Resolution of zoom

[tympani]

So I have the basic paid account.  I am doing a zoom meeting to one single destination, but need to know what resolution I can send?  I see 720p is mentioned, but how can I send 1080p?  This is covering a single presentation from one room to another as a lecture.  Only one computer will be viewing with the feed then taken to the projector in that room.

Any info/guidance greatly appreciated
