Hello,
I woke up this morning and I noticed that my display no longer supports 144hz with hdmi 2.1 in xorg I only get up to 60hz. I tried wayland just to see what it would do and I only get up to 120hz. I switched out my cables to displayport and again I only get up to 120hz in xorg.
Here is my xrandr -q
