Adjust Left/Right Boresight - Christie CP2000-SB Setup Manual

Section 3: Installation & Setup
The maximum vertical offset is shown in Figure 3-38 (bottom illustration). NOTES: 1) Horizontal offset is
just a few dozen pixels, resulting in a maximum of 52% of the image displayed on one side or the other of the
lens. 2) Maximum offsets are slightly less when offsetting in both directions (H and V) at once.

3.9.2 Adjust 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.
1. The Horizontal Hold Screw acts as counter-resistance to hold the lens mount in place once set. Before
adjusting the boresight, loosen the Horizontal Hold Screw. See Figure 3-39.
2. Extend the lens focus completely.
