Try connecting via HDMI.
If you don't already have an HDMI cable, get a good one.
Should look for a cable that is sold as "high speed HDMI 2.0".

What make of display?
What model number?
What size?
What resolution (i.e., 4k)?

yea I did a bit more testing last night, the screen has a test cycle you can run it through (that is separate from any video signal its getting - you can even run it with nothing connected to it) and it still exhibited the flickering issues. Dell support was really great and already is shipping a replacement.

This is the Dell U3223QE (32" - 4k)
