Adjusting Dmd Convergence; Adjusting The Fold Mirror - Christie CP2308-C Installation And Setup Manual

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 accredited service technician to correct DMD convergence issues.
