Is there a DLP projector that has similar offset specifications to the InFocus X1? The current set up is X1 projector 10" below the ceiling. Ceiling height is 7' 8" Screen is 16:9, 96" diagonal, throw is 16' The center of the lens is 0.2" offset from the top of the image. The projector is currently behind the seating area and, needs to remain there.

Checkout Optoma HD33. If you use V Image shift you can achieve this. I'm planning to do something similar - except the projector will be on a shelf slightly lower than the bottom of the image.


Edit : Scratch that. 5% vertical shift is just 1 or 2 inches. You probably need some 7 to 10 inches.


Only 1080p DLP's that have vertical lense shift are the old projectors like Benq W2000 from $2K. Rest are in the more expensive category. Checkout ProjectorCentral.

Your numbers aren't adding up. The X1's vertical offset in 16:9 mode is 32.9%. For a 96" diagonal 16:9, that's ~47" screen height. (.329 * 47) says your lens center is offset from the image by 15.46", not .2" as stated. Throw distance is irrelevant for the offset calculation.


To find a suitable replacement, just find something with a similar offset in the specs. I believe the Mitsu DLP's are usually in the 3x% range, IIRC.


Just to complicate matters. If you're looking for matching vertical offsets to reuse an existing mount location, you'll also need to match the X1's horizontal lens offset since the X1's lens is not centered with the chassis mounting holes.
