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.

      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?

        Or I miss something and don’t know how to do that.

        • July 16, 2014 at 7:36 pm

          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.

            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?

    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 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…

    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:

      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… :(

    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!

Alas, Typical apple, you get no idea whats going on, so in the meantime I’m looking at different monitors.

    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.

    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.

        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.

        -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?

          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:

      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.

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

    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)?

    • 59
      ) 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.

    ) 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?

      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.

        • August 4, 2014 at 10:56 pm

          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…

              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.

      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).

              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.

        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.

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!?

            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.

              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.

      -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.

    sRGB is the profile i wanna use when i color correct in after effects? The native sRGB my monitor offers is ok to use without calibration? Also when im working in sRGB should i set also each program’s color profile to sRGB?
    thank u

      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,

    Is there or is there not a Dell XRite Monitor Calibration Solution software package for the U2413 that runs on a Mac to do hardware LUT?
    I downloaded the only one I could find but it says it is for two other monitors with a Q designation.

      Non 4k GB-LED need to be calibrated in ms windows 7 or newer. You choosed the wrong OS to work in photography for several reasons. Windows and well choosed components in a PC superior by far to Apple computers and OSX

        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.

    There is much more to the calibration of this monitor than described, just read this post
    I hope you could add those steps into the article, and make it precise.

    Nasim has promised to revisit this whole calibration issue and bring some common sense to this overly technical jargon. Hopefully he will soon.
