HI, we are using also x-rite and colourspace beside of Displaycal. Usually it is recommended to deactivate first any existing ICC colormanagement before calibration. However, we have to calibrate several Surface Books 1-3 and there is no option to deactivate or temporarily delete all ICCs.
Thus, my question is: is there any “dummy null ICC” which would disable any color management by activating it?
Or how is Displaycal handling it? You then perform the calibration based on the current ICC e.g. sRGB, thus the gamut is already limited to this space giving probably not the best results.
Furthermore, you will get an ICC after calibration, which is based on the measurements another ICC is already active (e.g. sRGB), but that one will be replaced then be the new one created by displaycal. Thus, how displaycal is doing that, is it combining both ICCs at the end?
Is there any utility to concatenate/combine ICCs as with LUTs?
many thanks!!!
-Windows have no desktop color management so there is no “sRGB translation” based on profiles
-DisplayCAL cleans GPU grey calibration on new calibration (unless you explicitly say the opposite in “profile only ” scenario)
-if your GPU or laptop vendor has an application to emulate some smaller colorspace using GPU and EDID values, just set it to the value you want, then DisplayCAL on top of it to calibrate grey and make a profile. There is “no profile” involved here, just vendor or GPU driver colorspace emulation.
DisplayCAL profile will only be valid for THAT GPU driver/ laptop vendor setting. If you change laoptop emulation from sRGB to P3 using vendor app, you’ll need another DIsplayCAL profile. As you change form one vendor app screen mode to another ypu’ll have to reassign default display profile on OS settings (or faster: use DisplayCAL tray app)
