Section 2: Installation and Setup

2.13.2 Color Gamut Adjustment

For the widest color gamut, install the Yellow Notch Filter (optional) inside the projector, near the lens
opening. Adjust to match a known standard, such as x=0.265, y=0.690, or as desired. In applications where
maximum brightness is preferred over increased color gamut, do not add the Yellow Notch Filter (this is the
factory default).

2.13.3 Maximizing Brightness

Do not use either the optional Yellow Notch Filter or a small-diameter high-contrast F# Aperture option in the
projector to achieve maximum brightness. This is the factory-default configuration. Also, make sure a
standard high-brightness lens is used.

2.13.4 DMD Convergence

A convergence problem is evident when one or more projected colors (red/green/blue) appears misaligned
when examined with a proper convergence test pattern. Normally the 3 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. A Christie accredited service technician can correct as described on the
color Convergence Instructions label provided inside the projection head.
NOTE:
Custom Convergence Kit required (available separately).

2.13.5 Fold Mirror Adjustment

If a corner or edge of an image is missing, this may indicate that the fold mirror has become misaligned with
the rest of the optical system and cannot reflect all data properly.
Correct as described below:
1. Locate the fold mirror access plate
secured to the underside of the
projection head, just below the lens. It
has 2 access holes along the front
edge, through which you can
carefully adjust the fold mirror
screws
• To raise or lower the image, adjust
the screw closest to the left side
(exhaust side of projector).
• To move the image left or right,
adjust the screw closest to the right
side (lamp side).
Proper fold mirror adjustment is shown in
projected edges of the integrator.
