I've got quite a job here with so many factors against me in this temp install, but I'm SO close and am hoping there might be a miracle fix.
As the title says, I've got my BENQ W1070 rear shelf mounted, upside down, at the back of the room throwing onto an electric drop down screen.
I've got some height issues at the shelf mount point, so there are limits to where the projector can be, height-wise, as opposed to the screen (ceiling is lower at the mount point than the top of the screen). As such, I've had to tilt the front of the projector up ever so slightly higher than the rear.
Is that the reason I'm seeing a trapezoidal image, with the top slightly wider than the bottom? Is this a symptom of a projector that is tilted slightly upward?
Keystone seems to severe of an adjustment to fix this even though I think just a SLIGHT amount might right it.
If anyone wouldn't mind weighing in, after looking at the images, I'd sure appreciate it (the drawing is a bit severe but just to illustrate it in simplest terms).
I have plenty of tricks in the way of self-stick feet, coins, etc as far as raising any of the 4 corners up, though I have only around an inch more of height above the shelf I can go before the projector hits the ceiling.
