3.10 Fold Mirror and Convergence Adjustments

In rare instances, shipping and handling may affect the precise factory alignments of one or more optical
components—as a final step of installation, the installer may have to adjust the fold mirror and/or convergence
of the DMDs as described here.

Fold Mirror Adjustment

If a corner or edge of the image is missing, this may
indicate that the fold mirror has become misaligned
with the rest of the optical system, resulting in
cropping of data. Correct as described below:
Remove the fold mirror access plate from the
underside of the projection head—this plate is located
just below the lens. Two access holes will be revealed,
through which you can adjust two fold mirror screws:
• To raise or lower the image - adjust the screw clos-
est to the operator's side.
• To move the image left or right - adjust the screw
furthest from the operator's side.

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—where normally the 3 colors should overlap precisely
to form pure white lines throughout the image, one or more poorly converged individual colors may appear
adjacent to some or all of the lines. Qualified service technicians can correct as described on the color label
provided inside the projection head.

3.11 Calibrating the System Using DCP Librarian Setup Software

NOTE: DCP Librarian described here is licensed software intended for Christie installers only. Many of its
functions are now available at the TPC.
DCP Librarian is a comprehensive Windows-based software application used for calibrating image color
performance and defining electronic screen masking required in your particular installation, and for creating
individual Projector Configuration Files (PCFs) and specific source files necessary for proper display of
incoming material. DCP Librarian also defines the system/network configuration for communication links to
the projector, transmitting information to and from the CP2000 via an Ethernet or RS-232 connection. Chief
functions, many of which can be done at the TPC, are introduced below.
