I'll throw in some additional thoughts. I've done a lot of screenings in
spaces about the size of what you're discussing, around 1000-2000 square
feet, with a projection surface of up to 120 inches diagonal. A few
DLP vs LCD:
Like you I much prefer LCD, I hate the rainbow effect. Screen door effect and
poor contrast are pretty much a thing of the past with the latest
cinema-oriented LCD projectors. My personal preference is for Panasonic
brand projectors, they have a very nice look, very fluid, but they do
sometimes have some quality control problems with discoloration at the top
and bottom of their LCDs.
16x9 vs 4x3:
I often project 4x3 format material on a 16x9 projector and it looks fine.
Frankly, almost all high-contrast projectors are 16x9, so you'll likely get
the best results from the point of view of picture quality from a 16x9
projector. The 4x3 projectors tend to be more designed for office
presentations and tend to be bright but have poor contrast and color
My Panasonic is a "short throw" projector which may not be ideal for your
needs. You can see throw range and screen size for most projectors on this
site: http://www.projectorcentral.com/ which is also an excellent resource
for projector reviews.
As long as you have no ambient light the fact that the room does not have
black walls shouldn't be a big problem.
