2014 at 2:43 am

        You could try a “native” preset with DCCS 1.5.3 and choose ICC v2 profile, not an v4. After calibration is done and a profile is made with monitor behaviour you can test it with ArgyllCMS/DispcalGUI. No drivers needed for your i1DisplayPro, just “options->detect displays and devices” at first run.

        If you run a “tools->measurement report” it will check 2 things:
        -white point agains daylight (or black body) curve, I think that DCCS “Native” preset will perform badly here if native white of your unit is far from daylight.
        -profile accuracy, that means if ICM profile stores actual display behavior in this mode.

        Simulation capabilities of standard/synthetic profiles like sRGB/AdobeRGB can be performed with some options but for Photoshop and working in a 10bit enviroment white point & profle accuracy are enough. Testing sRGB simulation/indetity is useful for web designers because browsers like Internet Explorer are no color managed.

    There doesn’t seem to be a good solution to calibrate this monitor. Even if you use Dell’s software it only works with the i1DisplayPro and this is not a true spectrometer thus not able to properly interpret the Dell’s GB-LED backlight according to Anandtech: (See last paragraph)

        -Plug the device (or plug the device in Virtual machine if you did that trick, refer to your VM documentation to read about how to plug USB devices to VM)
        -Run i1Profiler.
        -¿Does i1Profiler recognize your device? ¿does it show “DEMO mode” in screen profiling?
        If answers are 1) YES and 2) NO it should run DCCS without problems.

          I have the i1Display Pro purchased from BH Photo. It was not purchased from Dell. Also I’m not going to run VM at this time. I think I’m good to go except for the controversial native VS Adobe RGB issue that Nasim is going to try out and report back to us on.

    And Anandtech article is FALSE. DCCS software has some inacuracies due to the way it mess up with brightness after white point, but it IS NOT related to i1DisplayPro colorimeter.
    DCCS 1.5 or higher also works with i1Pro/i1Pro2 but do not expect better results using them.

    RG_Phosphor spectral correction for GB-LED backlight is EXACTLY taken from an U2413, just check the EDR or CCSS trasnformation. Anyway this display can be properly calibrated in GPU with an AMD or nvidia Quadro with ArgyllCMS and an i1DisplayPro + RG_phosphor.ccss

    By the way cheap (1000euro or cheaper) spectrophotometers like i1Pro/Munki Photo cannot measuse properly blue from any monitor’s LED backlight. It’s due to their poor optical resolution, 10nm, and the narrow spikes of blue led emision. Just pick up a i1Pro, use the “high res/high noise” driver in ArgyllCMS to read GBLED spectrum in 3.3nm and you’ll se how it aproaches i1DisplayPro+RG_phosohor measurement under ArgyllCMS/DispcalGUI.
    i1Pro makes a “yellower” white point read ~2dE than i1DisplayPro and an accurate spectral correction, being the i1Displaypro more acurate when compared the two measurements with a lab grade spectrophotometers (<5nm optical resolution)
    Even i1Pro2 is not a "reference" device by any means, it is just an affordable spectrophotometer for primter profiling without UV cut.

    So what is the least expensive way to calibrate this monitor? My Samsung 27″ just died and I’m contemplating the Dell 3014. I do professional photography (part time) and need to calibrate the monitor for obvious reasons. On my old monitor I used SpyderExpress 2 and while older, it sufficed. I’m now looking at sinking a grand in another monitor and don’t have the finances to sink $2500 in a i1Pro kit. Thanks!

      -Any GB-LED monitor can be measured properly with a i1DisplayPro or Color Munki Display (the same device but 4-5 times slower and a not very good software package).
      -Any monitory can be calibrated properly in GPU by an AMD or nvidia Quadro graphics card because of their high bitdepth LUTs. This statement is NOT true for nvidia gamer cards or intel integrated graphics due to ther limited bitdepth LUTs at 8bit (banding, “stairs” in gradients.. very noticieable in widegamut dispalys working in 8bit/channel enviroments).
      -In order to calibrate internal LUT3D and use its advanced functions of gamut emulation of the new GB-LED models from Dell or BenQ (PG2401PT), you need their software and this software only works with i1DisplayPro/i1Pro/i1Pro2. This is because Xrite made that software (i1Profile customized).

      So the cheapest way to calibrate a Dell’s GBLED at its NATIVE GAMUT is a cheap pasive AMD graphics card able to output displays native resolution (1920×1200, 2560×1440, 2560×1600) and a Xrite’s color munki dispaly using ArgyllCMS/DispcalGUI and RG_phosphor spectral correction while the monitor is in “Custom color” OSD mode. This is just the cheapest way to obtain a proper calibration.

      The optimal way to do that is an i1DisplayPro (200 euro), an AMD FirePro or nvidia Quadro (entry level is Firepro v4900 or Quadro K600 at 170 euro). With these devices you can:
      -Use CAL1/CAL2 with Dell Color Calibration Solution 1.5.3 and see if its results pleased you. Make ICC v2 profiles in order to validate them with ArgyllCMS/DispcalGUI.
      DCCS 1.5.3 limitations are no L* gamma and some issues in neutrality of grey gradient due to a low number of native gamma measurements in calibation process. Xrite, Dell and Benq does not care much about that issue… do not expect lots of software updates.
      -Use “Custom color” OSD mode to calibrate in GPU at full native gamut and whatever white point and gamma you need . Without LUT3D help some RGB levels will be lost for L* gamma (<10%) but usual gammas like 2.2 or sRGB gamma could be obtained without much effort (<6% of 256 RGB levels lost). Use ArgyllCMS/DispcalGUI to perform this kind of calibration.
      -GPU calibration in factory gamut emulation modes (sRGB and AdobeRGB) are posible, but keep in mind that any white point adjusment will result in some RGB levels lost. This is because you have no access to monitors RGB gain controls so it is done in GPU. Stay near D65 in these modes, warm daylight whites requite a lot of blue levels to be lost. Use ArgyllCMS/DispcalGUI to perform this kind of calibration.
      -Use 10bit/channel monitor capabilities

        Thanks for sharing with us your knowledge on colors. I’ve learned a lot regarding this as I’m planning to upgrade my monitor and buy a Dell U2413. Together with this I’d buy a X-Rite i1Display Pro for calibration.

        My videocard is a AMD HD4850 (a bit old, but I don’t do much gaming, so it attends me perfectly for now and I could save some money to spent on a good calibration device). You say that AMD cards do have a high bitdepth LUTs. Is that the case for the HD4850 too or should I change my videocard as well?


        • ColorConsultant
          July 24, 2014 at 10:45 am

          AMD (former known as ATI) has been building highbitdepth LUTs in their cards since 2005, perhaps earlier. Very old models like ATI x850 of these years had 10bit LUT in order to offer 8bit DVI output without banding. It’s an old technology and of course any AMD HD4000 series like yours will be enough for GPU calibration. Nvidia is 10 years late in calibration quality on their non proffesional cards.

          With an AMD HD4850 you won’t be able to use the Photoshop’s 10bit workflow (feature only for proffesional cards like Quadro or FirePro) as described by Nasim Mansurov in his articles, but even if you do not use DCCS and you calibrate in GPU with DispcalGUI you won’t get banding or steps.
          You can even buy an Asus PA249Q or HP Z27i (GBLED AdobeRGB 99%, non hardware calibration but they have not overshoot issues which dells have)
          I mean you can buy whatever widegamut monitor you want without suffrening banding after calibration.

    Wow and thanks for the response. I just ordered the Dell 3014 and an iDisplayPro. I get them Friday. I’m not completely new to color calibration as I understand the basics, but I’ve been using a Samsung 275T (PVA panel) and a SpyderExpress2 for the last 7 years. Time to upgrade!

    I have a latest generation AMD video card, the Dell 3014, and iDisplay Pro. Couple of questions: Do I need to even use the DCCS software? Can I just use ArgyllCMS/DispcalGUI? I’m really good with computers and like to minimize software running on my computer for example; after creating an ICC file on SpyderExpress I uninstalled the software and set the created ICC file to load with windows. Is this the whole idea and can I do this with ArgyllCMS/DispcalGUI? To create an ICC profile to load with Windows7 64-bit?

    Things I’m not sure about:
    – Not sure what is meant by “validating” ICC profiles from DCCS with ArgyllCMS/DispcalGUI?
    – Your last two paragraphs I’m a bit lost on. Sorry. I fly airliners for a living so I can get this but need to start with more basics and work from there.

    I really really appreciate the help/input!

    I re-read the article and all comments; especially yours. I understand now that you need DCCS software to write to the monitor (CAL1 / CAL2) and that ArgyllCMS/DispcalGUI won’t do this.

    If I just want to create an ICC profile to run in Windows I can just use ArgyllCMS/DispcalGUI and not DCCS but this won’t take advantage of the LUT tables correct?

    Which method is preferable? I use my system mainly for Photoshop CS6 work and basic internet (email/browsing, etc). If I do use DCCS which color space do you recommend using in CAL1/CAL2? Native? sRGB? AdobeRGB? I work with RAW files in CS6 and output the final to jpegs to send to others and occasionally sent off (uploaded) for printing.

      “- Not sure what is meant by “validating” ICC profiles from DCCS with ArgyllCMS/DispcalGUI?”
      That means that you test how good the calibration and profiling was in the internal LUT3D of your display. Valitadion bundled with DCCS or i1Profiler is not very good, ArgyllCMS/DispcalGUI is more useful. ArgyllCMS needs ICC profiles to be “Version 2″, it is not able to validate version 4.
      As stated in a previous comment it checks two things:
      -which whitepoint you get and if it is closer to daylight curve.
      -it checks if actual monitor behaviour match what is described in the profile, that means that a color managed aplication will work properly in that configuration.

      “If I just want to create an ICC profile to run in Windows I can just use ArgyllCMS/DispcalGUI and not DCCS but this won’t take advantage of the LUT tables correct?”
      Yes you can but you won’t be able to use gamut emulation. With that I mean to set R,G,B coordinates of the three primaries at arbitrary locations inside the native gamut. For example “sRGB”, or an IPS tablet gamut in order to simulate its screen and design an application user interface in non color managed enviroments.
      As stated above you can calibrate in GPU: Custom color (full native gamut), sRGB mode (factory LUT3D calibration with gamut limited to sRGB), AdobeRGB mode (factory LUT3D calibration with gamut limited to AdobeRGB)
      The first one allows you to set an arbitrary whitepoint without loosing RGB levels and use full gamut of display. It will be the choice for general photo editing: sRGB images, AdobeRGB images, eciRGBV2 images…
      The other two allows you to work in a limited gamut enviroment but any whitepoint corrections will result in RGB levels lost in GPU. I mean if factory calibrated sRGB mode has a non daylight cool white, when argyllCMS corrects it, it will limit the blue channel to 0-240 range (just an example) not 0-255.
      If you do not want to use DCCS (I will use both: ArgyllCMS for “Custom color” and DCCS for AdobeRGB and sRGB emulation) you need to calibrate “Custom color” OSD mode for general Photo editing and “sRGB” factory calibrated mode to use with no color managed software like Internet Explorer.

      “If I do use DCCS which color space do you recommend using in CAL1/CAL2? Native? sRGB? AdobeRGB?”
      Unless you work with eciRGBv2 images or need some kind of special workflow like 5800K white, CAL1=AdobeRGB preset, CAL2=sRGB preset will work for most users.
      With CAL1 you can edit AdobeRGB tagged images without loosing red levels with an 8bit/channel card. That happens at native gamut because native red is outside AdobeRGB, I mean from black (0,0,0) to AdobeRGB Red you do not have 256 steps because at native gamut AdobeRGB is not (255,0,0) but something “like” (230,10,10). These are not actual values, just an example. That’s other reason to use 10bit/channel workflow, to minimize round errors due to color management. Look for Nasim Mansurov article on that subject, a Quadro K600 or an FirePro V4900 are affordable (160 euro) entry level 10bit graphic cards.
      With CAL2 you can work in non color managed enviroments as if you had a normal sRGB monitor.

      Maybe it’s to late to say this but models like NEC multisync PA272W (2560×1440 GBLED AdobeRGB 99% but has not full LUT3D hardware calibration, at least in Europe) as average will have a more uniform screen than U3014 and “similar” price.
      Since you have an AMD graphics card it would be calibated without banding with ArgyllCMS/DispcalGUI inside GPU LUTs. It is a GBLED AH-IPS monitor like U2713H, but will be likely more uniform and it has not overshoot issues of U2413/U2713H/U3014 models. U2413/U2713H are great displays for their price but ~1000 euro price for U3014 in some EU contries is too high IMHO, I’ll check avaliabilty and price for that Multisync PA272W.

    I’m going to read your statement a few times and hopefully it will sink in! ;-)
    I chose the 3014 based partially on reviews and the fact that I wanted to go larger than the 27″ I currently use. I also wanted to stay 16:10 as I would rather have the vertical space. Don’t like the 16:9 monitor format. The NEC looks like a great monitor but I got a good deal on the 3014 and the NEC would be $500 more USD for me. I would love to have one of the upcoming Samsung/Asus IPS 4K, 32″ monitors but they will be in the $3K-$4K range! Maybe in a couple years? The 3014 just seemed to be the best for larger than 27″, 16:10, and I got it for $800USD. I’ll see tomorrow if I like it??

    So if it were you with the iDisplayPro, what steps would you take to calibrate this display for normal computer use (internet, email, etc) and editing RAW images in Photoshop? Something like:
    – Run DCCS and select “sRGB” +RG_phosphor.ccss and save that to CAL1
    – Run DCCS and select “AdobeRGB + RG_phosphor.ccss and save that to CAL2
    – Install and run ArgyllCMS/DispcalGUI to have it validate the ICC files? (Is this intuitive in DispcalGUI?)
    – Next?

    $500 USD is a bargain!

    “- Run DCCS and select “sRGB” +RG_phosphor.ccss and save that to CAL1″
    No need to “+RG_phosphor.ccss”, please read Nasim’s article. It’s done automatically

    Regarding ArgylCMS/DispcalGUI at 3rd step just download and unzip, no need to install.

    Once done, run dispcalGUI and select “bin” folder of ArgyllCMS (1st run only)
    Then select Options->detect screen and instruments(1st run only)
    Then select Tools->import colorimeter corrections and select “C:\Program Files (x86)\X-Rite\Devices\i1d3\Calibrations\RG_Phosphor_Family_25Jul12.edr”, that will make CCSS file (1st run only)
    Then select in “correction” combo box “RG_Phosphor_Family_25Jul12.ccss” (1st run only)
    Your enviroment setup is complete for a GB-LED display.
    Just make sure every time you run it that the first combo box is always “Settings: “. That means that profile loaded into GPU will be allways the profile set in Control Panel->color management as “default”.

    To verify any ICC v2 profile just select Tools->measurement report, choose a “ti1″ set, “extended” for example, all to default values, make sure your currect profile is selected in the botom box and click “measure”. After measuremets an HTML report will be generated, you need to enable Javascript.

    Also you can test screen uniformity in detail (i1Profiler or DCCS uniformity test is not very good). To do that Tools->Measure display device uniformity. 3×5 patches on screen, measure each one.
    Onec done an HTML repoprt will be generated. Color uniformity will be detailed in DeltaC (the one which matters, not correlated color temperature as in i1Profiler)

    ArgyllCMS/DispaclGUI is a powerful and complex package, you can even profile mobile/tablet devices in order to simulate its RGB(0-255) screen behaviour. For further info, ask in its forum:

    Nasim, this is why calibrating on the U2413 is confusing and costly (having gone from Spyder4Pro to i1 Display Pro!). Can you make sense out of all of this for us?

    • 27.1) ColorConsultant
      July 25, 2014 at 1:48 pm

      It has been told before, read the thread:
      -First of all because a Spyder4 is a low quality device compared to Munki Display and i1DisplayPro. Slow and inaccurate
      -Second, Spyder4 at factory setup DOES NOT SUPPORT GB-LED BACKLIGHT. It won’t measure properly an Asus PA249Q, nor NEC Spectarview PA242W nor new Eizo ColorEdge.
      -Third, the LUT3D calibration software has been made by Xrite… so non Xrite devices don’t work and won’t work

      So the LUT3D calibration limitations seem pretty reasonable. You bought the wrong colorimeter.

    Hello everyone,
    I am following the discussion because I too am trying to calibrate a dell u2713h.

    But I have two problems
    1 finished the calibration process with DCCS, the LUT calibration curve remains a straight line

    2 if I try to validate the ICC profile crashes immediately with “dispcal.exe stopped working”

    I am using windows 7 64, with the probe i1 Display Pro, video card geforce gtx 660

    Do you have any suggestions?

    Thanks to all

    July 27, 2014 at 11:53 am

    I got the monitor and am very pleased! The default when I turned it on was much too saturated. I didn’t change the defaults and ran DCCS with the iDisplayPro. I put sRGB in CAL1 and AdobeRGB in CAL2. On the monitor’s OSD if I got to profiles I have 4 choices: sRGB / AdobeRGB / CAL1 / CAL2. sRGB and my CAL1 seem identical except the CAL1 sets the brightness to 22% which is way too dark. sRGB sets it to 50% which is perfect. What I’m not sure of…….

    – is the sRGB just a standard, uncorrected value from the monitor? Or is has it been modified during my calibration?
    – If I use CAL1 can I just up the brightness without throwing the calibration off?

    In my Windows Color profiles I there are three ICC files: sRGB (from my calibration), AdobeRGB (from my calibration), and Dell 6500K (which I’m assuming was installed with the monitor drivers)?

    • 29.1) ColorConsultant
      July 27, 2014 at 1:59 pm

      1) sRGB/AdobeRGB are factory calibration at 50% /50% brightness contrast. This is TOO much (>200cd/m2) IMHO, eyes hurt in dim rooms but it depends on your ambient light.
      Your CAL1 is right, 120cd/m2… it’s just what you configured. If you do not like it, re-run DCCS CAL1=sRGB and whatever cd/m2 you want (80-300)

      2)No, may shift white point. Same applies to factory calibration (which as emulation mode -RGB primaries coords- are good but as calibration are bad)… they are calibrated at this contrast and brightness, you move it, you loose it (nothing important is lost). Gamut should remain “constant” (sRGB/AdobeRGB) in these modes under sensible range of contrast/brightness (40-70 / 10-70)

      3- Make sure that 2 first profiles (sRGB/AdobeRGB) are yours, not the “standard” profiles. Bad and confusing names, better try a full decriptive name like “U2713H_CAL1_sRGB.icm” for the next calibration. You SHOULD change default profile in Windows Color Management upon OSD mode swich (also restart Photoshop and most color managed apps). Better put a direct link to that on your desktop.
      “Dell 6500K” is a synthetic profile with native gamut (that is full gamut you saw oversaturated but it is right, you just do not have an eciRGB image to see it properly) an “nominal” native gamma. It contains no GPU calibration, so selecting it (as CAL1/cal2 profiles) should clear the GPU LUT.

  30. 30) Todd
    July 27, 2014 at 3:33 pm

    1) This makes sense to re-run the calibration using a higher cd/m2. I really really like the 50% brightness though. It’s perfect for me and not too bright. I guess I just need to try different cd/m2 until I get close.

    2) Understand

    3) I’m still a little confused on changing the monitor’s OSD settings changing the default .icm file in Windows Color Management. Let’s see if I have this correct…….So let’s say I re-run the calibration using sRGB at 200cd/m2 under CAL1 and name the icm file “ToddsRGB.icm”. Let’s say I’m happy with that. Then I should go into Windows Color Management and select “ToddsRGB.icm” as the default profile AND select CAL1 on the monitor’s OSD? I should make sure I’m running the default icm file in Windows the same as the selected OSD mode?

    NOTE: I really like the 50% brighness and what I’m seeing on the screen now which is Monitor OSD – sRGB and the Dell D6500.icm file as the default. But what I don’t understand was why is was that oversaturated full gamut when I first turned the monitor on but after calibration and still being on sRGB on the OSD and running Dell D6500.icm as the default icm; why does it now look good and not oversaturated?

    • 30.1) ColorConsultant
      July 28, 2014 at 1:08 am

      3) Yes, at least before running color managed apps. Non color managed apps does not care about that.
      Photoshop (or GIMP) needs to know the exact gamut and gamma of your display so it can color manage any image profile to your “unique” display behavior (grey neutrality, gamma and gamut emulation inacuracies)

      A profile does only two things:
      -make grey neutral to an specific white point
      -informand JUST informcolor managed apps of actual gamut and gamma achieved.
      It does not limit gamut.

      So if you set Dell6500K.icm as default, windows desktop does not care since it is no color managed, but if you set Standard or Customcolor (or uncalibrated CAL1 or CAL2) in OSD, these modes have full gamut so your desktop colors and wallpaper (sRGB images at 95% certain) will be “moved” (RGB values unchanged) to native gamut so it appears to be oversaturated.
      Windows destop is oversatured too on CAL2=AdobeRGB but since AdobeRGB red is almost identical to sRGB red you only see “partial” oversaturation in cyan/green.

      Let’s explain it with examples:

      *Custom color + GPU LUT calibration in default profile + wallpaper = oversaturated, but neutral grey
      *Custom color + GPU LUT calibration in default profile + Photoshop sRGB tagged image= correct colors
      *Custom color + dell6500K.icm as default profile + wallpaper = oversaturated
      *Custom color + dell6500K.icm as default profile + Photoshop sRGB tagged image= correct gamut in image (not oversatureted) but uncalibrated display response (may have not neutral grey)

      *CAL1=sRGB + Todd_sRGB.icm as default + wallpaper = correct colors
      *CAL1=sRGB + Todd_sRGB.icm as default + Photoshop sRGB tagged image= correct colors (wont be able to display AdoberGB image, out of gamut)
      *CAL1=sRGB + dell6500K.icm as default profile + wallpaper = correct colors
      *CAL1=sRGB + dell6500K.icm as default + Photoshop sRGB tagged image= extremely UNsaturated colors

      *CAL2=AdobeRGB + Todd_AdobeRGB.icm as default + wallpaper = saturated colors, neutral grey (stored in LUT3D)
      *CAL2=AdobeRGB + Todd_AdobeRGB.icm as default + Photoshop sRGB tagged image= correct colors (will be able to display AdoberGB images properly)
      *CAL2=AdobeRGB + dell6500K.icm as default profile + wallpaper = saturated colors, neutral grey(stored in LUT3D)
      *CAL2=AdobeRGB + dell6500K.icm as default + Photoshop sRGB tagged image= UNsaturated colors

      ALL color managed apps need to know the actual gamut of whatever OSD mode that your display has currently active. It is done with the icm profile set as default and for most apps it is done when you run the app, so default profile changes needs app restart.

    I’ll read through this when I get home from work tonight.
    Last night a recalibrated using DCCS. I chose sRGB/CAL1 with a luminance of 210cd/m2 and it ended up giving me 52% brightness and 47% contrast. I’m happy with that. Seems slight blue tint to me but that may just be my eyes and it’s just slight.

    So I’m now running CAL1 (sRGB/210cd/m2) and the icm file that this created as the default.

    So now I need to run ArgylCMS/DispcalGUI and test the output?

    @ColorConsultant & Nasim:

    I have a U2713h display calibrated via Xrite iDisplay Pro for AdobeRGB @ cd/m2 in CAL1 and sRGB in CAL2 (with a way too high brightness set when I last calibrated it…), using CAL1 most of the time.

    Some questions:

    1) Do you vote for Native over AdobeRGB as one of the calibrated slots? Is it a trap to work with “flatter” profiles for fear of making excessive edits to compensate?

    2) What brightness would you recommend for sRGB?

    3) Having worked with CAL1 most of the time and its low brightness and bland AdobeRGB colors (to my eyes) I’m afraid that I have overcompensated with my edits in LR in terms of vibrance and saturation leading to quite over-the-top results when viewed on un-calibrated screens and mobile devices (especially Samsung OLED screens make some pics look hideous). Would you recommend always reviewing an album also in sRGB mode prior to uploading to at least have a feel on how it will appear on the majority of devices out there?

    4) LR doesn’t let you edit in sRGB, only Adobe Standard and Camera Profile (approximations). Yet it allows for export to sRGB. Isn’t this a bit confusing?

    5) In Windows 7, it appears different color profiles are used when viewing thumbnails in Explorer as opposed to opening them in the Windows image viewer (which shows the faithful to LR version of a pic). Opening in e.g. FastStone Image Viewer looks way over-saturated (I’m guessing it defaults to another color profile). How can one force consistent rendering across all software on a Windows machine and avoid this madness?

    Thanks in advance

      And now after hitting re-calibrate I seem to have had CAL1 and CAL2 mixed up.
      Meaning that CAL1 was for sRGB @120cd/m2 and CAL2 for AdobeRGB@250cd/m2.

      250cd/m2 is killing my eyes for sure… I’m guessing I’ll have to set both to e.g. 180cd/m2 so that they are comparable (don’t know why the tool does not default to equal brightness values for different color spaces…).

      The conclusion thus it that sRGB was very lifeless to my eyes and I exaggerated the vibrance and saturation in LR to compensate, but how does that explain the bad rendering on e.g. my un-calibrated office monitor and mobiles? Do those screens deviate from sRGB that much?

      AdobeRGB on the other hand looks too vivid and I’d have to tone my edits down to get something tasteful.

        Mark, I’m afraid that Nasim is no longer monitoring this thread. He promised that he would relook at his calibration methodology, but has not returned to this column. He convinced use to buy the U2413 and i1, and then left us flapping in the wind. Meanwhile I am happy with my calibration which is native on Cal1 and Adobe RGB on Cal2. And native does give a higher color palette than Adobe RGB- confirmed by the 3d pattern that compares the two in the software program.

          Jay, no, I am still here and this still is in my to-do list. To be honest though, just like you, I am very happy with Native in CAL1 – that’s what I use the most. I compared the color gamut from Native profile to AdobeRGB and the color output was superior, just like you’ve noticed. I don’t have green white either, it looks really good to my eyes.

          I am still planning to re-calibrate my setup when I have a chance in custom mode to see if I can spot any differences and compare the calibration. Will report as soon as I do that – just have too much on my plate at the moment :(

            Hello, glad you are still monitoring this thread. :-)

            Would it be possible to get some answers to my questions above? Actually let me rephrase them here (also adding a few extra ones):

            1) Is RGB supposed to look more lifeless (less vivid) than AdobeRGB?

            2) What can one do in one’s workflow to avoid creating images that look good on their calibrated screen, but terrible on the majority of un-calibrated screens out there? It’s hard to justify to people that “hey, it looked good on my Dell”… This is my #1 concern at the moment.

            3) Why does every program on Windows seem to pick its own color profile giving different output?

            4) Should selected brightness be the same in all calibration modes?

            5) Shouldn’t LR be able to render color using the monitor profile? I mean, imagine having your screen set in sRGB, yet LR only supports Adobe Standard and Camera Profiles. Then, for web usage, we go export to sRGB again. Doesn’t working with a different color profile in LR than what your monitor uses guarantee inconsistencies?

            Thanks and sorry for the barrage of questions…

              August 6, 2014 at 1:14 am

              1) I guess you wrote “sRGB” not “RGB”. The answer is yes. sRGB has a less saturated green, cyan and orange-yelow. It has a different gamma too, with “brighter” near black greys.

              2) Nothing for ALL displays. Samsung OLEDs (Galaxy S* phones) that you stated in previous post are widegamut escreends with a gamut wider than U2413 or NEC Spectraviews.
              Tthe thing you can do is to transform an image to an SPECIFIC display taht you can measure by yorself.
              This is done with ArgyllCMS/DispcalGUI and remote measurements. DispcalGUI opens a web server, phone or tablet conects to that local network web page and start measuremets in order to PROFILE (not CALIBRATE) device. Once you have a profile with actual behaviour of that portable device:
              -convert you image (not assign) to that profile. Device should render it properly if you did it the right way.
              -or use Colibri or other color managed viewers for android with the profile you created.

              3) Windows desktop is NOT color managed (and its a bit advantage over OSX but only if you know what are you doing and have a LUT3D calibratable device).
              A windows application has declare itselft explicity “color managed”.
              -PS/LR/GIMP are color managed
              -Desktop is not color managed (full gamut and hardware gamma)
              -Windows photo viewer is color managed but do no understand some types of LUT profiles.
              -unless an app is color managed, it behaves as desktop (which is useful to IT mobile developers if they have a LUT3D calibratable monitor).

              4) whatever your workflow needs. You may have custom mode to 90-100cd/m2 for softproof and CAL1/CAL2 to 120cd/m2 for editng purposes.

              5) It actually renders images acording to your monitor profile. Monitor profile IS A FILE which OS publish as default behaviour of your screen. Switching monitor’s OSD modes does not alter that info on your OS, you must do it by yourseft (and restart LR in order to app to notice it). Regarding lack of options in LR… use PS. It is their fault your monitor’s.

              Thanks for your explanations.

              I guess that explains why the desktop / thumbnails / shortcut icons look way too saturated compared to e.g. color managed applications.

              I currently calibrated CAL1 for Native, CAL2 for sRGB, as Nasim did. Native looks way over-saturated…

              Suppose I’ll check my processed photos in both modes before I publish them, to make sure the results lie somewhere in between.

              With regard to LR, I was really confused about how it can render AdobeRGB with a monitor set to sRGB (or any other color-space mismatch)…

              A lot still to learn I guess.

              @Mark Pitsilos (comment 72)
              It cannot render AdobeRGB in an sRGB monitor. But it uses monitor profile and its rendering intent (better use relative colorimetric) in order to know how to clip gamut.

    Did anyone noticed Backlight Bleeding issue on his Dell U2413 ? like shown here
    My new monitor has the same issue. Is it an issue at all or it should be uniformly black?

    • 33.1) ColorConsultant
      August 10, 2014 at 3:36 pm

      Dell, Asus, LG, Benq do not gives you waranty of uniformity (color or brightness) in their screens. They could be good (most probable) or as bas as that example (but pretty uncommon in GB-LED units). Return for refund.

      If you want that kind of waranty you should look for NEC Spectraviews or Eizo Coloredge ( between 1400-1600€ for 24″ screens with the same panel, backlight and gamut that U2413).

      If that is too much money buy Dell/Asus/benq online and if not pleased return for refund and try the same model in other store. That kind of backlight bleed is NOT coomon in photography GB-LED models.

          August 11, 2014 at 1:30 am

          Benq PG2401PT is like U2413 (same customized version of i1Profiler for HW calibration) but without overshoot and hard to lower brightness below 100cd/m2, so for Photo (some softproof conditions) it is better U2413.

            Probably i don’t understand,
            If Benq has no overshoot and no hard to low brightness(ununiformity as i understand), then why Dell is still better for photo ?
            BTW, Benq is twice in price(~950$) when compared to Dell.

              August 11, 2014 at 5:35 am

              I’m not talking about uniformity. I’m talking about maximun brightness.

              Some softproof enviroments use 80 or 90 cd/m2 and acording minimum for Benq is 100, so Dell is better (unless you lower RGB gain in GPU calibration, aln lower contrast and sacrifice those things to lower overall brightness… and in that case Dell will be better too).
              Since overshoot issues do not matter for Photo editing is Dell 1 vs Benq 0.
              Not really an issue, 100cd works for most people.

              I have not seen Benq in stores in my country (Spain) but I would NOT pay more than 500 euro +-50 euro for the Benq. This Benq model is NOT worthly of 900 euro by any means (it’ just an afordable model like Dell), in that prices save a litle money and get a 24″ NEC Spectraview PA242W with HW calibratable L* gamma for eciRGBv2, a tue uniformity compensation and those things… IMHO $950 US for that Benq model is a theft.

So much so, that I’m not going to waste my time returning mine since I don’t notice it anyway when in actual use. I will however, not buy another one. I’ll wait and see what new ones come out the next year or so.

              As stated above, Dell (or other non premium labels) does not guarantee screen uniformity, none of Asus,Dell, LG models have that. Some of these trademarks allow you to ask for replacements, but uniformity is not guarantee.

              If you need that kind of certain without playing “replacement lottery game” buy premium models like Spectraview or Coloredge.

      I do have some monitor screen bleed on the right side- but not very much. How about someone else? Here is a simple way to test: turn off your lights and play this youtube video:

      Check the sides to see if you see any light bleeding over. I think all IPS monitors have some bleed.

      • 33.2.1) ColorConsultant
        August 12, 2014 at 7:31 am

        No, it’s a common “myth”, a very FALSE one.
        Bleedeing comes from:
        -backlight un-uniformity -> since IPS have lower constrast than some VA panels, their blacks are “brighter” and un-uniformities are more easily spotted.
        -bad assembly, a.k.a. “china quality”, panel + backlight has too much pressure in some corners due to bad assembly.

        Your defective unit is NOT a common issue in GBLED Dells. Return for refund, or pay for a Spectraview Reference PA242W, which are GBLED AH-IPS from LG an of course they HAVE NOT any kind of bleeding.

          I would love to have the NEC, but at $1299.00 US, I am happy with my $429 U2413! I might consider it for my second monitor some day, but by then, the 4Ks will be marked down! The problem with returning units is, you are not sure if you will get a better one. Yes, quality consistency is an issue. But how does NEC handle the quality? Do they reject the ones that are bleeding- do they even check for it? I’m sure they are maybe even done in the same factory as the Dells!?

          Nasim- please check your U2413s for bleeding. And give us your working opinion about minor bleeding of monitors.

          • ColorConsultant
            August 12, 2014 at 1:23 pm

            NEC Spectraview and Eizo coloredge had minimum quality for all its panels: uniformity in color and in brightness. If not met, returned to LG or Samsung (panel manufactures).
            Besides that they have a customizable uniformity compensation at the expense of contrast and even Eizos had a feature to ensure fast color warmup.
            And those monitors do their job. DICOM gamma is defined in absolute luminace ranges not in relative to your brightness like 2.2 or L*. They need to ensure that kind of uniformity, and that’s paid.

            If no money for that high end models, you play lottery.
            -Lotto with not so good odds at afordable WLED sRGB monitors (LG,asus, del..)
            -Lotto with very very good odds at “afordable” GBLED photo monitors .

            Take it as you want but this is an issue limited to your unit and a few more. Saying all IPS sufrer from sonme kind of bleeding is just FALSE.
            I’ve seen lots of these cheap GBLED photo monitors and they no suffer bleeding, but some suffer some color uniformity problems (most of them “aceptable”, some of them not). That’s were uniformity measuremet form DispcalGUI enters the game, measure, check if it’s “aceptable” for you and if not, return for refung and try another one or save cents for high end.

              August 12, 2014 at 3:48 pm

              I do see that the Dell/x-rite software has a uniformity test. Mine checked out well except in one area. I pushed a slider and it compensated for it. Can you explain what this does?

            • ColorConsultant
              August 13, 2014 at 12:51 am

              Slider does not compensate anything, it does nothing to your monitor. Slider sets tolerance, how bad it needs to be a measute in this test to render as “green OK” or “red BAD”. It’s like cheating in solitarie.

              By the way i1Profiler uniformity test is wrong. Correlated color temperature means nothing about color acuracy or uniformity (because for example there are green-white and magenta- white with exactly 6500ºK CCT, correlated color temperature is a curve – many points, many colors- not a single point in a colrospace. That is the reason we say “D65″ the intersection between 6500K curve and Daylight whites curve). If you want to run a proper uniformity test run the one bundled with DispcalGUI with test uniformity at 4 luminance level and gives you deltaC (chomaticity) difrereneces from the center for each one and an average value.

      All the lights off,pitch black room,no bright surfaces near the screen(to prevent white reflection), camera – set camera on same Kelvin as you will set on monitor(i set 6500 for camera and screen), shoot with dslr for example with f4,don’t burn the white on/off button to prevent amplification of the real brightness.

      Measure it!

      -Options->detect colorimeter and screen if not recognized after first run (optinal)
      -Tools->import colorimeter corrections, auto. Choose RG_phosphor.
      -Tools->calibrated display report. There in a text screen it will report:
      *brightness white cd/m2
      *brightness black cd/m2
      *gamma at 50% grey (if you want to see full gamma which in sRGB is NOT constant, run a full report “measuremet report”)
      *4 values of white in CCT, CDT, VCT, CDT and distance to daylight/blackbody curve (delta E2000). The ones that suits better photo work is CDT (correlated daylight temp) or VDT (visual correlated daylight temp) -> if you did not choose RG_phophor as spectral correction, these numbers will be wrong.

      You can measure brightness with i1Profiler, but DispcalGUI is far more complete in its reports and show things that i1Profiler or even Spectraprofiler software for $1400 NEC does not.
      I do not know why is so difficult to accept that in GPU calibration (not LUT3D) and in profile validation and verification GNU software is light years ahead of these companies like Basiccolor, Xrite or Datacolor. Basiccolor and Xrite make fine hardware, very reliable and accurate but their software is behind their hardware.
      So you can use i1Porfiler and run its report and verifications, BUT THEY ARE WORSE than those obtained with ArgyllCMS/DispcalGUI. So you need this 3rd part software package if you want THE BEST.

      Regarding “low brightness” issue… maybe you haye NONE. It’s just that 120cd/m2 or the number you set is hust too low your your tastes, it is not a monitor problema and it is not a software related problem.

      Lets assume that you do not have access to a good colorimeter. The proper way to do this os tu actually calibrate your U2713HM with a WLED spectral correction.
      Standard or custom color osd mode should be used with driver’s ICM, since these OSD modes have native gamut. sRGB osd mode (factory) “could” be used with standard “SRGB profile” but this needs factory calibration to be accurate in gamma , gamut and white in order to work,

        Apple has fallen behind Windows in graphics certainly. Photoshop since CS4 has been 10 bit capable, and newer Windows machines are also 10 bit, while Macs are stuck in 8 bit even though wide gamut monitors with 10 bit and 14 bit LUTs are readily available at a decent price, notably the Dell U24513, which I have. I am using the factory aRGB even though I have an XRite i1Display Pro and Win 7 on Fusion 7 to run a hardware cal, because I believe it’s pointless to do 30 bit color through a 24 bit intermediate step.

      All these posts demonstrate one thing.
      Don’t buy monitors from companies that do not provide proper support and don’t understand calibration.
      Use a proper calibration device that is up to the task of hardware calibration not a half baked Spyder that can only fiddle with the graphics card.
      Stick with Eizo and NEC and XRite.

        Betty- well I guess that Nasim is no longer going to get back to addressing all of these issues. His article has created a firestorm of comments that continues to this day. Meanwhile, I continue to enjoy my Dell U2413 and I haven’t calibrated in months. Need to do that soon! But it seems very stable.

          After trying numerous times to calibrate both my U2713H and not making sense of what’s going on, even using my Spyder4Pro puck with DispCalGUI I gave up and deleted everything. I ended up resetting both monitors to factory settings and configured them to use sRGB Preset, I have continued to produce commercial work for clients with absolutely no colour issues. I’ve found despite countless calibration attempts made results remain frustrating. sRGB Preset with Brightness dialed down to 19 work well. White is white and prints match the screen (printing is not my core business). One of the screens has a very slight off white tinge but it’s not enough to matter in the images I edit.

          Spyder support wants me to enable calibration data sharing and gave me some instructions to follow. I did that once and didn’t get the results they had hoped I would. I refused to do anymore tests for them. They should buy their own hardware and release new software that works with GB-LED monitors. Meanwhile, on with my work until something workable comes along.

    I am a professional photographer working with two U2713H, Windows 7 64-bit, nVidia GeForce GTX 660. My calibrator is a Spyder 4 Pro.

    When I first calibrated the monitors, I noticed one of them had a very faint green tinge. No matter how many times I re-ran calibration, the result was always the same. Both monitors didn’t have the same white. Then I tried something different: I had White Point set to 6500K, Brightness to Native, and calibrated using RGB sliders. On the monitor, I chose Custom Color | Offset and slowly adjusted RGB values to closely match 6500K.

    What I ended up getting: R31, G31, B100 on one monitor and R28, G28, B100 on the other and only then I get both monitors to display identical white. Using this method with nVidia’s Digital Vibrance at 50% on-screen colours seem a tad over saturated. Adjusted sliders to 45% and it’s OK.

    I then printed some test images using the new profile and output closely matched the screen. I don’t know if I’m doing it wrong or not but I got both monitors to show same whiteness when before there was a very slight difference when calibrated the normal way.

      You cannot measure properly a GB-LED with an Spyder4. It’s a fact. Your only hopes rely on DispcalGUI, dispcalGUI driver for Spyder4 (read its manual) and Xrite’s GB-LED spectral corrections.
      Doing this you’ll be able so measure a GB-LED monitor… more or less. Poor hardware from datacolor.

      But you cannot calibrate its internal LUT. Since you have to calibrate in GPU and you have an nvidia, all calibratiosn will look awful in grey ramp: banding coloration.. and this is not because of dell but because of your nvidia. Get an AMD graphic card or a Quadro.

        Since posting my comment, I have ditched Spyder software and replacing that with latest version of DispcalGUI. It’s all set up with the GB-LED spectral correction and trying to make the most of the Spyder4 Pro hardware. The new setup isn’t the easiest to understand and I would appreciate help with the various settings on the DispcalGUI user interface. Also, it doesn’t seem to support dual monitor calibration, how do I go about setting two profiles. Should I go with Calibrate & Profile or Profile only?

    Jan, If you read the article and comments above, you will see that the Spyder products will not do. I’ve got the Spyder and the X-Rite both. The X-rite does the calibration within the monitor LUTs. The Spyder adjusts the output from the video card. So point made here is that you and I wasted our money on the Spyder because Dell went in with X-Rite on the design of this monitor. Best thing you can do now is loan out the Spyder to your non-Dell friends and get yourself a X-Rite!

    HDMI is a range limited Rec 709 signal, so it’s not even sRGB.

    I have been in an ongoing discussion in the Dell Community/photography life board about calibrating a Dell U2413 using the DellUltraSharpCalibrationSolutionSetup.exe in a virtual Win 7 running in VMWare Fusion 7 on a Mac mini under OS Mavericks.
    The self appointed expert there says you can’t do it because the device isn’t recognized and a couple other things, He says this is described in one of the other threads in the forum but can’t point me to it . So I’ll ask here. Can you or can’t you and if not why not.

      You cannot calibrate “cheap” (no 4k) GBLED Dells in OSX. You need a non virtualized Windows instalation. The main cause is that serial no must be read both on USB (which can be acomplished on a virtual machine) and with DCC/CI whicj needs access to physical output. Under a virtualized OS you do not have “physical” access to GPU hardware but to an abstraction with for example in VMware would be called something “VMWare SVGA” or something like that.
      So no, you can’t do it without a Windows 7/8 partition.

      Apple OSs have a lot of drawbacks to work in a pro enviroment, no 10bit workflow is one of them. Better switch back soon to a real OS for photo/image treatment like windows or you’ll be stuck with hardware that you cannot use at its full capacities.

    I too have just purchased a U2713H and have yet to find out if I can run it on my Macbook Pro 17. A call to Dell Tech center basically told me that the software program for the drivers is multi-platform {PS & Mac OS}….but when going to the page to download the drivers,….it asks which OS you are using and gives on PC choices. Anyone out there have any answers for this??

    • 48.1) ColorConsultant
      November 9, 2014 at 11:25 am

      To calibrate them in GPU you have DispcalGUI. It has OSX versions. If your macbook does not come with an AMD GPU like “a little old” macbooks you won’t be hable to calibrate properly ANY widegamut monitor unless it has hardware calibration for OSX. It is a hardware limitation of intel integrated GPUs and non Quadro nvidias.

      If you wish to use hardware calibration capabilities from your U2713H you will need to instal Windows in a partition of your macbook. As said in a previous message virtualization does not work. You can calibrate it on another PC with Windows and copy ICM profiles to your macbook. Another option is that after calibrate it on a Windows PC, you create a profile without calibration using DispcalGUI with your macbook, your Dell and an i1DisplayPro. I think that I posted in one of these comments how to do it.

        Thank you for your comment and help, Its good to know there is someone out there with the know-how and is willing to share.

        So here’s my update. I post this in a effort to be helpful to others as well.

        After a day chasing around Dell’s Tech Support people I ended up with one of their “experts” telling me that the two devices are NOT compatible,….and later after talking with the Tech people at Mac,….I called Dell’s people back and this one told me it was indeed compatible. At this point I’d spent all the hours of the day and would have to resume again the following day. The following morning I called Mac again and they had reviewed the specs on the monitor and suggested I make a call to X-rite.

        X-rite’s tech support person Bruce Wright knew exactly what the issue was and sent me a link to download the drivers and everything I needed to be able to calibrate the monitor. He had no answers why Dell doesn’t make these available on their site. Being I have owned a i1Pro display calibration tool, I was able to calibrate the monitor to perfection.

        So….for those who are interested in this particular monitor, but skipped over giving it consideration because its not OSX supported, …thats simply not true. X-rite is only too happy to share everything you need to make the monitor work for you.

        And Colorconsultant…..THANK YOU!!!

          I think that you have NOT actually calibrated U2713H internal LUT3D, the process that I think that you have performed is to download i1Profiler for OSX and perform a GPU calibration (the one that must be done in monitors without hardware calibration).
          If you did this, then ArgyllCMS/DispcalGUI which are avaliable to OSX would perform FAR BETTER than i1Profiler.

          Since this is (i1Profiler’s profile) a GPU calibration unless you have the kind of GPU I stated before, you will end with banding. This is not caused because you may have a Mac but because you have an nvidia GPU (if it is your situation),

            November 9, 2014 at 2:46 pm

            Colorconsultant…… I already have X-rites i1pro display program and tool. After downloading and installing the drivers that Bruce sent,…and followed his instructions I found myself looking at a X-rite profile that INDEED looks very similar to the one I have on my computer. However,…this one also has Dell’s name on it. Finishing this,….there was a very noticeable difference in colors. He had told me that without those drivers there was no way for me to access the Dell Color Solution program built into the monitor,….or have any influence on the LUT3D.

            Since Bruce was part of the team that put the X-rite program together for Dell,….and I’ll be talking with him again tomorrow to review everything, I’ll ask him about about the ArgyllCMS/DispcalGUI. {it should be interesting to get his response….}

              Just to be sure. Create a new calibration with that “tuned” Xrite software, this MUST be ICC version 2.
              After calibration a& profiling is done, inspect profile with DispcalGUI. If calibration curves combo IS NOT a PERFECT straight line, it is done in GPU, not in internal LUT3D, and Xrite’s people tell you a lie.

              If it is a straight line (and we “are willing to believe” that this is no just a profiling without calibration, that can be tested in another way), it would be helpful to post those drivers in a public server like mega, mediafire, or the oen you like most, since most Apple & Dell GBLED users do not seem to accomplish what you claim (LUT3D calibration under OSX for cheap no 4k GBLED: U2413, U2713H, U3014) ever after contacting Dell or Xrite’s people.

    You must click on Drivers For OS Deployment to reveal the download.
    Now i will be able to adjust the monitor’s LUT, although on a Mac I will be setting 256 points of a 16,382 point curve and that means massive amounts of interpolation.

      Please try to create a ICC v2 profile (must be version 2) with DCCS 1.5.3 for OSX and then inspect calibration curves and profile, just to ensure that this program is using LUT3D calibration and not GPU LUT calibration.

      That kind of massive amount of interpolation will be done in the same way in a hardware calibratable NEC or an Eizo, AND IT WORKS.

        November 22, 2014 at 9:01 pm

        I downloaded the DUSCS 1.5.3 and read the read me file. That was enough to make very hesitant to use the software to adjust the LUT on my U2413. The file says:
        Some built in Mac video cards are incompatible with the new generation Dell Displays. This can cause the
        Mac OS to crash and go into a reboot loop where the system will not boot to desktop. If this occurs, the
        User will need to disconnect the Dell display and boot the system with another display as Primary. Once
        Mac OS is booted, the User can connect the Dell Display and perform Calibration.

        Which video cards? Or what Mac models or build years? What kind of stupid warning is that? Why do they assume a parson even HAS another monitor?
        My only experience with Dell tech support was something I will never repeat. In order to talk to them you presupposed to provide some sort of product number that does not appear on either one of my Dell monitors. I got around that somehow, don’t remember what I did, but eventually I talked to some woman who apparently didn’t know that Dell makes monitors. Needless to say I didn’t get any support from support.

            The warning says nothing about Thunderbolt or minidisplayport. I’m afraid your opinions are as misleading as your spelling. 10 bit is not a panacea, Windows driving the same monitor with 10 bit would just encounter the 8 bit +FRC problem. Setting a 14 bit LUT with even a real 10 bit isn’t that much help. Insulting me and the telling me you can help me is not something I’m interested in. Getting Dell to publish software that works is.

      No hardware calibration for OSX with U2413, U2713H or U3014. You need windows.
      Under OSX you can perform a GPU calibration with i1Profiler, your older software or DispcalGUI.

      I do not know what device you name by “Eye1″ but if it is a “eye 1 display 2″ you cannot measure properly a GB-LED monitor be it Dell or Eizo or NEC. You can’t. You need an i1DisplayPro (best choice) or an i1Pro/i1Pro2 (more expensive, less accurate with GBLEDs but can profile printers)

  55. December 8, 2014 at 4:25 pm

    >>Out of all the modes listed above, the “Native” mode will give you the most number of colors, so I would recommend to start with that one.

    What, most number of colors? You mean a larger color gamut. Same number of colors (and a lot of device colors we can’t see).

    • 55.1) Richard Lundberg
      December 8, 2014 at 9:59 pm

      The U2413 does not have Native. You have to chooses 6500 as a best guess from the monitor temperature selection.
      I am awaiting the result of coordination between XRite and Dell regarding the statement in the readme file for the Mac version of the Dell UltraSharp Calibration Solution ver 1.5.3 that says “some Mac video cards may crash and not reboot”. Probably the least informative statement I have ever seen in a readme.
      Dell tech support is impossible. I always get someone who doesn’t know they make monitors, doesn’t know they support Mac, and won’t get me a case number. Bruce Wright of XRite asks me to try them again and if I could not get anywhere to tell him about it and he would have the XRite Dell liaison guy deal with it. Should be this week.

        December 9, 2014 at 8:45 am

        Richard, even if the U2413 has no such native mode (and it should), the article is incorrect and confusing when specifying “Native” mode will give you the most number of colors“ that’s not the case. The gamut of a device is the range of colors, not the number of colors it can reproduce. The display in sRGB or wide gamut mode produce the same number of colors, but the gamut is of course different. Then there’s the fact that the encoding of values (e.g. 3 to the 8th to produce 16.7 million colors) is just that, math without reality. We can’t see anything close to 16.7 million colors. But we can produce 16.7 million device values which isn’t the same! The same encoding of values will produce the same number, hopefully we’re talking about colors not numbers because if you can’t see a device value compared to it’s neighbor those two ARE the same colors. Color is something we perceive. The manufacturers of displays love to tell us how they can produce billions of colors but that’s simply not the case. They produce billions of device color values, that’s not the same. It’s mostly marketing hype (number of colors).

        As for the correct CCT or Standard Illuminant, YMMV, there is no correct number EXCEPT the calibration aim point that produces a match to a print (assuming that’s your goal), same with the backlight intensity (cd/m2):

    I just purchased the U2413. I have been impressed with the AdobeRGB gamut support. What is a big problem is Black Levels. Anything below 20 in the range 0 to 255 resolves solid black. The Uncalibrated Black Point seems to be around 0.23 cd measured with monitor brightness at 22% and contrast at 50% – I like to work at 110 cd/m2 and use hardware adjustment
    for brightness. I have tried Calibrating with custom RGB settings (98,94,100) and the AdobeRGB mode (results below) but the Black Levels remain much worse than any of my other cheaper U series monitors such as the U2311H and 2209 WA. Whereas I do not mind the black point being a little high, not being able to resolve Black Levels is annoying.
    For those that use the U2413, what has been your experience with resolving Black Levels on a gradient?

My self, I have given up on calibrating the U2413, packed away my i1 Display Pro and am using the factory aRGB. I have emailed Bruce Wright at XRite several times about the Dell Readme in the 1.5.6 version of the DUCCS that says “Some Macs may crash and the only way to recover is to use another monitor to reboot”.

            It looks like I am lucky!
            I found this web page: I downloaded the embedded image, converted into TIFF and displayed it with Lightroom.
            With my monitor set to AdobeRGB mode (factory calibration) I can distinguish the top row up to patch 2 with brightness set to 50. Patch 2 becomes black when I reduce to 25.
            With color-managed Picasa I can distinguish patch 1 as well.
            (With non-color managed software I am not able to distinguish the top row.)
            So it looks like my video card is in 0-255 mode!

            I haven’t calibrated the monitor so far: I am using factory calibration. I’d like to use AdobeRGB mode. Is the following setup sensible?
            1. Set monitor to AdobeRGB (Preset Modes->Color Space->AdobeRGB)

I want to calibrate/profile my monitor with CAL1 set to native and CAL2 to sRGB. I am fairly new to this and have a question about the calibration instructions in the article. I think I understand things up to the point of saving the icc profile, but am confused about whether there needs to be a separate icc profile for native and a different one for sRGB. The article is confusing to me in that the example uses “DELL U2413 (Left).icm” as an example file, implying to me the same file for both CAL1 and CAL2. I would think there should be a different one for each calibration. And if so, do I need to manually load the different profiles in the Windows operating system or does the Dell software or on screen display buttons take care of this automatically when switching from CAL1 to CAL2? I guess my understanding of this process is still somewhat limited and the Dell documentation very poor.
    Thank you for your help.

      ICM profiles generated with DCCS only contain “display behaviour” and linear LUT for your GPU to clean previous lut calibration (sinec calibration is stored in monitor).
      Color managed apps NEED to know what is cthe CURRENT state of the monitor (gamut, gamma, white =behaviour) so if you are going to use color managed apps EACH TIME you switch OSD mode, you should switch in yoir OS control panel > color management the profile that matches that monitor mode (so colro managed apps know what is the actual monitor behaviur).
      I think there was a trick on Windows regirstry to tweak Dell Display Managed to to the work for you, but is for advanced users as all registry tweaks. If switch with monitor OSD buttons, you should switch ICM manually.

        Thank you very much for this explanation. It makes perfect sense and is the way I am doing it. One question, however, is that if I only change the display using the OSD and not the ICM in the operating system, I can see a difference, but then when I change the ICM in the operating system, I have a hard time seeing much of a difference than if I leave it to the same profile.

        • ColorConsultant
          February 15, 2015 at 6:10 am

          The latter situation (OSD change, no ICM chaned) makes sense for Color managed apps. Since Windows desktop or other apps are not color managed, no color drift when changing a “NON” calibration profile (linear GPU LUTs)
          When you have CAL1_adobeRGB.icm and switch from CAL1 to CAL2 (srgb) gamut lowers in green side (which “perciable color gamut reduction” is less than xy diagram “area” reduction, xy diagram is not a perceptually uniform one (look at , ellipses’ areas are “equal” to your eyes)
          Hence “desaturation” is less observable

    I will get my UP2414Q on tuesday and have only Colormunki + DispCal at the moment, what are the best Dispcal and monitor settings to calibrate and profile? And if I get 1i Display Pro? E.g. Can you calibrate with Uniformity Compensativo On? Manual seems to advise not to use it in Cal1 and 2?

      February 15, 2015 at 6:19 am

      Munki display has the same accuracy than i1Displaypro, but with a Munki you won’t be able to hardware calibrate monitors (Dell, NEC, Eizo..) And it is much much slower.
      DispcalGUI calibrations are GPU calibrations, hence if you di not have a nvidia Quadro GPU or an AMD GPU (gamer or pro) you’ll get HORRIBLE banding in widegamut modes.
      So, your options (if abobe requirements are not met):
      -get an i1DisplayPro
      -get an AMD/ATI graphics card (or a newer Quadro)
      -get both, best advice: you get HW calibration plus L* gammas without banding.

      Operation in DispcalGUI is the same from Munki Duisplay and i1DisplayPro:
      -choose white, better choose luminance manually (set white level to native and lower brightness manually when fixing WP in RGB gains on OSD), choose gamma
      -select a XYZLUT profile (600 patches or more…. not a sensible choice your very slow decices like yor Munki) or a curves+matrix profile.

    If one already had an i1 Display 2 and could not purchase both U2713H and a i1 Display Pro which is the better alternative: (1) the U2713H alone recognizing the calibration may not be as good as using the LUT approach, yet wondering how significant the difference would be, or (2) a different monitor that didn’t require the i1 Display Pro. Application is Lightroom primarily and some Photoshop?

      DO NOT GET a widegamut without a colorimeter (“non lab” one, I mean) that supports spectral corrections (Spyder4,munki Display, i1DisplayPro), and your own sake get an i1DisplayPro without doubt).
      DO NOT GET a LED monitor (which includes GBLED widegamuts and WLED sRGB monitors) without the same.

      Best advice is to sell (or forget in a drawer) that poor performer colorimeter. Get an i1DisplayPro or (you ‘ll not HW calibrete monitors) a Munki Display. With the money you have after purchasing one of these, get the best monitor you can for your money (widegamut or sRGB)

      IT IS POINTLESS to calibrate with a device which readings are not reliable at all with a LED monitor.

    I purchased new Dell U3014 and am currently trying to calibrate it with x-rite i1 Display and Dell’s own “Dell Ultrasharp calibration solution” software. The calibration process as such looks to be working just fine. My problem is that the device should actually also be able to run all the time and sensor the ambient light while I am working on my computer and perform some action when light conditions change. But this is never happening. The device is always off and there is also no utility running in desktop’s taskbar. Do you guys have any idea if it is possible with this Dell’s own software to use this functionality to monitor the ambient light throughout the day?

    My second question is regarding the actual ICC profiles which are created by the calibration software.
    In the article it is mentioned that I must remove all ICC profiles from Color Management in Windows Control Panel. I did it before calibration. Then I calibrated the monitor and created two profiles, one for AdobeRGB, the other one for sRGB. After the calibration these profiles do not appear in this windows color management settings. I mean, they are listed among other profiles under “All Profiles” tab, but they are not assigned to my Dell monitor under Devices tab. Is this OK, or should I actually attach both new profiles to my “device” under Devices tab?

      No ambient light function, not a useful feature either. Change brightness > WP may drift, so it must be avoided. Change whitepoint? > LUT3D recalculation an rewriting it to monitor and PROFILE again.
      So “Continuous ambient light measurement” IS NOT a useful feature, has more drawbacks than most users think. BTW AFAIK no ambient light measurement with DCCS even at calibration time (which could be useful)

      I asume you use Windows : Control panel> color management>devices, your device, check “use my configuration…”, then “Add” and Add the profile. BTW, DCCS should to this stuff auto after profile is wrote at th end of the process.

      • 61.1.1) Martin
        February 24, 2015 at 3:08 pm

        Thanks for the answer ColorConsultant.
        You’ve got the point, the ambient light measurement is a no go, I won’t miss it.

        But I am still struggling with the other part. I don’t understand how the calibration is applied. Does the DCCS actually writes something directly to the monitor? Is this LUT table written directly to the monitor? Because even after the calibration is complete I don’t see any profiles automatically assigned to my Monitor in Control Panel>color management>Devices. The checkbox “use my configuration…” is checked.

        Maybe a simple use case would help me to understand, I’ll try it, please correct me if I am wrong.

        I am using Windows and editing my RAW photos in Photoshop while I want to publish them on the web as well as print them.
        This means I want the best possible quality for editing.
        I do my color calibration with DCCS for two custom presets: Cus1 for AdobeRGB and Cus2 for sRGB.
        I assign both created ICC profiles to my “device” in control panel>color management>device and check the checkbox “use my configuration…”
        I am now about to edit a photo… I set my monitor to Cus1 for AdobeRGB, I set my working space in photoshop to AdobeRGB and open up my photo in CameraRaw in AdobeRGB. So I edit my photo fully in AdobeRGB. When I save the finished edit as a TIFF I can later get it printed in AdobeRGB space.
        If I want to publish this photo on the web, I need change the working space in photoshop to sRGB, change my monitor to Cus2 for sRGB and convert the photo to sRGB in photoshop. But this will kind of destroy the colors, so I have to readjust them and then save for web..
        And all the time I am not working in photoshop, but only surfing the web, I need to run my monitor on Cus2 for sRGB, otherwise the colors in the web browser would look different.

        Is this assumption correct or am I missing something here?
        I mean, this kind of “workflow” was not covered in the article, I am pretty sure most people do not use their computers and monitors only for photoshop work, but they also use it for daily stuff on the Internet, etc.. so knowing when and how to switch between the color spaces is crucial.

        Thanks in advance.

          February 25, 2015 at 9:27 am

          LUT3D calibration is written to monitor for sure. ICM /ICC profile stored on computer contains the achieved behaviour after calibration, so color managed apps will know what corrections to apply.
          The issue that you report…maybe, after calibration (LUT3D) and behaviour measurement (there is a camncel button below when doing this part), you did not click on “Next” when screen goes back to DCCS window. This is when ICM profile is created (there is a textfield woth Filename).

          Regarding your best workflow:

          -if you want to publish them in web (sRGB profile in the image) you do not need to “switch” monitor to a sRGB hardware emulation. PS or GIMP are color managed, so they will render properly an sRGB image in a properly calibrated and profiled CAL1=AdobeRGB. If you want to “test” that web page with your work, unless you use tagged images (embeded profile) or use Firefox, you should swicth to an sRGB emulation, like for example CAL2.

          -first of all when working with color managed apps is to make sure that your OS color management configuration matches monitor’s OSD mode. So if you are in CAL1=AdobeRGB, you must set (if not set previously) in your OS “CAL1.icm” (or a name of your choose) as default profile. Then open PS or LR. OS default profile must match current monitor behavior (OSD mode) BEFORE opening LR or PS.

          -After you did your work with the image (and AdobeRGB embebed profile image), if you wish to publish it for web: a ) convert it to sRGB profile, then save JPG and embed profile, this will not erase metadata, or b ) export for web, better to select embed sRGB profile, and if you wish to errase metadata and preview various quality compresion options for jpg. No need to switch to CAL2.

          -remember that DCCS “matrix profile” are unrealistic, they store info like monitor was perfectly neutral after calibration, but DCCS at its current state cannot guarantee that. Remember also that DCCS table based profiles for monitor are not understood by current windows versions of Firefox, Chrome, Opera… There is an option to “reprofile”, without recalibrate in DispcalGUI. Just select proper spectral correction for GB-LED (RG_phosphor) and make a curves+matrix or XYZLUT+matrix profile pressing “profile only”. Curves is faster because it needs less patches, but a little accuracy is lost. Photoshop understads table based profiles from DCCS without issue.

          As summary:
          > you can do ALL your work under CAL1=AdobeRGB: open raw image to AdobeRGB PSD, save it for print, then “covert profile to sRGB+save as” or “export to web” a JPG for web publish purposes.
          > If CAL2=sRGB, you can switch ot it to view JPG image in non color managed web browsers. Set OS defaukt monitor profile to “CAL2.icm” to use color managed web browsers, BUT it can also be done in CAL1=AdobeRGB with OS (or browser) default profile to “dispcalGUI_profile_only_CAL2.icm”. The easiest way is just switch all to CAL2 if you are not confortable dealing with all this color management stuff.

            @ColorConsultant, thanks a lot for this further info, though it took me a while to absorb and understand it, at least I hope I understand it a bit better now.

            So this is my take on the whole story. Would you please correct me if I’m still missing something?

            The basics, what I need to do before anything else:

            – calibrate monitors’ CAL1 to adobeRGB and create a windows profile CAL1_adobeRGB.icc
            – calibrate monitors’ CAL2 to sRGB and create a windows profile CAL2_sRGB.icc
            – set photoshop working space to adobeRGB

            When editing photos:
            – monitor set to CAL1 – adobeRGB
            – CAL1_adobeRGB.icc set as default monitor profile in windows control panel->color management
            – in Photoshop, open RAW file from Camera Raw as adobeRGB 16bit image
            – which means, perform all editing in adobeRGB color space, 16bit
            – “save as” the final image as e.g. 16bit TIFF (adobeRGB) for printing
            – “save for web” the final image as 8bit JPG (sRGB) for publishing on the web

            When I am done with photo editing in Photoshop and I need my computer for daily work, Internet browsing, etc… then I have basically following two options:

            – keep monitor on CAL1 – adobeRGB
            – keep windows OS to profile CAL1_adobeRGB.icc
            – use color managed browser (Firefox) and color managed image viewer (irfanView)
            – get used to live with oversaturated jpg thumbnails in file explorer and desktop wallpapers (because they are sRGB and I am running adobeRGB across the system and windows is not color managed)
            – get used to live with oversaturated colors in PDFs, MS Word and other documents, basically in whole windows environment

            – change monitor to CAL2 – sRGB
            – change windows OS to profile CAL2_sRGB.icc
            – then any browser will show correct colors for JPGs on the web
            – desktop wallpaper, JPG thumbnails, all correct in colors, PDF and other documents in correct colors
            – only TIFF (adobeRGB) thumbnails in file explorer undersaturated

            Am I getting there? :-)

              February 28, 2015 at 1:22 pm

              1) Need a profile made by DispcalGUI for Firefox. Table profiles from DCCS are not understood by any Windows browser, matrix profiles by DCCS are inacurate ones and shoudl be avoided. DispcalGUI profiles without calibration are done by pressing “profile only”. Remember that GB-LED spectral correction must be set prior to measurements (RG_phosphor EDR/CCSS) in DispcalGUI.
              And AFAIK, Infranview IS NOT color managed. Windows image viewer (w7 onwards?) understands properly DCCS profiles, DiapcalGUI matrix profile and “matrix” from XYZLUT+matrix, so Windows image viewer (while not in full screen mode, full screen=current calibration native gamut and gamma withot color management) is color managed and works out of the box.

              The other topics are OK ;)

                Ah ok, the thing with Firefox, I just did not understand it correctly from previous posts apparently.
                The DispcalGUI.. I think it’s a lot of hassle to only have a browser color managed while all the other stuff in Windows will still be shifted.

                I think I will stick to my 2. option.. simply work with sRGB acorss the whole system/monitor for most of the time and switch my monitor to adobeRGB and windows color management as well to adobeRGB ONLY when working in photoshop. Now I at least now how to properly do it :)

                Once again, really thank you for the great help! I think you should put together some short article “color management for dummies”, while your knowledge about this topic is fabulous, and it would surely help lot of people ;-) cheers!

        March 12, 2015 at 7:06 am

        U2413 + DCCS have a “Native” preset when choosing calibration target fro CAL1 or CAL2. So in this case missinformation or lack of knowledge come from your comment.
        If you were talking about native gamut, “standard” and “Custom” modes have it.
        So please try to avoid posting false facts.

        The only way to hardware calibarte these “not 4k” GBLED with an Apple computer is to do it in Windows (in that Apple computer or a PC), unless DCCS 1.5.7 (UP2715K release) is able to hardware calibrate these Dells (U1413,U2713H, U3014).

          After reading a few of your mostly overly long responses, many of which seem to be promoting AMD graphics cards, I am inclined not to listen to you. For one thing I have used BOTH NVidia and AMD cards, I have found that based on the specific software I use for Photography, the AMD card is inferior. That is not AMD’s fault, but it is a fact. Properly calibrating a monitor I have never had banding with either card and I have used both.
          Even if you are correct with part of what you say, you indeed are writing in a manner that is overly complex for somebody that does not know what they are doing and you seem to want to fool as many as you can and try to impress.
          One thing I have found in my own learning of color management is that so-called experts or alleged experts, all seem to have different opinions on color management theory, many of which differ.
          The bottom line is this, I advise those with questions to trust X-rite Support, before trusting you. I have had enough discussions with them over the years to know they know what they are talking about.
          If you really are a qualified Color consultant, you would not be afraid to at least provide a last or first name; I understand most not providing their name, but when you promote yourself as a expert, then surely you are well known.

            I do not need to impress you, I just need to expose your false claims trying to confuse audience.

            *IF calibrating using GPU LUTs*, not monitor internal LUTs in their hardware calibration “slots/presets”, unless you have a *Quadro* or an AMD you’ll get banding on ALL DIGITAL oputputs.
            It’s a FACT, and it can be tested with ArgyllCMS (which is FREE): uncalibrated screen report.
            You need more than 8bit per LUT entry if you do not want that rounding errors arise.

            AMD high bitdepth LUTs works in the same way that internal HW calibration: temporal dithering. It means, to translate to temporal domain the lack of resolution of your actual channel.
            For example in an Eizo/NEC /Dell using HW calibration it is used to go from 14bit correction stored in monitor’s LUT, to 10bit panel input, to 8bit actual panel bitdepth. Or in GPU LUT calibration to go from 12bit correction (LUTs) to 8bit DVI output, as an example. On non Quadro nvidias you are limited to 8bit correction…

            So please, educate yourself before posting nonsense and confusing users.

    Hi, is there a way to set contrast ratio on U2413 as a part of calibration process to match that of gloss or matt photo paper?

    • 64.1) ColorConsultant
      March 25, 2015 at 7:35 am

      Not if calibrating internal LUT3D (Dell color calibration solution), that could be done with GPU calibration like with other monitors (DispcalGUI, I1Profiler, Basiccolor..).
      Keep in mind the drawbacks of your “low contrast target”: if not done properly, it will be done at the cost of avaliable grey levels. In order to minimize this, make sure that using contrast, and brightness OSD controls you get a little more contrast ratio than you wanted, then try to fix with RGB offset OSD controls the black point while keeping track of contrast. That kind of infromation is reported in “i” button on DispcalGUI while you are on “white point correction popup” (the one with 3 RGB sliders).

    Hi, I have a U2413 hooked to a Mac. Dell’s software only appears to be for Windows. Has anyone successfully hardware calibrated their monitor using a mac? How did you do so?

    If I can’t, would using a spyder express give me a close software approximation?

    • 65.1) ColorConsultant
      June 3, 2015 at 9:59 am

      You can calibrate ANY monitor in your graphics card LUT. Just use ArgyllCMS/DispcalGUI or i1Profiler (which is worse)

      Dell software (DCCS) is for calibrating internal lut inside your U2413. DCCS is for windows, and only if you have a 4k GB-LED dell (which you don’t have) there is an OSX version of DCCS.

      Therefore, there is no need to use Spyder express or other bad performer device if you have an i1Displaypro.

      Keep in mind that ANY monitor that is calibrated in graphics card LUT will show banding unless it is driver directly form an AMD/ATI graphics card or a nvidia Quadro.

      If your mac (or PC) computer does not have this kind of grahics card is not (and will NOT be) suitable for proper calibration of monitor… unless you own a monitor with internal calibration and you are able to run it.

      Intel HD, Intel Iris, nvidias GTX… all unsuitable for proper calibration using graphics card LUT.

      You have three options, not exclusive:

      -install Windows in dual boot, not paralells, no virtual machines. Windows must run directly on your mac. Then calibrate CAL1 or CAL2 on your Dell with DCCS. Save 2 icm files in some portable storage. Go back yo OSX and install profiles. Swicth OSD modes to CAL1 or CAL2 (must match active monitor profile). This option is the easiest.

      -Get a proper computer for photo work: a PC, Windows, AMD Firepro or nvidia Quadro… not a Mac

      -return your Dell and get an Eizo CS240. It’s +50% more expensive but “affordable” and it has OSX support for internal monitor calibration (ColorNavigator6, CN6). CN6 may have some issues missing the aim for white point due to outdated xrite SDK libraries. NEC spectraprofiler/basiccolor display approach is better IMO, it’s software ask user to choose proper spectral corrections for colorimeter (RG_phosphor). Although it may confuse non experienced users, that allows you a way to ensure proper correction is applied.

          After six months of sporadic communications with Bruce Wright of X-Rite and two recent emails from Juven Garcia of Dell tech support, I have this to report:

          Customer Communication


          Thanks for your

          I confirmed
          with our development engineers the read me file alluded
          specifically to the older Mac OS 10.6 and 10.7 where crashes
          could occur.

          The many
          variables of graphic solutions along with displays made it
          difficult to specifically spell out which configurations
          would cause crashes.

          The newer OS
          versions 10.8, 10.9 and 10.10 all work fine and you should
          not have any crash issues with any display.

          The new OS
          corrected the communication issues with graphic solutions
          which would result in crashes present in older OS.

          You have the OS
          10.9.5 which should be fine for you to use the DCCS and
          U2413 display.

          The problem was that the read me for the Mac OS version of the DCCS said that “some Macs will experience an unrecoverable crash requiring a second monitor to restart”. Dell has apparently pinned down the problem to OS 10.6 manx 10.7.
          I still haven’t dug out my X-Rite Display Pro to do an internal LUT cal. One reason is that the Mac output is limited to 8 bit, the U2413 is 8bit +FRC, and i can’t quite see the efficacy of inserting 8 bit interpolations into a 14bit curve. The second reason is that a member of the CiC forum is doing a LUT cal and I haven;t heard from him yet. The third reason is that the factory a RGB looks pretty good and I’m not sure how I would know that the multiply interpolated U 2413 would look any better without a spectrophotometer measurement from a lab?

            NEC, Eizo and all those non-32″ GB-LED on the market are 8+FRC.
            Dithering (FRC) is what allows an AMD graphics cards to calibrate ANY MONITOR without banding, it’s akin to a 12bit LUT1D processing.
            Dell, NEC, Eizo hardware calibration makes 12-16bit DITHERING to 10-bit panel (this is what internal or factory calibration does), then the panel dithers 10bit input to 8bit.
            What you said (8bit+FRC, or 14bit processing to 10bit panel) IS DITHERING, not interpolation.

            Interpolation IS NOT what you meant. Interpolation means calibration calculations from limited amount of points/measurements, for example 17 for each black to R,G,B primaries because YOU CANNOT MEASURE ALL 16million colors even en 8bit to perform a LUT3D calibrations.
            Interpolation from a fine mesh of points is ENOUGH to perform a very good calibration (dE<1), the poorer the uniformity and native grey response, the more points you need. That's the main argument to blame Xrite & Dell, only 10-11 points per native R,G or B ramp in DCCS (plus other points in native gamut 3d mesh, like secondary ramps from black to secondary to white).

            96 grey ramp measurements performed by ArgyllCMS plus an AMD graphics card is what gives ArgyllCMS/DispcalGUI its superiority over ALL graphics card "LUT1D" calibration software (Basiccolor and i1Profile included). Those 96/256 grey ramps in an AMD should be enough to calibrate even lowcost 21-23" IPS monitors, even with blocked controls from sRGB/AdobeRGB factory modes which means less unique RGB values after calibration.

            What you say about factory calibrations is a nonsense… which comes from a lack of knowledge in this matter. Dell says to you that your monitor has been calibrated in a fast way (number of measurements…) with a mean error less than some value. Do you know what a mean error is? Seek definition. Do you know that some (LOTS OF) values should be OVER actual mean value? Do you know that calibration ages because native response in monitor changes?

            To buy a widegamut and to not calibrate it is a complete NONSENSE.

            10bit/channel workflow is to ensure that color management does not pollute GPU output, for example while displaying an sRGB image in Photoshop in a Dell,Eizo,NEC hardware calibrated to its native gamut (so it can edit AdobeRGB images too). You cannot output all 256 reds or greens in an sRGB image, or 256 yellows if a widegmaut monitor is in its native gamut over 8bit connection.
            OSX has not that feature, it's an OS limitation from an OS not prepared to current state of the art of image editing. Mac Pros have AMD Firepros (10bit output, 12bit internal LUTs)… but no 10bit untill you move to Windows.

            10bit is to overcome limitations of color management, and to be able to input monitor 16bit/channel images almost unmodified.

            Current DCCS for OSX does not calibrate internal LUT non 4k GBLEDs. Do a try with ICC version2 DCCS calibration and profiling, then validate with ArgyllCMS/DispcalGUI. Inspect resulting profile: Which gamut? (if Color Sync does not mess around and broke everything, very bad OS…), does it alter GPU LUTs? which actual white dit it archieve?
            Do you want LUT3D calibration with all Dell's GB-LEDs?, then move to windows… or buy a PA NEC or CS240 (cheap!, give it a try), CX or CG Eizo which have.
            Or even better, both of them: Windows + NEC PA Spectraview : 10bit, internal calibration and Full LUT3D profile emulation (without color sync messing around and ruining everything)

            Please, educate yourself on these concepts before future post attempts with WRONG information.

              You do nothing to clarify this subject and constantly promote Windows. Therteare several interpolations in the chain of calbration using the DCCS on a Mac. Of course FRC is a form of dithering. The DCCS sends 30 bit color to a Mac which converts it to 24 bit by interpolation. this color is displayed as 8bit+FRC per channel. The i1 reads this and creates a 10 bit number to allow the DCCS to install it in one of the three LUT curves. If anyone can tell me what the result of all that is without sending the whole setup to a color lab, I’d like to know about. I’d appreciate jot if you would stop using thee words false, wrong and other annoying statements.

                No, you are wrong again because your lack of knowledge in this mmater, and the wost, you do not want to learn. You deny reality as many Apple lovers.

                You cannot send 30bit to a monitor with OSX.
                Even while calibrating a NEC or Eizo with have OSX hardware calibration support YOU DO NOT SEND 30bit data. You send LUT3D data (12, 14 or 16bit), full LUT3D for “profile emulation” or “input lut”, “matrix” and “output lut” for usual calibration.
                In DCCS you can even see the actual data sent in its log files. So your statements ARE WRONG.

                Even on a Windows system which is capable of true 30bit output, at the last stage, after internal calibration is applied, you have 30bit data which are fed to panel. A 8bit+FRC panel has 10bit input. In panel the transition from 30bit to 24bit IS NOT INTERPOLATION, it is dithering.

                Interpolation is performed for ANY MONITOR, even in the highest quality device you can buy right now, to infer native response from a limited amount of measurements. Read the definition of “interpolation”. You cannot measure 16M colors response, it will last too long, so you meaure black to R,G&B ramp; R,G&B to white, CMY form black and to white and several mid points to capture a mesh of native gamut response at a certain “density” of the mesh.

                The higher the mesh density, the better. Then ANY calibration program (even Eizo or NEC ones) asumes a smooth transtion between measures (taking acount of -2,-1 and +1, +2 neighbours in the mesh if needed). Interpolation is performed THERE.
                After monitor response has been captured (of infered by interpolation) correction is calculated (white, gamma, grey neutrality and gamut limitation).

                Monitor does not store 30bit data for calibration. It stores LUT 12-14-16bit data to prevent banding, and in LUT3D full 12-14-16bit x3 (36bit, 42bit or 48bit) output is interpolated from mesh for a particular 30bit input data.
                Then dithers these corrections to whatever native bitdepth monitor panel has. AND THIS WORKS.

                Please stop posting wrong information and your usual nonsense. Educate yourself in this matter, plenty of info in books or internet. Start with a basic maths book and look for “mean” and “interpolation” definitions.

    Nasim, I have Dell U2412M 24″ monitor. Will the same described procedure work?

      Your monitor has not internal hardware calibration writable by user.
      best chance is to use ArgyllCMS/DispcalGUI with an AMD graphics card
      (GPU). If works for all OSes: Win, Linux, OSX.. you can compile it if
      you wish.

      Calibration correction wil be computed on 3xLUT1D
      256x3x16bit and stored on a ICM profile (VCGT tag inside ICM file). When
      calibration is loaded into graphics card you’ll have 256x3x12bit data
      (if you own an AMD card, 256x3x8bit for intel or nvidia gamer card).
      each color fed to an AMD GPU, LUT outputs a 36bit pixel color info
      (12bitx3) whith is temporal dithered (with its time neighbours) to
      8x3bit data preventing banding. This 8bitx3 pixel color info is fed to
      your monitor.

      In your particular situation, as any monitors, it has 6bit/chanel panel. Monitor
      internaly will perform a dithering from 8bit x3 to 6bit x3.
