I am having an issue where xrandr refuses to output 3840x2160 at any frequency above 30 Hz. I have gone through the process of creating a new xrandr mode (arch wiki) and adding it to the mini displayport output that services my monitor, but when I issue the command:
xrandr --output DP2 --mode 3840x2160_60.00
I am greeted by this error message:
xrandr: Configure crtc 0 failed
This mini displayport is associated with CRTCs 0 - 2, however adding the --crtc 1 or --crtc 2 parameters only results in similar error messages.
The cables are all 18 Gbps capable and tested. I don't see how this issue would be with the hardware, as I know that on Windows the Intel HD 530 is capable of this output.
Does anyone have any bright ideas as to how this xrandr issue could be fixed?
