14 Setting Up the Projector
Ideally, place the projector at a height where its lens is between the top and bottom of the
screen. That way, you can keep the projector level and use the vertical lens shift dial to
position the image. This produces the best-looking picture.
Try to be as close as possible to the calculated projector position when installing the projector.
Too much lens shift can cause minor reduction in image dimensions. The image display
position cannot be moved to the maximum distance in both the vertical and horizontal
directions. For example, the image cannot be shifted vertically when it has been shifted
horizontally by the full amount. When the image has been shifted vertically by the full
amount, it can be shifted up to 9 percent of the horizontal width of the screen.
If you place the projector off to the side, aim it straight ahead (rather than at the center of the
screen), then use the horizontal lens shift dial to center the image on the screen.
Caution: Do not try to move the lens by hand, or you may damage the projector. Always use the
lens shift dials to change the lens position.
