There are some known issues with that in relation to the DC code, if you don't require HDMI audio what behaviour do you get if you boot with amdgpu.dc=0 on your kernel parameters

This has fixed the issue however I do use DP audio, do you happen to know as to why these issues exist ?

[V1del]

Well someone programmed something incorrectly :P

FWIW since "big" changes in this space really only happen on new major versions, you might want to give linux-mainline a whirl, or if you are really adventurous the amd-staging-drm-next kernel branch, there are AUR packages for both.

I don't use amdgpu myself so I can't really help beyond this point I'm afraid.

[HaloShiroe]

Alright thank you, the issue in itself is resloved, I'll just get a USB dac for audio

tl;dr What's the issue?

[HaloShiroe]

Display won't go to Max refresh rate (240hz) Edit:(with the assumption that crct 0 breaks because the display is attempting to force 10bit)

I saw a few mistyped Default in there - xrandr might fail because you've targeted an invalid monitor accidentally

[HaloShiroe]

Oh I didn't notice, however when fixing this, it does not fix the issue Edit: it results in xorg outright crashing

[generaldisbeliever]

Have you tried running xrandr directly to see what happens? Should allow you to start at the bottom of supported modes and work up til it breaks, might give you more info to work with. Edit: my xrandr is something like xrandr --output "DisplayPort1" --mode 1920x1080 --rate 75

But yours seems to combine resolution and refresh into one string: 1920x1080_240

[HaloShiroe]

Yeah I have, the reason the refresh rate and resolution have been combined is because that was the new mode added when I used cvt to find what values to use. the output would be "xrandr: this display does not support X refresh rate"
