If you didn’t follow the discussion thread on the story, we got some very interesting — and detailed — feedback regarding why hanging projectors vertically might be problematic (or not). Extremely narrow tolerances for heat and fragile bulbs are the culprit. The ultimate bottom line, though, is that the individual projector model and its internal configuration may matter more than anything. I just heard from a technician I’m working with at Casey Systems in New Jersey that at least one projector rep indicated it was no problem, again suggesting variations between equipment.

Of course, part of why I think people haven’t spent so much time on this is that using mirrors is usually more convenient than rigging a projector to hang on its side anyway. Even fully-automated motorized mirrors aren’t that expensive, and stationary mirrors cost next to nothing.

Got a myth you’d like us to bust (or prove)? Let us know!
