Yes, the projector is 1080p. I've worked through that mess by carefully forcing video resolutions and I can still have an issue with the Mac's while the projector is not in use.
I don't know if anyone is attempting to use 3rd party dongles.
How are you "forcing" the resolution of a mac that someone brings without any sort of EDID management?
