*2.35 correct
*1.33 Yes, I don't watch much 4:3 material on my projector, but if I did, your right, the height would be the same, and if I masked the sides, it would require to mask the side bars, and the excess screen.
*1.78 Yes this is true for HD material and a few dvd's that believe it or not, are in 1.78.
1.85 I'll have to test this some more when I get a chance. I know Theatertek also has Overscan custom settings, so I assume it would treat it just like a standard DVD player. It has what is called a "Smart" mode which automatically adjusts to various ratios.
hmmmm you have me curious now.
