General system Kernel, boot, graphics & hardware

Hello, I just upgraded from rx580 to rx 6700 xt, but my displayport monitor can´t run on native resolution (“out of range”) only smalled ones
Programs like discord a steam randomly crashes and when I start some games I get blackscreen. Only games that worked for me were Control (but without ray tracing support), Deadlock and openttd.

I tried reinstalling mesa with pacman -Syu mesa, other versions of proton but nothing helps

Have you tried disabling freesync?

3

I turned if off on main monitor settings but nothing changes. programs and games still crashes and second monitor still can´t do native resolution

4

Did you turn it off on both monitors settings.

5

second monitor is old (the one what is out of range), it does not have freesync. I previously connected it with DVI but now I use Display Port

8 hours of bad sleep later, games started to somehow work. But monitor still don’t work in native resolution
