Shifting The Projection Lens - BenQ Home Entertainment Series User Manual

Shifting the projection lens

The lens shift lever at the front side of the projector provides flexibility for installing your projector. It allows the
projector to be positioned off axis from screen center.
The lens shift (offset) is expressed as a percentage of the projected image height or width. It is measured as an
offset from the projected image's vertical or horizontal center. The W500 is equipped with + 110% vertical lens
shift and + 48.8% horizontal shift. You can use the joystick to shift the projection lens in any direction within the
allowable range depending on your desired image position.

• The lens shift lever can be secured by turning it clockwise or released by turning it counterclockwise.
