Positioning your projector20

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 half height. It is

measured as an offset from the projected image’s vertical center. You can shift the

projection lens within the allowable range depending on your desired image position.

Lens shift adjustment will not result in a degraded picture quality. In the unlikely event that the

image distortion is produced, see "Correcting keystone" on page 33 for details.
