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?


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. )
