Hi,
I would like to use QHD resolution (2560x1440) with my shiny new
computer and display. That resolution works if I boot Windows 10
(cough).
What do I need to do to use that resolution in Linux?
I first tried openSUSE 15.3 (kernel 5.3.18-59.19-default)
then I build a v5.14 kernel and tried that.
Both of them max out at FHD (1920x1080).
I am booting with "i915.force_probe=4c8a" on the kernel command line.
My desktop is XFCE4.

Dunno if I can 'help' get everything going - - - - but I do have some
ideas (having had to fight a lot to get my graphics sub-system working).
Start up a terminal as your user and run $ xrandr --verbose and then if
you would paste the lines up to the end of the EDID blob here. (Need
more info that what you provided. )
