4.11 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 CP4220 via an Ethernet or RS-
232 connection.

4.12 Color Calibration

To ensure an accurate color display:
1. Measure the colors displayed on the screen from the center of the audience viewing location to determine
the Measured Color Gamut Data (MCGD) value.
2. On the Touch Pad Controller tap Menu > Advanced Setup > MCGD File Setup and enter the color
values in the x and y fields for the different colors.
3. Tap Save. The software automatically determines the Target Color Gamut Data (TCGD) value. The TCGD
value determines what corrections are needed to display the correct colors.

4.13 Electronic Screen Masking

You can use the masking tool to correct image edge blanking. The masking tool produces results that are
similar to filing the aperture plate in a film projector. After you create the Flat and Scope screen files you can
use them in multiple channels.

4.14 Working with 3D

This section provides information and procedures for setting up and managing 3D presentations.

4.14.1 Display Requirements

To display 3D images with the CP2220 projector, you require these items:
• A 3D hardware system:
• Pi-Cell polarizer for display on a screen that has a silver polarization-preserving surface for use with pas-
sive glasses (RealD).
• Rotating polarizing wheel (external) with passive circular polarizing glasses (MasterImage). Requires a
silver screen.
• IR emitter for controlling the left eye/right eye gating (switching) of active glasses (Xpand).
• Dual projector 3D - passive glasses (circular or linear). Requires a silver screen.
• A 3D connection cable:
• 3D sync output cable (GPIO).
• 3D connector.
• Power supply for your sync output device.
