Hi and thanks,
I’ve never used a projector and am planning my first purchase. I’m also framing my basement and near to running conduit and electrical.
So if l
a) I use the pj’s zoom to fill 2.39:1 (at 120” diag), and
b) i use no zoom for 16:9 (94.4” diag), both using a 46.3” height screen,
c) For a projected image to fill a 2.39:1 screen with an image, I am projecting a big 16:9 image (127” diag), where the “black bars” are just above and below the screen.
I got this right?
If so, assuming i have a light controlled room covered in black velvet, how important is it for me to put the pj as close to the screen as possible?
(Assume I’m using a 1 gain screen and an Epson 5050 for now please).
If I can manage 16’ to the screen, I can put the PJ in a hush box going into a crawl space.
Last question: If I am getting this right, how critical is it for the lens of the PJ to be at the top of the screen in order to do CIH? I think it depends on lens shift and lens memory, but I-may be missing something. I understand, at least superficially, the lens must be below the top of the screen.
