Adjust Dmd Convergence; Align The Fold Mirror - Christie CP2215 User Manual

10. Each corner of the screen should be equally in focus when horizontal boresight is completed
correctly. If necessary, repeat vertical boresight. Only adjust vertical 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 each turn of the cap screws is counted to make sure the adjustments
are accurate.

Adjust 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.

Align the Fold Mirror

If a corner or edge of an image is missing, the fold mirror might be misaligned with the optical
system. To correct this issue:
1. Remove the top lid and set it aside.
2. Display a full white test pattern:
a. On the TPC, tap the Test Pattern icon (
b. Tap All Test Patterns.
