I've noticed a fairly consistent and worsening flickering with my new Dell U2720Q where the display goes dark and then reconnects.

At first I thought it might have been a loose cable but I've ensured that the USB Type-C cable is tight at both the monitor and laptop end.

Any advice on troubleshooting or isolating the problem?
