I don't consider 1.2 screen widths as that close, and the screen does not completely fill my vision periphery but as you can imagine it creates a very immersive picture. You want the image as large as possible - my idea of a home theatre is to emulate the large screen theatre experience. I originally designed the screen to have the maximum size possible and still be able to use my Dunlavy speakers (mains are over 6 feet tall) and not see screendoor. The intent was to use the room for 2 channel listening (it is full of acoustic insulation & traps) but I pretty much only watch blu-ray concert videos now as the audio on a good concert disk is discernably better than a CD.
I have the motors & electronics to automate the masking but need to find time to put it all together. I definitely recommend using horizontal masking for 2.35:1 on a 16:9 screen, it improves the apparent contrast of the image even though the HD750 is pretty good at keeping the black bars somewhat black, the masking makes the image float in a black void and enhances the picture.
Another benefit of a large screen is that the light at 0 IRE level is barely noticeable as the residual light from the projector is spread over the whole screen, effectively lowering the black level (however no increase in contrast as the max white level is also lowered). This advantage is somewhat offset by the fact that I can't use much of the iris as I need more brightness to light up the screen (on a new bulb the iris is 1/2 closed on max bulb to get acceptable brightness).
Now I'm just waiting to see what JVC has in store for their end of year new models as its time to trade up from my HD750 to a model with more brightness and hopefully 3D without ghosts...
