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 height or width. It is measured as an offset
from the projected image’s vertical or horizontal center. You can use the lever to shift the projection lens in
any direction within the allowable range depending on your desired image position.
To use the lens shift lever:
1. Release the lever by turning it counterclockwise.
2. Move the lever to adjust the projected image position.
3. Lock the lever by turning it clockwise.
Please do not over-tighten the lever.
Lens shift adjustment will not result in a degraded picture quality. In the unlikely event that the image
distortion is produced, see "Adjusting the projected image" on page 25 for details.
