4K@30 video output does not work properly on Pinebook Pro
#1
Bug 
Hi,


I have Pinebook Pro connected to LG 27UD88-W monitor via USB-C to DisplayPort cable. I'm running Manjaro ARM 21.06 (Linux kernel 5.12) with Sway WM. The problem is that I can't run 4K @ 30Hz properly (right 1/3 of the screen is distorted). FullHD (1920 x 1080) and WQHD (2560 x 1440) works just fine. I have also tested X11 based Linux distros and the issue is the same. Anybody had luck to run 4K @ 30Hz video output on the external monitor?





This is the similiar thread, but it is closed.




I will be more than happy to provide more details if necessary.





Code:
$ dmesg | grep cdn-dp
