Increase video quality for screen sharing.

Thanks for the feedback. You are right that the current limit is 1080p resolution as per Microsoft documentation.

There has been calls for this online for a long time about going beyond 1080p - for example, to 4k. Microsoft restricted it for a while to 720p because of platform scaling, but I think we are at the point it needs to happen, especially as cameras like the Brio support it. 

I have raised a feedback for you here. I am sure there was one previously on Uservoice but this doesn't seem to have been moved over. I would recommend voting up and getting as many to do so to get it in front of the product team

Hope that answers your question
