At 10' away, a 120" screen will occupy 47° of your horizontal view. If you are 8' away from a 2' false wall, then a 96" screen will occupy the exact same 47° horizontal viewing angle. The image size hasn't changed.
Why not? Are you after a large, involving image or is your goal to have a physically imposing object (screen) in the room?
My point was you're sitting 8.5 away from a 60" screen. Sit in your 8.5' viewing distance and try to picture a 120" screen. Sit at 10' and picture a 120" screen. Every little bit of distance helps. If was going much smaller on the screen I'd get a TV, not a projector.
And, you're right- the screen to seating distance is not anywhere near 'recommendations' but I like the large screen. I always sit closer in the movie theater.
In reading this and other forums I see a lot of people with both huge screens and thousands, if not tens of thousands, of audio gear laid out with little respect to some of the info you've given me and I've read in other places.
In the movie theater, the audio is setup to give a majority of the viewers a good sound regardless of the seat. However, the screen is where it is. The viewer gets to choose the 'view' they like the most (if they get there early)
I'm convinced enough to spend my time and energy getting the audio as close to 'recommendations' as possible, that makes perfect sense to me. I'm also convinced that going larger on the screen is much more of a personal preference and that going outside of 'recommendations' will have very little affect compared to doing the same with audio.
I hope that makes sense. I'm not the best at putting my thoughts on paper, but I try.
