Knoll Systems LED1081 user manual Vertical Lens Shift

Lens Shift

The LED1081 has a lens shift capability which allows the vertical movement of the image without moving the projector.

Lens shift is generally expressed as a percentage of the screen height. For ceiling mounted projectors, the lens can be moved 120% (0.6V) downward, while the lens can be moved 120% (0.6V) up or down on a desktop mounted projector.
