There is lots of talk about the vertical lens shift on this model. From what I have read it also has a horizontal lens shift. How much could I shift the lens to the side? Could I put the projector say, 5 feet to the left of the middle of the screen? If so, would that effect the picture quality? I was about to go with a BenQ 7700 but now that I have read about the Sanyo Z4 and the Panasonic 900, the installation options and the picture quality have me leaning heavily toward either LCD models. If I could put the Sanyo way off to the side, it would help my problem room immensely! Any input would be greatly appreciated!
