NOTE: Most gamut functions are also now available in the TPC Gamut menu
(password required). Multiple MCGD files can be saved for use in different
situations, such as when an anamorphic lens is swapped on and off the projector.
ELECTRONIC SCREEN MASKING:
tool for precision cropping of the image to correct for geometry problems such as a
keystoned image. The effect is similar to aperture plate filing typically done for
correcting images from film projectors. As in the calibration of color, screen masking
adjustments are global—that is, you can create a variety masks and download them to
projector memory for use with sources as desired. Mask settings are distinct from
aspect ratio or screen position settings.
NOTE: Most screen functions are also now available in the TPC Screen menu
(password required).
PCFs (rare):
Numerous settings collected into a single Projector Configuration File
further control processing variables for optimized display of specific source material.
Each PCF file, typically created in DCP Librarian, pre-defines color space, target
color gamut, source aspect ratio (resolution), and gamma (a.k.a. "degamma") settings
for a cinema or non-cinema source. Once the collected settings are downloaded to the
projector's internal memory, their "PCF" can be assigned to the corresponding
CP2000 input connection and quickly applied via a controller such as Christie's
Touch Panel Controller. No further adjustment in processing should be required.
Refer to the DCP Librarian User's Manual for all DCP Librarian Setup Software
operating details and procedures.
As a final step in any installation, adjust the ballast phases to minimize ripple from
the available AC. This will help eliminate on-screen flashing in mid-range grayscale
images. Refer to the 3-Phase Ballast Ripple Adjustment instructions supplied with the
projector.
Not applicable to CP2000-S models.
