Only adjust horizontal boresight 1/8 of a turn or less at one time to maintain optimal lens performance
(factory setup of absolute lens distance to the prism). It is critical that you count each turn of the cap screws
to ensure accurate adjustment.
Ensure that the boresight lockdown screws are adequately tightened. Not adequately tightening the boresight
screws can result in excessive onscreen image vibration. After adjusting boresight, evaluate the onscreen
image vibration and re-adjust if needed.
1.
Remove the lens surround.
2.
Display the DC2K Boresight test pattern.
3.
Loosen the right boresight set screw (B).
A
Right boresight cap screw
C
Left boresight cap screw
B
Right boresight set screw
D
Left boresight set screw
4.
Turn the right boresight cap screw (A) 1/16 of a turn clockwise.
5.
Adjust the left boresight cap screw (C) equally in the opposite direction.
6.
If the quality of the projected image has not improved, turn the right boresight cap screw 1/16 of turn
counter-clockwise. Make sure the left adjuster is adjusted equally in the opposite direction.
7.
Check the screen each time an adjustment is made. The right-side adjustments affect the top right
and bottom left points on the screen. Once both cross hairs are in focus, lock the set screw for right
boresight.
8.
Repeat steps 5 to 7 for the left side.
9.
Verify that each corner of the screen is equally in focus. If this is not the case, repeat vertical
boresight.
A digital micromirror device (DMD) convergence problem occurs when one or more projected colors (red,
green, blue) appears misaligned when examined with a convergence test pattern.
