+Troubleshoot conflicts with Graphic Card/VideoLUTs or quality - MacOS 10.x

On MacOS 10.X conflicts with Graphic Cards are recognized quite rarely, however, if you face issues with the resulting calibration quality, verify these Presets:

  • Turn off the Auto-Brightness-Adjustment in System Preferences -> Displays. This feature is present for Mac Laptop Displays with a built-in camera.
  • Make sure, that the Contrast slider is set to ‘Normal’ (left position) in System Preferences -> Universal Access. Do never apply this option within a monitor calibration procedure.
  • Turn off the option ‘Translucent Menu Bar’ in System Preferences -> Desktop&Appearance.
  • Turn off the Energy Saving options for Laptop Displays in System Preferences -> Energy


If these presets do not solve your issue, please do the following in exactly this order:

  • Quit i1Profiler if it is running
  • Open your computer’s System Preferences
  • Click on “Displays”.
  • For the display you are trying to profile, click on “Color” tab
  • Uncheck the “Show profiles for this display only” option
  • Find a profile called “DisplayProfile_Linear.icc” in the profile list and copy to your /Library/ColorSync/Profiles folder.  If the linear profile is missing, control click the application icon and select "Show package contents".  The linear profile is stored in the "Contents > "Resources" folder (ColorMunki Display) or the "Contents" > "MacOS" > "Profiles" folder (i1Profiler) in the application’s package. 
  • Click on this profile (the LUTs should change, because they are set to linear now)
  • Close the System Preference window
  • Connect your i1Display Pro and launch i1Profiler.
  • Select “Basic” mode and then choose “Display Profiling”.
  • Set Display Technology type to correct setting for your display (i.e. CCFL”, “White LED”), D65 whitepoint, and 120 for luminance.
  • Uncheck Enable Ambient Light Smart Control.
  • Uncheck both “ADC” and “Adjust brightness manually” in the Measurement step.
  • Build a new display profile for that display

Repeat this procedure at least once more and then build a new display profile using whatever settings that you previously used.
