Screen Sharing Lag

[JamesBnSD]

I have been using zoom for a few years on an older computer and needed to upgrade my desktop.  I purchased a much better computer, reinstalled zoom, same camera/monitor/speaker, same wifi.  Now every time I join a zoom meeting and go to share my screen it lags REALLY bad. Like a minute plus. I have also seen an alert saying my internet connection is slow. HOWEVER I have a great wifi signal.  I also can see other screen sharing just fine. I also can use google meet and share my screen just fine. I uninstalled and re-installed zoom, checked every setting, searched the net. Still can't fix and it is greatly affecting my work. Please help!
