2.10 Calibrating the System

Use the TPC interface for calibrating the image color performance and defining electronic screen masking.

This is required in your particular installation for the creation of Source, Screen, MCGD and TCGD files

necessary for proper display of incoming material. You can also define the system/network configuration for

communication links to the projector and transmit information to and from the CP2210 via an Ethernet or

RS232 connection.

After the CP2210 is installed and all components are mechanically aligned for optimized light output and

geometry, 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 seats, and enters this data—called Measured

Color Gamut Data (MCGD)—into the TPC interface. The software then calculates 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 the projector memory to be used as a basis for all future displays.

If there are changes to the environment in the future (for example, a new screen is installed), the CP2210

should be re-calibrated. Also note that 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 in

the Advanced Setup: MCGD File Setup window. Multiple gamut files can 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 for each channel in the Channel Setup: Config 2 window.

Image edge blanking can be corrected using the masking tool for precision cropping in the Advanced Setup:

Screen File Window. The effect is similar to aperture plate filing typically done for correcting images from film

projectors. NOTE: The Flat and Scope Screen files are not provided with the projector and must be created by

the installer. Once created, these files can be used for multiple channels, which are accessible in the Channel

Setup: Config 1 window for each channel.
