1 - As I understand it, unless you can swing an anamorphic lens, if you do CIH you're going to waste pixels getting the image to fit properly on a scope screen (correct me if I'm wrong). So... why aren't there any projectors that natively project in scope Vs. 16" x 9"? Seems like a wasted opportunity for projector manufacturers.
2 - For scope, I've seen 2.35 and 2.40:1... which one is better for CIH? Flip a coin, or are there reasons to choose one over the other?
3 - If you get a faux-k projector like the Epson 5050UB, do you need a 4k screen or would that be a waste (other than future proofing)? Could you get by with a "4k ready" screen?
