I've just installed a projector (Epson 5030UB) and am quite happy with the results so far... However, I've noticed when I use the full-lamp modes (dynamic, living room, etc.), which produce a lot more heat, I can see "waves" of hot air passing through the air in front of the lens. I think this is because of the way I've positioned the projector beside the wall (see attached image). The exhaust blows the air out toward the wall, then some of it likely bounces back in front of the lens to produce those "waves". This doesn't happen when I'm using the lower brightness modes (THX, cinema, etc.).
My question is, since my configuration won't allow me to move the projector, is there any way to somehow redirect the flow of the air from the exhaust, or even invert the flow of air through the projector (such that the exhaust becomes the intake, and vice versa)? I realize I could place the projector upside down on the shelf, but this would be far from ideal. I am hoping someone else may have encountered a similar issue and may have some suggestions. So far, I've considered placing a piece of cardboard to redirect the air upward, but I'm concerned about restricting the flow and shortening the life of the lamp. Will the projector display a warning if the lamp is too hot?
Thanks in advance for any advice!
