Of course, I am simply speaking from my own experience and not knocking any setup smaller than 110", but for me...anything less than 110" does not feel like you are truly immersed in the experience. So, the room I choose will have to accomodate this size.
...umr, you mentioned in an earlier post that simply choosing the right screen and projector are not the only factors. I am curious what else the factors would be? Lighting is obviously one...space probably another, but what else? If you have the space and minimal lighting, I am curious what else needs to be considered.
One question I have though- in movie theaters, you notice there are very low lit lights still on in the theater...it is not 100% dark. So, wouldn't it be natural then, in a home setting, to have some very minimal dim lighting as well? Just curious. The room I choose will probably have very little light...if there's a window, I plan to seal it off.
I find the impact of screen size once you are watching a film is totally a function of seat location. When you walk in a room the bigger the screen the cooler the room looks, but that is a different issue. The larger the screen the harder and more expensive it is to have a great image and sound. The further you sit from the speakers the more important room acoustics are to sound quality. The amplifier power requirements for sitting further from the screen increase dramatically and the speaker distortion will increase with it unless you go to more and more expensive gear. The biggest mistakes I see in home theaters are too big a screen, poor heat dissipation, poor room acoustics, poor speaker positioning and poor light management. For example one of the best home theaters I have worked on has a 15' wide 2.40 screen, but to make that work he uses a $40,000 projector and about a $200,000 sound system with very high grade self powered professional monitors. Trying to do big screens with cheap gear does not work very well. This is not to say 110" is a huge screen, but it is not a size that will be easy to light up and the room spacing for it will increase the cost of the audio equipment if you want to do it well.
Other factors to consider for video alone are relative screen size, throw ratio, projector location effect on fan noise level, wall and floor color effect on contrast ratio, screen height, seat location effect on screen artifacts, screen aspect ratio, anamorphic lens limitations, auto/manual zoom, lens shift capability, effect of screen gain on seating positions, target light output from screen when lamp is new and old, flexibility of projector iris/lamp output, acoustically transparent screen or not, effect of transparent screen on image relative to seat location, effect of acoustically transparent screen on light output, equipment light output effect on image, controlling projector light spill, projector location for optimum light output and contrast ratio, projector location effect on seating and possible head hazard, height of seating platform, HDMI cable limitations for projector relative to equipment location, how to condition power to the projector, how many cables to route to the projector, is a video processor required, impact of screen location on speaker positioning, and heat dissipation.
I find any light in the room detracts from the film. This is one of the advantages of a well done home theater. I find myself drawn to any lights in my field of view. Lights will also reduce the on/off contrast and potentially alter the color of scenes.
