Monitor not working

Hello! I have recently gotten a samsung odyssey g3 and it has been having some weird problems, it doesn't get recognized by the system at all, even though the bios and grub show up on it. My laptop running void linux has no problem connecting to it and if I start my system with my tv plugged into the the hdmi port, get x running, change settings in xrandr and then change the hdmi port to my monitor it works. I don't have a DP cable to try that connection but as soon as I get one I'll try it

here is my /etc/X11/xorg.conf.d/20-amdgpu.conf

Section "OutputClass"
     Identifier "AMD"
     MatchDriver "amdgpu"
     Driver "amdgpu"
     Option "VariableRefresh" "true"
EndSection

I don't know of any other config files that would be related to the problem

?

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General and the output of "xrandr -q" before, during and after your mitigation steps (and record what "things" you "change in xrandr")

Re: Monitor not working

Hello! I was sleeping when you responded but using the display port worked just fine. What I think happened is that Linux read the monitor's EDID and tried to set the refresh rate to 144hz and my hdmi cable couldn't handle it, which would explain the laptop working because that set to 60hz by default while now it automatically was set to 144hz
