4. Ideally, the image should be centered on the lens and if it is not aligned to the screen in case,
start by physically moving the projector; however, if not possible, use the lens shift.
5. With the Framing test pattern on screen, re-check the projector leveling so the top edge of the
image is parallel to the top edge of the screen.
Adjusting offset by using an ILS
Learn how to adjust the offset by using an ILS (Intelligent Lens System).
Always adjust the offset before adjusting boresight.
As boresight is adjusted, the lens offset may require additional minor adjustments.
1. Project an image with the primary lens.
2. Make sure lens calibration is completed before creating the ILS file.
3. Select Test Patterns and select a framing test pattern.
4. In the left navigation menu, select Image Settings > ILS File Setup.
5. Select the directional arrows in the Offset area.
For best optical performance, make sure to minimize keystone error by using the offset more
than aiming to center the image in an off-axis installation. Avoid extreme tilts or offsets.
Corner vignettes on a white test pattern indicates extreme offset that should be corrected by
using mechanical alignment.
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
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.
When making the adjustments, set the light source to minimum power.
