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

2.7.1 Adjust Offset

Project an image with the primary lens only. The optional
auxiliary lens mount, if present, can be mounted but swung aside.
Adjust horizontal and vertical offset as necessary to display a
square image on screen with minimal projector aiming error.
Always adjust offset before boresight. NOTE: For best optical
performance, make sure to minimize keystone error by using offset
more than aiming to center the image in off axis installations.

2.7.2 Adjusting Left/Right Boresight

1. Adjust focus at the far left center edge of the image.
If possible, reduce image size for easier image
analysis.
2. If the image appears well-focused on the left edge but
not on the right, then the boresight currently differs
from one side to the other - i.e., the right side of the
image is well-focused either in front of or behind the
screen surface rather than on it. If you have easy
access to the screen you can determine where the
right side is focusing by doing the following:
r Hold a piece of white paper approximately parallel
to the screen surface at the right side (and as close to
the vertical center as possible), then move closer to the
projector while watching the image on the paper.
• If focus on the paper improves, this indicates that
the right side of the image is focusing in front of the
screen.
• If focus on the paper worsens, this indicates that
the right side of the image is focusing behind the
screen.
GOAL: If the image comes into focus on both sides
simultaneously, left/right boresight is fine - skip Step 7.
