Just looking at my new iMac was giving me a headache: the "Retina" display was so high-contrast, even at the lowest contrast setting, that it was searing my retinas.

Is there a way to reduce the contrast past the lowest keyboard setting?

Yes - by using display profiles, you can alter what absolute values the relative 100% and 0% contrast settings are. You don’t even need calibration hardware, but sometimes that helps you dial this in precisely.

  • Go to the "Color" tab of the "Display" panel of System Preferences
  • Select the display profiles, one by one to see which you prefer.

When I got to "SMPTE RP 431-2-2007-DCI (P3)," I hit PAYDIRT: contrast and saturation were down to something I could easily live with.
