resolution and refreshrate capped in KDE settings
Hi ! I just installed bazzite (kde) with the latest image.
I have a 5120x1440 240Hz display, but the highest resolution KDE offers is 3840x1080. I also only have 120Hz available.

basically, AMD does the display protocol in the open source driver, but the hdmi forum doesn't want to allow that. therefore AMD isn't allowed to implement HDMI 2.x on linux.

what connection are you using? HDMI or DisplayPort?
Hdmi, 2.0 or 2.1 i think @termdisc (Deck+PC)
Hunh, it works on DP1.2
I don't get why it dosn't work on hdmi tho
Sadly DP1.2 requires DSC, so i'd prefer avoiding it
what gpu do you use? Did it work before changing to bazzite?
Asrock rx7900xtx
it's a new build, never tested it on another OS (i'll set up dual boot soon tho)
ah a AMD GPU, I remember, that AMD sadly has a licensing issue with hdmi 2.1
