Lens Shift Adjustment; Vertical / Horizontal Lens Shift - Eiki EIP-UHS100 Owner's Manual

Lens Shift Adjustment

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

Vertical / Horizontal Lens Shift

For ceiling mounted projectors, the lens can be moved 50% (0.5V) downward, while the
lens can be moved 50% (0.5V) up or down on a desktop mounted projector.

This is a general example of lens shift. Lenses vary in their shift capabilities. No particular lens or projector is

When the lens is shifted beyond the described range of operation, the screen edges may become darker or
the images may become out of focus.
