Adjusting the image
Learn how to adjust image geometry so it displays correctly.
Activating the Intelligent Lens System
Activate the Intelligent Lens System (ILS) to automatically adjust the position of the lens.

2. Tap Lens/ILS.
3. In the right pane, tap the ILS Installed slider.
The color of the slider changes to green to indicate the ILS is active.

2. Tap Create.
3. Type a name for the ILS file and tap Create.
4. Tap Auto Calibrate.
5. Tap Continue.
Correcting vignetting
An image that is brighter at the center than it is at the sides needs vignetting correction.
If your image suffers from vignetting, the lens has reached the end of its offset travel range. If your
installation does not allow the image to be centered with the center of the screen, move the entire
projector in the direction of lens travel.
Correcting keystone effect
Learn how to adjust the image to correct keystone effect.
Keystone effect occurs when you project an image onto the screen at an angle. As a result, the image
appears distorted and resembles a trapezoid.
If the image suffers from slight keystone effect, it can be corrected with electronic cropping.
If the keystone effect is severe, you can unevenly adjust the feet to compensate for projector tilt. It is
recommended that you use lens offset to align the center of the image to the center of the screen
before you correct the keystone effect.
