I am building a home theater from scratch. I want to know sitting between 8' and 18' whould a 15 foot diagonal sizes projection be too big? Would the grain/pixals be too anoying to enjoy the show. Using a JVC DLA-RS2 with a 20 foot throw.

8' is to close. For way more reasons than just being able to see pixel structure.


I have to ask here.. How big is your room? Your going 16:9 on the screen or 2.35?

I think for comfort and field of view you shouldn't go much if any bigger than 10' on the screen. Maybe stretch it to 12'.

Your asking to much of the projector anyways unless you get a maximum gain screen as well which creats mounting issues to actuall achieve the gain, ect..ect...ect...

The room is 20 wide by 24 long. The projector will be mounted near the top of the 9 foot ceiling. The throw approx 22 feet. Seating starting at approx 8 to 10 feet from the screen, with principal seating behind that at 18 to 20 feet from screen. I would love to have the screen 15 or 16 feet diagonal in size.

The numbers are not working out here.

You will need as much gain as possibe, to acheive the gain your going to have to have to projector mounted center of the screen more or less.

You need more brightness than an RS2 can provide here.
