Adjust Offset; Adjust Offset With An Ils; Adjust Left And Right Boresight - Christie CP4230 User Manual

Section 4: Adjust the Image
4.4

Adjust Offset

Project an image with the primary lens. Always
adjust offset before boresight.
Select a framing test pattern and then adjust the
horizontal and vertical offset to display a square
image on the screen with minimal projector
aiming error.
NOTES: 1) For the best optical performance
and minimize keystone error, use offset and not
aiming to center the image in off axis
installations. 2) Avoid extreme tilts or offsets.
Corner vignettes on a white test pattern indicate
extreme offset that should be avoided using
mechanical alignment.
4.5

Adjust Offset with an ILS

Project an image with the primary lens. Always
adjust offset before boresight. Ensure the
correct lens is selected in the Advanced Setup:
Lens Adjust window before calibration to ensure you remain within the applicable boundary of the installed
lens.
1. Tap Menu > Advanced Setup > Lens Setup.
2. Tap Enable Automatic ILS. Enabling Automatic ILS overwrites the pre-defined settings for the channel.
3. Tap the Test Patterns icon and select a framing test pattern.
4. Tap Menu > Advanced Setup > ILS File Setup.
5. Tap the directional arrows in the Offset area. For best optical performance, make sure to minimize
keystone error by using offset more than aiming to center the image in off axis installations. Avoid extreme
tilts or offsets. Corner vignettes on a white test pattern indicates extreme offset that should be avoided
using mechanical alignment.
4.6

Adjust Left and Right Boresight

When performing these adjustments the goal is to balance the tilt of the lens mount to compensate for screen to
projector tilt, but also to precisely maintain the original factory settings of the lens mount axial position.
1. Loosen the horizontal hold screw.
2. Extend the lens focus completely.
