lag issue in office meeting

Hi, @alexsethi,

I'm assuming first that you normally have little to no lag for meetings on other topics.  Troubleshooting lag issues remotely is difficult, but let's go through a couple of things for you to look into which hopefully will help.

Are most of your workers working from home, or do you have a lot of them all on the same office?  I find many times a small or medium business with many employees onsite will have issues with lag. Don’t forget that every person in the meeting on your network is getting audio, camera video, and Screen Share video over your company's Internet connection.

Consider having most people turning off their camera feed, and see if this helps.

Also, make sure that anyone Screen Sharing does not have a 4K monitor – Screen Sharing video is distributed at full resolution!  If someone from outside or even inside the company is using a high-resolution display for screen sharing, that will push a LOT of data through your Internet connection -- way more than someone with a 1080 or 720 resolution screen.

Next time this happens, have someone open the Zoom Settings Statistics tab and look at the screen sharing items:

If the resolution is greater than 1280x720, or if they are sharing video at 30 frames per second (like this one), then you're getting a LOT more data through your router than normal screen shares,  and that can impact your lag and audio/video quality.  Packet loss rates above 0 mean there will likely be lag and broken audio/video issues.

See this Zoom Support article for more information on accessing and interpreting the Statistics available to you during a meeting or webinar:
