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.

Adjusting DMD convergence

A convergence problem occurs when one or more projected colors (red, green, blue) appears
misaligned when examined with a convergence test pattern.
Normally, the three colors should overlap precisely to form pure white lines throughout the image and
one or more poorly converged individual colors may appear adjacent to some or all of the lines.
Contact your Christie qualified service technician to correct DMD convergence issues.

Correcting on-screen color

After installation, further image adjustments may be required to correct color on the screen.
The next steps may include creating a Measured Color Gamut Data (MCDG) file and configuring a
™
Pureformity Color Technology (PCT) file to achieve optimal color and brightness uniformity.
