Lens Shift
The H9080FD 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.
