Semi-Constant-Height w/ Electric Pulldown Screen

post #1 of 2
Thread Starter 
I just moved into a new house w/ a 3rd floor bonus-room that is now a dedicated home theater. My video equipment is as follows:

Panasonic AE700u Projector
Ultra 100" 16:9 Matte White Electric Remote Pulldown Screen
Toshiba HD-A1 HD-DVD Player
Motorola 6412 HDTV DVR

The room is 15 x 25 but with a 15 x 12 section blocked off for the HT. At both the front and back there is a pitched section of the ceiling. To get the desired screen size (100") AND keep the screen above the top of my equipment shelf both the screen and projector had to be mounted on the pitched area of the ceiling. The screen is about 16" off the wall. I've attached a MSPaint diagram of the room setup (teal = projector, gold = screen, black = speakers, brown = chairs, blue = equipment stand, orange = end-tables, dashed-line = pitched-ceiling)

The other night I was rasing the screen at the end of a 2.35:1 movie and noticed that the image on the wall fit perfectly between the bottom of the pitched part of the ceiling and the top of my equipment rack. This lead me to the idea that I could paint the wall behind the 100" 16:9 electric pulldown screen in 2.35:1 and have what I'm measuring at around a 106" diagonal 2.35:1 screen. Then I could have the electric screen down for 1.78:1 and 1.85:1 aspect ratio material and raise it to reveal the 2.35:1 screen for 2.35:1 and 2.4:1 ratio material. I've attached a diagram of how I see the screens in place.

Has anyone seen or done a similar setup? I know it's not a true constant-height setup but in my situation (where everything seems to just fit right) it seems to be an easier and slightly more elegant solution. It doesn't require any new equipment (scalers, anamorphic lenses, curtains, masks) and also won't require any adjustment of zoom on the projector for different material. The only down-side I can currently see is that I would see a bit of the 2.35:1 back screen sticking out of the sides of the 16:9 front screen when it's down. This seems like a minor problem that would rarely be noticed, especially w/ the room darkened.

Any input/comments/ideas?
