Grayscale colors too bright on Linux with my monitor Benq EW2775ZH

Especially visible on webpages. Same with Firefox and Chromium. Grays are too bright in comparison with other colors (reds, greens, blues). Sometimes I cannot see buttons and borders when they are made with light-gray color. Problem exist only with Linux on my monitor Benq EW2775ZH and Nvidia card (1050Ti). Problem not appears:

  • on Windows
  • on Intel iGPU on Lniux
  • on different monitor on Linux and Nvidia

I’m using manjaro linux but I have tried other live distros and problem exit too

I added log file to my first post.

All settings look normal. Did you check if your DE loads the wrong color profile or change it?

I don’t think it’s DE relevant problem because I have tried different live distros with different DEs. Always the same effect. It’s very strange problem because only shades of gray are affected and other colors are properly displayed. When I change monitor or card to iGPU problem disappears.

Nevertheless, did you check if different color profiles are being used?

Yes indeed it was faulty default icc profile. I found this blog: https://fatminmin.com/blog/benq-ew2755zh-icc-profile.html
and used new icc profile. Now colors look better. Thank you for the idea. Problem solved.

You should report that to freedesktop.org or your ditro’s bug-tracker so other users don’t run into the same problem in future.
