I have a Dell XPS 13 that I can output to a 1080P TV with no issues via USB-C to HDMI cable. However, I just bought a 4K TV, and am now trying to output my computer video to it, but it is not working.
It looks like Arch detects the TV correctly, screenshot below:
However, I do not see my desktop or anything outputted to the TV. I tried adjusting the refresh rates (24Hz and 30Hz) and it made no difference. Is there some additional tweaks / hacks I need to do to get 4K working properly?
Thanks in advance!
