Adding undetected resolution - xrandr: Configure crtc 1 failed

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.
