I have just installed popOS alongside windows 10 on my machine, and for the life of me, I can't figure out how to get my ASUS ROG PG278Q monitor to display its full 2560x1440 resolution at 144Hz refresh rate. I've tried using xrandr in the following way and I get "out of range":
xrandr --newmode "myMode" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
xrandr --addmode DisplayPort-0 myMode
xrandr --output DisplayPort-0 --mode myMode
I even tried setting the resolution to 1920x1080 and this STILL showed up as "out of range". I have a dual monitor setup (both are 2560x1440) and my alternate monitor works just fine. It displays the correct resolution and is running at the correct refresh rate. I just can't get the PG278Q monitor (my primary one) to work.
I am currently using the open source "amdgpu" driver on my AMD Radeon RX 5600XT. Not sure if this would be the issue or not. Does anybody have any suggestions on how I can get my monitor to display its full resolution?
In windows 10, both monitors work fine and run at their marketed resolutions and refresh rates, so I know it isn't a monitor issue.
Thank you in advance!
