           Summary: Refresh rate and HDR breaks when I restarted my TV

      Version First 6.6.5
       Reported In:
          Platform: Bazzite
                OS: Linux
            Status: REPORTED

  Target Milestone: ---

I had to restart my TV due to a audio bug. And after the TV came back, kscreen
decided to put my secondary TV as Primary. So I switch it back. Now I get only
30 Hz and no HDR. All on my 1080 Ti.

If I use my AMD iGPU I get 60 Hz but no HDR. Had it before.

All of this worked fine before my TV restart. I had 60 Hz and HDR for months.

Just to note I had same problems with Windows 11. Is this NVIDIA display driver
issues?

DESCRIPTION


STEPS TO REPRODUCE
1. Restart TV. AKA Same as unplugging the HDMI from TV.
2. Kscreen puts my secondary TV as prime TV and Primary TV goes into 30 Hz and
HDR is missing from Kscreen.
3. I change the Primary TV back Primary and that's it.
4. Restarting PC does nothing.
