Improve quality of a Teams screen-shared video?

erimo This issue was resolved.  However, in order to resolve it, we needed to  know how networking works in Teams.  Here's a great video.  https://youtu.be/vi3M7ZzF2NU  It's about an hour long, but well worth it.

We put together a few test cases to verify the components of the system we control, specifically, the end points.  We did a direct call between computers on the same LAN and attempted to stream the video.  Fail.  Since this case did not require any communication to the Microsoft Cloud (see the video), we were able to identify that the source computer just didn't have enough horsepower.  After switching to a more powerful computer, we could stream video up to 720p without any performance issues.  We brought the Microsoft Cloud into the loop by changing from a direct call to a meeting.  There was virtually no difference in performance.

In further testing, we found anything less than an i5 would struggle.  But as long as you have a decent machine and work within Microsoft's network guidelines, everything seems to run pretty well.

At least that is our experience...
