Adjust DMD Convergence

DANGER
convergence adjustments.
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.

4.10 Fold Mirror Adjustment

If a corner or edge of an image is missing, the fold mirror might be misaligned with the optical system. To
correct this issue:
• Adjust the screw closest to the operator's side (right side, when facing screen) to raise or lower the image.
• Adjust the screw on the left side to move the image left or right.
