XPS 13 9350 4k Monitor Display Problems


I have an xps 13 9350 with the intel HD 520. I cannot get any output to my new external monitor. Its an Acer RT280k 4k monitor.

I am connecting it up using a Cable Matters USB-C to HDMI adapter (

At the moment I get the monitor sometimes indicating that HDMI is connected but no display and the laptop screen constantly flickering.

Should I be able to use this 4k display with this adapter over a HDMI cable? I have updated the drivers and the Dell System Update says its fully upto date.

Any help gratefully received.
