Calibrating the System

It is recommended the web user interface is used for:
• calibrating image color performance
• defining electronic screen masking
• creating individual Projector Configuration Files (PCFs)
• creating specific source files, necessary for proper display of incoming material
The web user interface also enables users to define the system/network configuration for communication links
to the projector.

2.8.1 Color Calibration

After the CP2000-M/MR is installed and all components are mechanically aligned for optimized light output
and geometry at the screen, its electronic system processing must be calibrated to ensure accurate color display
in the new environment. In this one-time global calibration, the installer measures initial colors at the screen
from the center of the viewing audience location, also called SMPTE reference area and enters this data—
called Measured Color Gamut Data (MCGD)—into the web user interface. NOTE: The SMPTE reference
area for image measurements is the center of the seating area. SMPTE reference for audio is 2/3 the length of
the auditorium.
The software then calculates the precise corrections needed for regaining the desired color performance —
called Target Color Gamut Data (TCGD) — and essentially compensates for the type of port window (if
present), screen, lens, light output, ambient light and other current environmental factors that affect color
performance. Results are defined in a file, activated and downloaded to projector memory to be used as a basis
for future displays.
If there are future environmental changes (for example, a new screen is installed), the CP2000-M/MR should
be re-calibrated. Correction for proper color balance sometimes reduces overall light output. NOTE: Onsite
(MCGD) files are not provided with the projector and must be created by the installer. Multiple gamut files
should be saved for use in different situations, such as when an auxiliary lens is swapped on and off the
projector. These saved gamut files are accessible from the Channel: Page 2 menu on the web user interface or
from the CDP Channel>Edit Channel>Measured Color menu.
