4k Monitor resolution not detected (xrandr: Configure crtc 0 failed)

wuegsd · 5 December 2021 18:38

My 4k monitor resolution is not being detected. The Highest I can get in the display settings is 2048x1152. I tried to add the higher resolution with the following commands

cvt 3840 2160

xrandr --newmode "3840x2160_60.00"  712.75  3840 4160 4576 5312  2160 2163 2168 2237 -hsync +vsync

xrandr --addmode DisplayPort-0 "3840x2160_60.00"

xrandr --output DisplayPort-0 --mode "3840x2160_60.00"

However when I run the last command I get an error message stating

xrandr: Configure crtc 0 failed

your version kernel is EOL
you need to add

sudo mhwd-kernel i linux510
sudo mhwd-kernel i linux515

press Esc on Reboot and select another version kernel you will remove after old version 5.13

@stephane Thank you for the tip. I did update my kernel and restarted my system. I am now running 5.15.2 but I am still getting the same error notice. Any other ideas would be greatly appreciated.

I am having a similar problem as @wuegsd

Video Card: AMD rx590
Monitor: Gigabyte M32U
Kernel: 5.15.12-1-MANJARO

I did a little digging into Xorg.0.log (see below) and noticed that Xorg managed to detect all the potential modelines correctly when it is probed. However,. later on, DDC is invoked and the modelines don’t reflect what is probed earlier in the log.

Unfortunately, amdgpu doesn’t make available the options NoDDC or DDC to disable it.
