Mac User's System Freezes when Sharing Screen


I have a Mac user that has recently started to experience a system slowdown to the point of freezing when sharing their screen in Zoom.  The user said that it only happens when sharing their screen in Zoom & that the rest of the time their system performs just fine.  We've already tried a general uninstall/reinstall of Zoom and checking for updates with the reinstall, and the user's tried unchecking the advanced share screen setting: "User hardware acceleration to optimize video sharing". 


I've read in forum posts that potentially checking the advanced share screen setting "Use TCP connection for screen sharing" is helpful, but I'm not sure what, if any, downsides that could cause. 


We've also reset the user's NVRAM.  


Does anyone have any other ideas that we could try to speed up the user's experience of Zoom while sharing their screen?  I'm including the system specs below.


System info:

MacBook Pro (15-inch, 2018)

Processor Speed: 2.30 GHz

Processor Type: 8-Core Intel Core i9

RAM: 32.0 GB

OS: Monterey 12.6.1





Restart Your Device
A restart often resolves most computer problems, including screen sharing issues. If using a Mac, go to the Apple menu and choose Restart. And if you are using a PC, open the Start menu, select the power option and click Restart.

Hi Rachel,

Part of resetting the NVRAM is to restart the computer.  So no restarting the computer did not help.
