I have a Samsung KS8000 TV which I’ve been attempting to connect to a ZenBook S UX391. It connects, however, it is unable to identify the display, and the resolution is limited to 1024x768 (for both mirror and extend). I have installed
intel-vulkan and it is connected via a HDMI cable to a USB C dock which I have confirmed works fine. Xrandr output:

The TV should support up to 4K resolutions, so what more can I do?
