I want to use a high gain screen for 3D only to make up some of the light losses. I know mounting the PJ high is not ideal but what will I loose by keeping the PJ at the height of the top of the screen and say using a HP 2.4 or 2.8.
I already have a 2.35:1, 120" diagonal Screen Innovations solar 4K which is actually measured to be 1.37 gain. 2D is fine, 3 D a little dim for me and that is running 3D on a a 16:9 @ 95" diagonal .
I just figured if I bought a second screen to drop for 3D only maybe I would gain back some of the light lost using the glasses. If I have to drop the PJ too that will be a bit of an issue.
