What would be the safest angle you could tilt a video projector off level before the lamp blew, and I understand you can also operate them upside down then correct the inverted image in the set-up.
Commercial LCD &DLP projector mounts give a +20/-20 degree range.
I remember Kodak Carousel 35mm slide projectors didn't like too much tilt before you lost the lamp.
(I have been using mirrors to deflect the projected images into extreme low angle set-ups for a short experimental film.)

Look for ones that have keystone correction. Certainly, the lamp should be OK throughout the range that can be keystone corrected.

Vertical and horizontal lens shift works great if the projector has it.
