I had been using a fixed-mount goo screen for a few years, but recently moved and had to start using a cheap pull-down Da-Lite (OK, the goo screen was even cheaper ).
I don't know what gain the Da-Lite is...I think it's matt white, but maybe not.
Here's the problem:
I have the projector mounted to the ceiling (just like I used to have), so the lens is basically even with the top of the screen, or somewhat above it...it's not in the perfect location height-wise, but it's close.
What's happening is that if I stand up, I see a much brighter picture than if I am sitting down...it looks like more light is being reflected back UP, toward the projector, than there is DOWN, toward where people are sitting...strange, because if the light was free to do what it would naturally like to do, like a flashlight onto a mirror, the light would reflect DOWN toward the audience.
Anyway, I'm wondering what the solution to this is:
1) Getting a new screen that does not have this strange behavior (perhaps my screen is more than a 1.0 gain and there is something sbout that that makes it reflect light back UP toward the projector?...my screen was probably meant for meetings and such where the projector is down on a table?).
2) Putting the projector down low, like on a coffee table...but I'd rather not do that as logistically that's a mess for me.
Would a different screen of some kind reflect light DOWN toward the eyes of the audience?
Thanks...
