![]() Maximum widen color coordinates a display can show (the most satrated colors)= Primaries (determined by LED backlight technology). but CIE XYZ color coordinates for R G and B primaries (255 on primary, 0 on the other two) is determined by LED + phosphor technology used in LED backlight. That's all.įactory calibration may be low QC and white may not be D65 (use RGB GAIN in Custom mode) and maybe gamma is not exactly 2.2. Default displa圜AL configuration for macos account this, use that.ĭriver ICC is just a "generic" description about how a model is: D65 white, 2.2 or sRGB gamma and position of native primaries R, G & B. If you want more accuracy, make one with a colorimeter, but keep in mide the huge limitations of poor color management on MacOS, these profiles need to be "simple" (matrix, 1TRC, infinite contrast even it's fake) not "detailed", otherwise mac won't recognize them in apps that use Apple color management or show artifacts. Each tiem you change OSD mode you go to Color management configuration on your OS and switch default ICC profile for display. If you use other OSD preset with full native gamut use the one provided by Dell. You you trust on factory sRGB calibration use sRGB profile for sRGB mode. Copy Dell driver ICC/ICM from a Windows computer to your mac and associate it manually.Īnd do not clone screens, use extended desktop if you are on a mac/win laptop.Įach OSD preset needs an ICC to be active as default display perofile when you switch OSD mode. It should be detected by EDID and OS make it on 1st connect but. You need to ensure that default ICC associated to your dell display on Mac is the good one. RGB gains on nvidia control panel have no effects on saturation (only white color), you'll need an AMD card for simulating sRGB, or a full LUT3D in software for windows like in madVR compatible vidoe players, or an ICC awara epplication like MS Edge or Photoshop. sRGB mode must be used with sRGB profile as display profile or a custom profile. If you switch to sRGB mode but keep default profile, all will look undersaturated on color managed software (that includes MacOS desktop). Same for auto generated ICC profile in mac which has color management at desktop level. Driver profile (not a custom one made by colorimeter) = native gamut (standard and custom mode for dell). Profile only is valid for the OSD preset it was made. What you see is apps that do not have color management, thus they ignore ICC profile even installed. It is bundled with dell driver for your monitor, or made custom. No, ICC is not a "monitor property", it's software describing how a display behaves. You can see how your current display or U2515H will behave (on paper), just extract driver EXE with 7zip or winrar and you'll get ICM/ICC. Run command line (of course with DIsplaycal as current folder or in $PATH):ĭispla圜AL-profile-info.exe "YOUR_DISPLAY_Profile_FILE_PATH" ![]() You can use Displa圜AL profile info viewer to see gamut boundaries and compare them to sRGB. Learn about profiles & colorspaces first. nvidias don't have this feature in control panel.ĭMW LUT, LUT3D on GPU, can run in any moder GPU, including integrated ones, so GPU vendor is no issue.īut this is a rabbit hole to do not go unless you have basic knowledge of color management. cube with DMWlut, assign in OS "sRGB" as display profile and your games will look like in an sRGB display.ĪMD GPUs can do something close on AMD control panel, but locked to sRGB (while these custom LUT3D can simulate mobiles and tablets too). Make a IRIDAS lut3d, source colorpsace is the space you want to simulate (sRGB) and destination colorspace is an ICC that describes your display (native gamut). Then on Displa圜AL there is a standalone LUT3D maker app. ![]() It's called DWM LUT and needs to be compiled (MSYS + Visual Studio, or ask developer for a binary). It is possible with a new LUT3D runing on pixel shaders on GPU.
