Description fililip 2026-01-06 19:19:20 UTC

There is no way to set an ICC profile for a display when HDR is enabled. A display with broken/overrepresented built-in color primaries in its EDID will show desaturated sRGB content vs. a properly factory-calibrated OLED panel if the sRGB intensity slider is set to 0%. Similar desaturation is observed by setting 'Built-in' as the color profile option, but for non-HDR workflows there is a way to set an ICC profile.

Could you attach an ICC profile for an HDR screen here? I could use one for testing.

A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/8613

I don't have a colorimeter (yet), so I'm not sure how I can obtain a profile for the primary-overrepresented IPS display that I have right now, is there an alternative way to get it (i.e. by somehow extracting what KWin uses for the "built-in" profile)?
