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.
Vertical lens shift
Horizontal lens shift
The lens shift lever can be secured by turning it clockwise or released by turning it counterclockwise.
Please be careful to not over-tighten it.
Lens shift adjustment will not result in degraded picture quality. In the unlikely event, image distortion
was produced. If so, see "Adjusting the projected image" on page 26 for details.
