Hello all,

Suddenly, my monitor connected to my Dell XPS 15 7590 laptop is displaying random moving pixels over images. These pixels seem to move and jump about as images are moved and zoomed in on. See an example here: View: https://imgur.com/9rNUVes


It only appears on my monitor connected to the laptop through a mini-HDMI. There is no display issue on the laptop itself. I'm not sure if this is related but this seems to have appeared after a recent Windows update to 19042.685. This could be coincidence though.

Things I've tried:

  • Switching out HDMI cables
  • Switching out monitors
  • Uninstalling Nvidia drivers and reinstalling (per the instructions on their website)
Specs are below:

Dell XPS 15 7590
i7-9750H
GeForce GTX 1650
32.0 GB RAM
Windows 10 (Up to date)

I have a warranty but figured I would check here first just in case.

Thanks in advance!
