Best Practices for Hosting Large Meetings With Reliable Screen Sharing

Hi everyone 👋

I’ve recently started hosting larger Zoom meetings (50+ participants) regularly, and I’m running into intermittent screen-sharing problems when more than one person tries to share at once in scheduled sessions. Sometimes the screen stops updating or participants report lag, even though my internet is stable.

Before posting here I searched to see if others have asked about this already, but I didn’t find the exact scenario I’m experiencing. I want to make sure I’m following Zoom best practices and not missing a setting that could help.

Here’s what I’m doing so far:

  • Enabling “Host only” screen sharing for large webinars.

  • Making sure all participants have the latest Zoom version.

  • Using stable wired internet for my meetings.

My questions for the community are:

  1. Are there recommended settings in Zoom Meetings (for example, advanced sharing settings or bandwidth options) that improve reliability when many participants join?

  2. Does screen sharing work better under a specific layout (e.g., gallery vs. speaker view) for large sessions?

  3. Has anyone experienced improved performance by adjusting participant share privileges or Zoom account plan features?

Appreciate any tips especially settings that have worked for you or links to Zoom Community posts that cover this.

Thanks in advance! 🙌

    Screen sharing has numerous factors affecting performance. Lagging may not be the internet, but may be your CPU/GPU of the computer you are using. Since you did not share the specific hardware this is just a possibility. Screen sharing when optimized for video is off uses the screen resolution. So if you are using a 2K or 4K screen the shared image resolution will match the screen and may be challenging for the hardware. Screen sharing with optimize for video on will try to use the fastest frame rate possible usually at 1280x720 resolution and may prove to be less strain on the computer. Although multiple screen sharing is possible it usually requires significant computer power. Screen sharing with multiple participants can stress upstream bandwidth and computer power. Personally I have found that having a separate GPU card helps a lot. Monitor the computer usage to see how the activity is using the computer resources.

    hi ​@Hellencharless1 ,

    Screen sharing does consume power, based on the resolution of the screen being shared. 
    So if somebody has an 4k screen and shares it all of it, they are sharing 4 times somebody who shares a HD screen.
    The bottleneck for data is dependent on the upload speed of the person sharing, not just your connection.

    You are doing the right host things.
    If you audience is using standard HD screens then there is no reason to share a higher resolution screen.

    Does that help you?
