Adjust Offset; Adjusting Left/Right Boresight - Christie CP2000-ZX User Manual

2.8.1 Adjust Offset

Project an image with the primary lens only. Always adjust offset before boresight. Important! Ensure the
correct lens is selected in the Advanced: Lens menu before calibration to ensure you will remain within the
applicable boundary of the installed lens. NOTE: When adjusting the Focus, Offset, and Zoom, you may
experience a slight delay in the response rate of the lens upon selecting the buttons.
1. From the Main menu, click ILS.
2. Ensure Automatic ILS is selected. See Figure 2-23. NOTE: Enabling Automatic ILS will over-write the
pre-defined settings for this channel. To perform a temporary lens adjustment, uncheck Automatic ILS and
adjust the lens by clicking the necessary buttons or manually adjusting the focus, offset, and/or zoom
knobs. All temporary adjustments will be lost when Automatic ILS is selected again or if the channel
changes.
3. Using the framing test pattern, adjust the Offset by clicking the up/down/left/right buttons on the ILS
menu (Figure 2-23) as necessary to display a square image on the screen. NOTES: 1) You can also hold
the buttons down for continuous movement. A pending status message appears on screen until the changes
have been applied. 2) For best optical performance, make sure to minimize keystone error by using offset
more than aiming to center the image in off axis installations. 3) Avoid extreme tilts or offsets. Corner
vignettes on a white test pattern indicates extreme offset that should be avoided using mechanical
alignment.

2.8.2 Adjusting Left/Right Boresight

The goal for left/right boresight alignment is to adjust the lens mount
until both sides of the image focus on the screen simultaneously.
Projectors are aligned properly at the factory, but due to mechanical
tolerances in the alignment between the projector and the screen, the left
and right sides of the image come into focus at different times. By
focusing on the left side of the screen, we need to determine if the right
side of the image focuses in front or behind the screen relative to the left
side. NOTE: Use a test pattern with a single pixel vertical and
horizontal line and perimeter frame such as DC2K Framing or RGB
Alignment.
