Adjust Vertical Boresight Angle

A boresight adjustment should only be made when the image cannot be focused uniformly
on the screen by aligning the projector to the screen and focusing the lens. When adjusting
boresight, you must maintain the boresight distance from the lens to the prism plane set by
Christie. For example, when you move the top screw outward, turn the bottom two
boresight screws to maintain the overall distance.
Only adjust vertical boresight 1/8 of a turn or less at one time to maintain optimal lens
performance (such as factory setup of absolute lens distance to the prism). Each turn of the
cap screws must be tracked to ensure adjustments are accurate.
It is recommended that you complete a top and bottom boresight adjustment before adjusting the
horizontal boresight.
1. Display the DC2K Framing2 test pattern:
a. On the touch panel controller (TPC), tap the Test Pattern icon (
b. Tap All Test Patterns.
c. Tap DC2K Framing 2.
2. Loosen the set screw (B).
3. Turn the vertical cap screw (A) 1/8 of a turn counter-clockwise.
4. Adjust both left and right horizontal adjusters by half the number of turns, in the opposite
direction of the vertical adjust. For example, if the vertical adjust cap screw was turned 1/8 of a
turn, the left and right horizontal cap screws should be turned 1/16 of a turn in the opposite
direction.
