But, I just read about the Stewart Reflections 170 , which has a gain of 1.7, dropping off somewhat off-axis. Since we sit 15 feet away, the gain should be fine for most viewers. I have excellent light control. What do you guys think about that combo?
If your screen is truly 1.1 gain, then to get 14ftL in 2D, you need 715 calibrated lumens. That sounds quite feasible with the 150 if it loses the usual amount of light to calibration.
With the 1.7 gain screen, is it available perf'd and if so what's the gain? If we assume 1.6 actual gain, and if we assume that the 150 yields 800 calibrated lumens, that's 22.75ftL for 2D -- you might be turning it down quite a bit unless you like a really bright image. (I find 14ftL great for movies.) If we assume the same light output for 3D and it loses 70% to the glasses, you'd be just shy of 7ftL, which is better than a movie theater.
Others have said that the low blanking on the Sim2 glasses yields better brightness than other machines, and maybe you could run in a "dynamic" mode for more lumens, too, so you might be able to gain a bit more brightness still.
So, to me it seems like you could get great 2D with your existing screen, and probably very good 3D with the 1.7 screen.
Also note that with the numbers above, you'd hit about 4.7ftL on your existing screen for 3D, which is comparable to a commercial theater. If 3D isn't a big deal for you, that might be good enough at least to start.
