Any projection screen gurus in here?

A 16:9 wide 80" diagonal screen has a 39.2" x 69.7" area

A 2.35 wide 80" diagonal screen has a a 31.3" x 73.6" area.

Using those screens, the maximum exact size possible for these movie formats would be:

                     16:9 80"             2.35 80"

1.37 Academy      39.2" x 53.9"        31.3" x 43.0"
1.85 Widescreen   37.7" x 69.7"        31.3" x 57.9"
2.39 Scope        29.2" x 69.7"        30.8" x 73.6"

I'd go with the wider screen of course, then you'll see movies as they're intended to be projected. One of the pluses of having a projector

Your zoom ratio of 1.6 to 1 should cover that easily if you set the projector at a distance where the zoom goes between those 2 extremes (theorethically you could go from 1.33 to 2.75 BDs if you had a 2.75 screen too)

What's your viewing distance?

Your projector being a 720p one, I'd sit at about 8 feet. if everything was optimal.

Remember that in order to project the original 2.35 aspect ratio, you need an Anamorphic lens which I don't believe is an option on the model. Otherwise it will just be projected as 16:9 with the bars on top regardless of your screen size.

Correct. I would have to agree.
