I have just mounted a SONY VPL-BW5 to my ceiling in the basement. I am in a rush right now, so I haven't been able to get a picture, but I will do my best to explain the image. The projector is around 12' away from the way, and is projecting a 100" diagonal image on the screen. My problem is that while the top of the projected image is even with the ceiling, the bottom is not even with the floor. After examining it, it seems that the height of the left side of my projected image is around 1 inch longer than the right side, leading to a non-rectangular shape. I can't exactly visualize what adjustment would be needed to correct this. Anyone have any ideas?

The projector is not square to the screen so the side that is shorter is closer to the screen. You need to make sure that the projector is mounted properly. So that means that you will have to rotate the projector until you have a square image. And then you will have to shift the projector over to get the image on the screen.


We say this so many times here, a good image starts with a proper installation. The screen has to be exactly perpendicular to the the throw of the projector and the lens should be on the vertical centerline of the screen. And the projector should be mounted vertically according to the manufacturers guidelines, which with most projectors, means it will be near the top of the screen.


With projectors that have lens shift, this is not as critical. Your projector does not have this feature.
