Blurry Slides & Video During Zoom Webinar

I ran a company-wide town hall today via Zoom Webinar for my organization.  During the call while I was sharing my screen, a few attendees told me that the slides were "blurring in and out." They described it as a camera lens coming in and out of focus. 

 

I have fiber internet with a mesh network and 5G router in my home office. I've run these calls with this exact same setup and network for months. This is the first time that I've encountered this issue. Has anyone else experienced something similar? How did you troubleshoot it to prevent it from happening again?

Were these all people working at your main office, or were some remote?

 

It sounds like network bandwidth/congestion issues, either way.  At home/remote, you're at the mercy of your internet provider, and if you're on a cellular connection, same issue.

 

Some people think that having everyone in the office attend via Zoom means no bandwidth issues... but keep in mind Zoom is then feeding one video stream to each of your participants.  All it really takes is one person Screen Sharing with a 4K monitor, and all of a sudden your bandwidth needs can quadruple... and some people are likely to experience issues.  (Screen sharing is sent to all participants in the native screen resolution!)

 

So not sure what your specific issue was, but there's some ideas to think about.
