Hi guys,
I'm running into a problem with adding an undetected monitor resolution.
I'm running the commands as described on the wiki https://wiki.archlinux.org/index.php/xr … esolutions
cvt 2560 1440 # Get the modeline
xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493
-hsync +vsync
xrandr --addmode DP1 2560x1440_60.00
xrandr --output DP1 --mode 2560x1440_60.00
But after the last command I simply get:
xrandr: Configure crtc 1 failed
I have found one other thread which seems somewhat related to what I'm running into here https://bbs.archlinux.org/viewtopic.php?id=185937
But I can't really seem to figure out how they decide whether it is the EDID that is wrong.
My screen: Samsung S27D850T
My laptop: Dell XPS 13 (9350)
Any help would be hugely appreciated as I'm completely stuck on what to do next.

Hello. Did you ever manage to solve this?
