Thanks Doug, I agree with you -- So am I also correct in assuming that if I move the screen itself where the left and right sides are equidistant from the back wall that I might be able to better remedy that issue in the lower right corner?
As far as the vertical lines, I also agree that looks like a height issue. So the basic idea here is for me to get the projector pointing as level as possible...If it's unavoidable to not have a little front upward tilt (I can only go so high before I hit the ceiling due to the drop at the mount point, the screen actually has 11 inches more of ceiling to work with), is this something I will just have to live with due to the necessity to tilt up? I am using rubber feet to cheat the projector up closer to the top of the ceiling and I do currently have slightly more in the front but I needed to do that to hit the top of the screen. I can continue adding a little more padding (I have about another inch I can go before I am out of room) but I think I'd need to add it equally or the top of my image would be too low. The screen can't go down any further and the projector can't go up any higher after that.
I do have the vertical lens shift of the W1070 maxxed out (it's very slight) which has helped but I will never be able to get the center of the lens above, or even even with, the top of the screen.
