Zoom app screen share drops video quality drastically after a few minutes

Hi everyone,

I’ve run into a frustrating issue with the Zoom desktop app (latest version) on both Windows 10 and macOS Monterey. During meetings, when someone starts screen sharing, the shared content begins fine, but after about 3–5 minutes, the video quality suddenly drops, it becomes blurry or pixelated even though the original content was clear.

Audio stays okay, bandwidth is good (tested 100 Mbps up/down), and this happens whether we’re sharing a PowerPoint, a browser window, or a video. We’ve tried:

Updating Zoom to the latest build

Turning off “Optimize for video clip”

Disabling HD in video settings

Testing with hardware acceleration on/off

None of these seem to fix it, and it doesn’t happen immediately.

Hi @Hous, I can assist you here. Can you help answer these questions for me:

  • Do you have meeting ids of topic names of meetings where you experienced this issue?
  • Is it only your device where the issue occurs?
  • Just to confirm, you’re using the Desktop App available here zoom.us/downloads or the SDK?
