In another thread Zombie10k recommended an Epson 5030 for the theater I am helping my Dad design.

So based on his recommendation, I am trying to setup a 120" (likely HP) screen to get the best 2D/3D combo we can. The problem I am running into is that the online Epson calculator must have some sort of error in it because it doesn't seem to match with the owner's manual.

Best I can tell from their bad instructions is that in ceiling mode the bottom of the image is going to be ~88" from the lens center. For my dad's setup, we want the screen bottom to be at about 24" off the floor (10' ceilings), so that would put the projector hanging about 8" down.

If that's true I have two options. Inverted shelf mount on the back wall (about 21' away from the screen) or ceiling mounted anywhere along the path up to the nearly 12' minimum distance, but I don't think either of these is what Zombie meant when he said to center the projector to the screen.

Any thoughts would be much appreciated.

Forget the Epson calculator, it has issues. The 5030 is a very easy projector to install since it has extensive lens shift in the vertical and horizontal. With a 10 foot ceiling I see zero issues. Just make sure to center the projector to the screen width.

Personally I wouldn't mount a projector that far (21 feet) from the screen. Rule of thumb - not too close and not too far, 16 feet is about the sweet spot unless this distance interferes with your setup.

Not sure about the selection of an HP (High Power) screen, there are disadvantages.

With a HP screen, you want the PJ centered as much as possible vertically as well as horizontally. The image brightness is substantially reduced when viewing off axis.

Thanks, 16' is doable and we should be able to mount it without using much, if any, lens shift.

I guess I need to read more because this is what I am kind of missing -- Does "centered vertically" mean that it is mounted right where it should be so that there is minimal vertical correction or does it mean you should have the pj rightside up so that it is physically lower on the screen.

It means for a HP screen to look its brightest, the PJ lens should be as close as possible to eye level - the higher the gain, the more directional is the light reflected. Move the PJ up or down, you'll lose gain - just like if you stand up from your seating position, the image will dim. Think of some of the old rear-projection TVs, where you had a very narrow viewing cone with a reasonably bright image.
