Hi, I've trouble getting 3840x2160 resolution to work. When I try to switch to that resolution the monitor says resolution is 3848x2160 and display is all garbled. 2560x1440 works fine.
Also, If I try to login to Gnome (Wayland) I get blank screen and I'm back at the login screen. X11 lets me login to the system.

I've fetched the latest updates (apt update && apt upgrade) and I've just ran firmware update using armbian-config.
Edit: display is connected via usb-c - - > displayport cable.
