Sorry, this line was for the laptop screen. But i have realized the issue. A USB-C to HDMI 2.0 is needed, apparently the type-C multihub sold by Dell does not work for UHD. Changing to the USB-C to HDMI dongle has fixed the issue and 3840x2160 is available. I have a different question however: is it safe to work now with the lid closed or will the laptop overheat? I have switched off the screen for the laptop using xrandr.
