I recently acquired a home theater completely built out. The projector setup as I inherited it had left some white space on bottom of the screen which I figured I could fix. I have monkeyed around with changing the projector's zoom to try and fill the screen - the problem I am having is that if I zoom in enough to fill the screen vertically, the width of screen goes well into the masking on sides of screen and that is a visible spill-over. If I zoom less, I am left not filling the screen vertically completely. The projector and lens have ceiling mounts already installed so moving the location of them on ceiling would be very problematic.
Is this normal at all and to be expected, or is this something I should be able to fix myself?
Screen: SMX 130" wide x 54" height, 2.40:1 curved Audio-transparent.
Projector: InFocus IN83
Lens: Panamorph UH440
