4.11 Calibrate the System

Use the TPC to calibrate the image color performance and define 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 cinema projector and transmit information to and from the CP4230 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 cinema projector. After you create the Flat and Scope screen files
you can use them in multiple channels.

4.14 Work 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 CP4230 cinema projector, you require these items:
• Two HD-SDI cinema signals (left and right) connected to the cinema projector's SMPTE ports HD-SDI A
and HD-SDI B.
• 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 cinema 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.
