Zoom video freezes when connecting 14" MacBook Pro (M1 Pro CPU) to a TV with HDMI

I am the host of the Zoom meetings I am having trouble with.
I have brand new a 14" 2021 MacBook Pro with M1 Pro CPU. This computer works OK with Zoom using its own screen, but the Zoom video freezes when I connect it to a TV monitor using HDMI. The other Zoom participants have no difficulty with sound or vision. Audio works both ways for me.

Before purchasing this new computer, I have been successfully hosting Zoom meetings using a 13" M1 MacBook Air connected to the TV by HDMI.

Can you please help me with this problem.

Have exactly the same problem. Brand new MacBook Pro 16" with M1 processor. 2 external monitors connected through a Belkin docking station.

 

Zoom works OK if external monitors are detached so only the MacBook Pro screen exists. But if the monitors are attached, then starting a Zoom meeting freezes completely - have to use Force Quit or a Restart to get control back. Also tried Preferences -> Mission Control -> Displays have separate spaces setting both on and off - same result.

 

Have not had a problem with any other application using the external monitors.

Critical additional information:

  • If you try to start Zoom directly to start your own meeting, it freezes (shows Not Responding in the Force Quit screen).
  • If you click the link in an e-mail invite,
    • If your default browser is Safari, then it will freeze,
    • If your default browser is Chrome, then it works.
  • If you copy/paste the link in the e-mail invite, it works if pasted into Chrome, does not work in Safari.

Have to retract the above -- using Chrome failed once today and worked once. No idea what differences are involved.
