Q & A: Projector Mounting

I have a special effect application that may require a 2K lumen DLP projector to be mounted on its side (3:4 aspect ratio). Are there any compelling reasons against this?

A. This is no different than mounting an LCD panel in portrait mode. Two issues come to mind: The mount may need to be modified, and an auxiliary fan may be needed to allow for natural air flow. Being mounted on its side, the hot air from the lamp housing returns to the projector via convection and, of course, hot air rises. Putting an auxiliary fan at the rear of the projector will help move the hot air away from it, keeping the housing at normal operating temperature.

Next Month's Question

I've got a large church sanctuary that is 80 feet from the altar to the back wall, which is hard, untreated Sheetrock and curved. There is an audible slap-back echo from sounds produced at the altar area. What's the best way to determine where those reflections are coming from, and how should we treat the offending surfaces?
