Shifting The Projection Lens - BenQ W3000 User Manual

Shifting the projection lens

The lens shift control provides flexibility for installing your projector. It allows the
projector to be positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image width or height. It is
measured as an offset from the projected image's horizontal or vertical center. You can
shift the projection lens within the allowable range depending on your desired image
position.
