I realize I probably should have just spent extra to get something full lens shift abilities, but I'm a sucker for a deal and trying to make this work.
I have a shelf mount BENQ W1070 I'm trying to get working. Want it to throw about a 125" diagonal image from around 14 feet back (distance from my electric screen to the lens). The problem is, I've got an 11 inch drop in the ceiling height where the shelf is due to ductwork. I've got the projector literally up right against the top of the drop, upside down (using rubber feet on the top and flipping it over), but it STILL is projecting an image way further down than I'd have liked.
I considered doing a tilt to have the front slightly angled up to project to the height I need, but it seems to be wrecking the geometry. I assume this is the case for any projector that you are trying to level-shelf mount and my own fault.
Before I hire an electrician to run an electrical outlet on the front of the drop so I can just shelf or ceiling mount it up there, any suggestions? The image here (Picasso-esque I realise) shows the current situation.
The yellow lines show what it's currently doing and the green line shows what I WANT it to do.
The top of the image right now, with the center of the projector lens sitting at 14" from the true ceiling proper (just 3 inches down from the top of the ductwork drop), yet the top of the image as it hits the screen is even more severe, at 19 inches from the ceiling proper. So it's actually angling downward (which may be because the 4 rubber feet I have on top are even and I need to make the back 2 shorter).
Thoughts? Or should I just have electrical run to the front of the drop, ceiling mount it there, and be done with this?
