poor quality when over 50 peoples in zoom


we have often zoom meeting /training on same network. When the zoom over 50 participant, the screen share and sound quality is drop. Sometimes, meeting/training is around 100 peoples, that become to be unacceptable.

We try to push half peoples to different internet link is no big different. Check the network utilization is not high. 

Any recommendation?

Hey @edmond, for your screen share issue, ensure you 'share computer audio' and 'optimize for video clip' when sharing content. Also, within your Zoom desktop client settings under 'Share screen' click on 'Advanced' and check or uncheck, "Use Hardware acceleration to optimize video sharing", and see if that changes or makes a difference for your Screen sharing experience. Along with Checking or Unchecking, 'Use TCP Connection for screen sharing'.


Just to note that in a meeting, the host’s connection quality can affect all participants during the meeting. Dependent on what occurs in a meeting such as a Video, Audio, Screen Share, Participants, Annotation, etc. Which all require bandwidth upload/download.
