QHD(2560x1440) @ 240hz not supported/working
xrandr -s 2560x1440 -r 240 shows Failed to change the screen configuration!
on FullHD it works(at 240hz) on Linux
Also on Windows it works(at QHD @ 240hz).
GPU: AMD Vega 64 Monitor: HP OMEN X 27 QHD
Sorry if this isn't the right place for the issue, not really sure if thats a kernel thing / firmware thing or anything else
