Basically, a CIH setup uses a 2.35:1 "Cinemascope" screen (as opposed to the ubiquitous 16:9) and presents narrower formats (1.78, 1.85, 1.33) within it...with masking only on the sides.

I'm using an InFocus 4805 projector and a Panamorph 752 anamorphic lens. The 4805 does all the scaling, and the lens stays in place…I set the projector to "Letterbox" for 2.35-2.4:1 and "4:3" for 16:9/1.85:1. The screen is a quick one I put together using heavy-duty artist stretcher bars (more expensive but much truer/straighter than anything at Home Depot). 70" width (bars from from my old 16:9 screen) and 30" height, about 76" diagonal. (Yes, technically a 2.33:1 screen…but the bars don't come in 1/4" increments. ) $10 worth of blackout cloth covers them. I view from 10', so the 1.7(width) distance is about where I want to be with the 480p projector. Certainly stunning for the price, and the fact that the 4805 can do all the scaling I need is really cool.
Scope image is certainly improved due to the use of all available pixels, and I really like the presentation.
