And in case anybody has any doubts, I left out the word CRT
in my post above, when talking about ceiling projectors. But all comments made in my last post refer to CRT (usually front) ceiling projectors,
the triple gun kind. In case anybody has any doubts...
Mustang, the front-firing ceiling pjs were many times as expensive as our CRT RPTVs and had advanced electronics that ours just didn't have. So yes they will look better than our RPTV versions. I have a Barco Data 800 ceiling pj in my garage that I have used on my sun room wall, and with an even bigger picture than my 73" Mit, it is still crisper and with more depth than the Mit. And that's with 8" guns vs. my Mit's 9" guns.
Leo, if you do a rear projecting scenario using a front projector, you can get away with a lot more room lighting before starting to compromise those fine, inky blacks. A reflecting screen will compromise those blacks by reflecting back in the blacks whatever is going on in the room as far as ambient lighting goes. In a rear projecting scenario where everything behind the translucent screen - or in best case scenario, the same kind of fresnel/lenticular sandwich screens our CRT RPTVs use - absorbs
that ambient light and keeps the blacks much much darker than a front projection scenario does, when factoring in the picture-compromising effects of ambient room lighting. When of course the intrepid calibrator or installer who set the whole thing up makes sure everything behind that screen is either blackened or black already!
Which is one reason our CRT RPTVs do so much better in the daytime than front projection does. It would be very effective even with a translucent screen, but since ours are the fresnel/lenticular kind - the best - our projected light levels get gathered and aimed and basically turbo-torch beamed
at us, whenever we are sitting within the horizontal sweet spot of a horizontal line drawn across the room straight out from the screen. Alert owners/viewers even make sure their screens are pointed slightly down if necessary, to accommodate couches that make eye levels lower than the actual horizontal line firing straight out from the screen's center.
I know in your viewing room this is unnecessary, but in mine I use a 2x4 under the rear of my Mit to tilt it down just enough to have the sweet spot hitting my eyes whenever I am sitting on that couch, rendering my eyes the highest light levels possible in the current setup.
