Why would you not want to use the entire LCD?
Maybe because you don't want to get another fresnell? Ok i think i got it.

Youde rather send a smaller image to the LCD to you can simply use the projector that you have.

Now for that i have no idea.

But the fresnells aren't all that much.

And with a few changes you wouldn't have that hard of a time.

yah, you got it...I pretty much have 3 options...

1) enlarge the fresnel(somehow-prolly mangle OHP) so at 15" stripped monitor fits completely

2) Use computer software to shrink the image on the stripped monitor(but then how do I play xbox n stuff on it?)

3) Just suck it up and lose the edges on the lcd...I don't mind for movies too much, but for games, it would make a huge difference...

well, just so you know, its not going to be all that hard to change things in the OHP. You simply need to make room for the new fresnell lens. Figure out what sife you need, and get a larger diameter one that matches the focal length.
