2nd screen jittery image


Partway into a 2 hour zoom class, my 2nd screen (HP) shows jittery, grainy text for participants, chat and names of participants.  Dragging any of these to the 1st screen clears them up.  Other windows (PC Win 11) on the 2nd screen are just fine. This suggests the issue may be a Zoom issue and not a defective HP monitor.

Moving the speaker or gallery view window to the 1st screen (also HP) has it display normally.  Grainy, jittery again on the 2nd screen.


Has anyone else seen this?


I have a 2nd dual screen setup where this has not happened.  This suggests a DELL issue on one of my PCs. But if so, why does it only happen with Zoom?


All monitors are set the recommended resolution.

Hi @GreatBooksMike,

I am sorry I missed this! Have you tried completely uninstalling Zoom by running CleanZoom on your device: Download CleanZoom . Once completed, download Zoom from our download center and reinstall



Let me know if that helps!
