I am using archlinux and Wayland with the open driver (proprietary also doesn’t work).
On Windows I can force 8 bit RGB at 165 Hz, but on KDE Wayland on the newest version of each software and 570 driver (hasn’t worked on any previous driver) I cannot force RGB. The driver forces the monitor into YCbCr, if I manually change the monitor to RGB the screen turns purple.
At 100Hz it is capable of RGB. What is interesting is there is no issue on Windows pushing this without editing the monitor settings at all or making a custom resolution it just works default.
Is this an issue with the NVIDIA driver or the display port driver on NVIDIA?
Does anyone know how to make this work.
