Brand new to the forum. Sorry if this is an easy question, but I've been doing a lot of research and can't seem to find the answer. So my wife is letting me use the second bedroom in our new apartment as a home theater. I'd been looking at getting a big screen tv, but found projectors to be more cost effective, plus i don't go in for 3d and most tvs seem to come with that. The wall I'm putting the screen on is 9' high and and 9'5 wide. I'll be hanging the projector on the wall or ceiling depending on the model I get, which is 10'8 away. For the projector I'm leaning towards either the mitsubishi hc4000 or the epson 8350. My question is, will I be able to get a 100" diagonal image from that close? I checked out the projection calculator over at projector central, and it says the image will come out to 83" for the mitsubishi and 75" for the epson, but can you zoom the image so that it will fill up the screen, or will that distort the image too much? Thanks for any help.

The sizes you listed are the smallest sizes. After entering a 100" diagonal screen size for both projectors it shows this: 1) HC4000 - 100" diagonal needs a throw distance(lens to screen) of 10' 1 " or more 2) 8350 - 100" diagonal needs a throw distance of 9' 9" or more How did you come up with a 10' 8" throw distance? Did you measure from the screen to the lens(where it would be mounted?

Actually 10'8 is the distance between the walls, so it will probably be closer. I'd like to mount it as far back as possible.

WOW, that's going to be a pretty short throw distance. You need to deduct about 16" from rear wall because that's where the lens would wind up. So your throw will be about 9' 4". Using a 9.3' throw, the following resulted: 1) Epson 8350 - max. image size would be 98" diagonal 2) Mits. HC4000 - max. image size would be 94" diagonal 3) Benq W1070 - This is the one I would go with. Image size would be between 87" and 113" diagonal.

Those numbers are still pretty good. When you say the Benq is the one you would go with, is that because of the size or the image quality. I do like that it has lens shift like the epson.

Upon further checking, I'm unsure about the image offset of the Benq, so I'm holding off on that recommendation until I can verify it. A 100" diagonal screen is too large in my opinion. If your room is only 10' 8" deep, that means your seating distance is only about 9' to 9.5' correct? I would not go larger than 90" diagonal. How tall is your ceiling? This is important because the HC4000 has a large image offset. It is 33% of the image height. This means when ceiling mounted, the lens needs to be 15" above the top of image, for a 90" diagonal screen. If you want to put projector on a rear shelf, it needs to have lens shift, like the Epson 8350.

Projector central says you can get a 100" throw distance from 9 1/2 feet. The room is 9" high so that should be tall enough. Why no larger than 90"?

The size of your room and/or screen wall have nothing to do with the screen size you should use. Screen size is based on 1 thing: How far you sit from the screen. I asked you above if your seating distance would be about 9' to 9.5'. Is it?
