Using the Lens Shift Adjustment

The projection lens can be moved up, down, right, and left with the motor-driven lens shift function. This

function makes the positioning of images easy on the screen. Lens shift is generally expressed as a

percentance of the image height or width, see below illustration.

No offset is applied - 0% offset.

Half of the image appears above lens

center and half of the image appears

below lens center.

Image has been offset 720 pixels above

lens center, so the center of the image is

now 720 pixels above where the center

of the image was at 0% offset (or lens

center).

The offset is +720/600 * 100% = +120%
