I bought an optoma hd 131xe and an Eliete Cinewhite 100" screen. Now my room is 10x10 and the projector us mounted on the wall. The screen isn't filled all the way. What can I do to fix this? Did I get the wrong size screen? Are there lenses that increase the screen size?

Please help

Thank you very much

I take it you zoomed all the way out? I'm no expert but the optoma is long throw isn't it. Which means I'm not sure if it will throw 100inch at less than 10 ft.

If your room is 10 feet, your throw distance has to be reduced because of the projector's lens distance from the back of the wall and whatever space is behind the screen. Using the Projector Central throw calculator http://www.projectorcentral.com/Optoma-HD131Xe-projection-calculator-pro.htm you needed 11 feet 10 inches for a 100" screen. Even the Benq W1070 would require 9'6" for that screen. You picked the wrong projector for your room size.

Well, measure from the front of your screen to the front of the lens where your current projector is mounted. If that distance is more than 9'6" you can utilize a Benq w1070 or Acer H6510. If not, you need a short throw projector. The only 1080p one on the market is the Benq W1080st.

42Plasmaman, that link doesn't show any of those Epson models capable of doing 100" at about 9 1/2 feet.

He only has a 10 foot room. At his close seating distance there's a limitation on how big you want to go unless he enjoys watching tv like a tennis match. And only a short throw will project larger screen sizes in that room.

well what i was saying is since he has the projector already, why not set it up as far back as possiable and see what the size is. My take on it, is that he wanted a 100" screen just to say yeah i have a 100" screen. We all know 100" for a 10" room i way over kill tennis match like you said. He has 2 choices, use the projector he has mounted as far back as he can an thats the biggest he can go or return the projetor for a different one...

When he said it was wall mounted (not ceiling mounted) I figured the thing was about as far back as it would go and based on the throw calculations for the 131x he's probably getting a 80 or 84 inch projection at best. Not really bad though. I think about 92" is good for a 10X10 room.

My bad. Forgot to account for the projector length.

One option is mount a mirror on the rear wall, face the projector to the rear and reflect the projector off it.
There's a specific type of mirror you want to get though so it's distortion free.
You could probably search for mirror or reflect in this forum since I've seen it posted many times as an option.

Here's one to get you started

Why not just go for a w1070, that will work on the throw dimension you have given.

I'm mounting a BenQ 1080ST today, a great projector in it's class.

Not sure which calculator you are using but the couple I use shows that from 9 ft you can get a maximum diagonal image of 112"

BenqW1070.jpg 115k .jpg file

According to the calculator at Projector Central, you can set up a screen that's between 83 and 100 inches at a 9ft throw distance. Therefore your 100 inch screen will work just fine with the BenQ W1070 if you mount it with the lens 9ft away from your screen.

Hope seeing the picture helps. Good Luck:cool:
