Im not sure but I think there was a thread about the ps2 screen already. Try to do a search on it.

use a bit of common sense too (not to be mean). but, light has to pass through it right? so, if that is the case, you should remove everything in light's path, so it is see-through.

then, research where the fresnel goes.

Why use one of those screens?? They are low res 320*240 plus 100 something dollars. Where as you can get a normal projection panel for about that with 640*480 res and no mods needed. Most overhead projectors are meant to magnify 8 * 10 for the most part.

What I'm trying to say is this. Projection panels are larger and specially designed to be put on top of an overhead projector. Playstation screens are not as they are generally 5 inches. They are also lower resolution 320*240 (standard tv) which means it would be hard to get computer into them and looking good. Most panels start at 640*480 res (computer resolution). 5 inche screen would be good for a large slide projector.

So what you are saying is that if I could get my hands onto an LCD screen that does 1024 x 736 or higher then I could probably get a pretty good picture using a fresnal lens strategically placed in front of the screen and light it up a good 30,000 lumens?
