Well we can only try.....
The dimensions of the room are the 12.5' x 11' with 7.5' ceiling. Due to the rather small size of the room I can't go beyond 11' for the throw distance. There is one window, which will be covered with thick, dark curtains so as not allow any ambient light. The walls are light blue and the ceiling is white.
Ambient light is not so much your main issue as is "reflected light" from the PJ. That low a ceiling (89"), combined with a 110" screen (54" high)
leaves you with just 35" total wall remaining to set your screen onto.
So let's say you mount the Screen so that the actual edge of the Screen...whatever screen is chosen (I'll get onto that later....) is at 12" down from the Ceiling. That will only leave your 23" space above the Floor.
Why stay at least 12" from the Ceiling? Because that white ceiling is a giant reflector. Essentially, if you cannot...or will not consider a change in your room's color scheme, ANY PJ/Screen combo will suffer because of those light Blue Pastel walls and that Gawdawful White Ceiling.
Change 'em...or you must spend more elsewhere just to mitigate the issues they present. And...mitigate doesn't translate into "solve" unless you really
-my preferred size would be 110" (at least 106") and according to the projector-calculator, with a throw distance of 11' I'll have to use the zoom almost to the max (2.06x) to get the screen size I want. Is it OK to use such a high zoom or can it have some adverse affect on the picture quality?
You'll be OK. I've done likewise several times with the 8700 and it's very good at zooming at that size. It's the larger sizes (120" +)that tend to show aberrations when maximum zoom must be employed.
Also, the calculator give a brightness value of 42 fL, which seems rather high. Curiously, for Panny AE4000U the same dimensions give an acceptable brightness of 21 fL (even though both PJs are rated for same lumens). Does this mean that epson is "too bright" and if it is anything can be done to combat that?
It is to chuckle.....
You simply run the PJ on Economy, and calibrate it to resolve the maximum Black Level possible. Having extra brightness means you can always adjust downward. If you don't have enough lumens, you can't grow more. All you can do is go for a high gain screen...and that itself opens up additional caveats...such as extra cost, artifacts, reduced viewing cone, hot spotting. You want to avoid the need for such a screen unless conditions absolutely dictate such a need. So far...your's do not.
BTW, the 8700 is WAY brighter at it's stated luminosity level because it employs a Lens specifically designed to optimize the light passing through. The Panny's lens is not nearly as proficient, and there is a reason. It achieves it's higher contrast levels via attenuation. Yeah. It make the image darker so the Blacks get darker as well. Not good as far as I'm concerned.
-again, based on the brightness of the projector and white ceiling/light blue walls, what would be the best type of screen, gray or white? any suggestions for the screen manufacturer are welcome. (am leaning towards Elite screens).
Lean further and come visit the DIY Screen Forum.http://www.avsforum.com/avs-vb/forum...ysprune=&f=110
We got what you need at the size you need, and at 1/10th the cost. The image quality possible takes no back seat to Mfg., no matter what someone who sells Screens might say. Strong words, but well proven ones.
Your ideal Screen choice would be a mid-tone Gray with at least 1.2 gain. Easy stuff for a DIY'er to get'ter dun.
I'll bug you guys some more once I set up the PJ and have to calibrate
Better bug well before that, as I see you need considerable input to achieve results you can be "Suspender Poppin' Proud" of. Got to far too fast, and it's either a case of; "I guess I shoulda...." or worse, "I really wish I woulda..." The later is always a case where the sour grapes are particularly bitter tasting.
