Adjusting lens settings

Adjust various lens settings including the offset, zoom, focus, and locking the lens motor.

Adjusting offset

Always adjust offset before adjusting boresight.
For the best optical performance and minimal keystone, use offsets instead of aiming at the center of
the image, in off-axis installations. Avoid extreme tilts or offsets. Corner vignettes on a white test
pattern indicate extreme offset that should be avoided using mechanical alignment.
1. Project an image with the primary lens.
2. Select a framing test pattern.
3. Select LENS OFFSET.
4. Use the arrows to adjust the offset to display a square image on the screen, with minimal
projector aiming error.
5. To exit to the home page, select Back.

Resetting the lens to home position

Set the lens offset back to the home position.
1. Select LENS OFFSET.
You can also select MENU > Configuration > Lens Settings > Lens Offset.
2. To reset the lens to the default home position, select Enter.
3. To confirm the reset, select OK.

Aligning the image with lens zoom and focus

Ensure that the image reflected from the digital micromirror device (DMD) is parallel and centered
with the lens and screen.
1. Display an image or test pattern that can be used to analyze image focus and geometry.
2. Select ZOOM.
3. Use the up and down arrows to zoom in or out of the image.
4. To exit, select Back.
5. Select FOCUS.
6. Use the up and down arrows to adjust the focus of the image.
7. To exit, select Back.
