If I was setting up the Vision to watch a 1.66 AR film on a 16:9 screen, what would the configuration settings be? I.e., AFAIK
most (all?) 1.66 AR films aren't anamorphic, so if you use the LTRBOX setting (which is basically what it is), you'll lose image off the top and bottom (since the LTRBOX setting scales up what it assumes to be 1.78 material).
OTOH, if you use the 4:3 setting, you'll have sidebars AND black bars on the top and bottom. I guess that means you'd just use the standard 16:9 setting, which would display full width, with some letterboxing bars above and below.
I think I just answered my own question, so how about this one?
If you were displaying a 2.35 AR anamorphic film, what would the difference be between the normal method of saying you had a 16:9 screen (1.78 output AR), at 720p; versus lying and saying you had a 2.35 AR screen, at 540p?
The same number of scan lines would be used for the active image in each case, but the later would use only 75% of the bandwidth to the PJ, and would also allow the Vision to generate 33% more samples on each horizontal scan line. Sounds like a win-win situation, with the proviso that you'd need to set up and align another memory on your PJ.
Would you need to adjust any of the settings on the input side?
