Steam seems to limit my resolution to 1080p while my desktop is recognized as 4K

I did my first install on my HTPC with HTPC bazzite no big picture ISO. I have an AMD CPU & GPU. I tried 2 different games, my max resolution is limited to 1080p while I'm on a 4K screen. I did a steam system report and there is one line : "Bazzite steam[2857] : Deskstop state changed desktop {pos : 0, 0 size 1920,1080} primary {pos 0, 0 size 1920, 1080} So I tried in steam big picture to change the resolution setting for one game : I tried : - Native : still limited to 1080p - 3840:2160 : still limited to 1080p If someone have any idea ? Happy holiday !

under settings -> display -> advanced there is a setting "Maximum Game Resolution", is that set to something?

In steam big picture mode under setting -> display-> advanced I only see "disable GPU blocklist" I tried elden ring & sekiro in fullscreen & windows mode I'm limited to 1080p no matter what I put in the app option in armored core 6 & elden ring , in fullscrren & windows I'm limited to 1080p but in borderless windows I can go to any resolution. i also tried to put in the argument “ -screen-width 3840 -screen-height 2160 ” (without the quotation marks). didn't work I got a KDE update that fix the issue. I tested a couple of game everything was fine. I rebooted the computer; the issue is back again with my resolution being limited to 1080p
