Shifting The Projection Lens Vertically - BenQ Home Cinema Series User Manual

Shifting the projection lens vertically

The vertical lens shift control provides flexibility for installing your projector. It allows the projector to be
positioned slightly above or below the top level of the projected images.
The lens shift (offset) is expressed as a percentage of the projected image height. Use the wheel to shift
the projection lens upwards or downwards within the allowable range depending on your desired image
position.

Lens shift adjustment does not result in a degraded picture quality. In the unlikely event that the image
distortion is produced, see Adjusting the projected image for details.
