4.7 Adjust DMD Convergence

UV EXPOSURE! Protective UV glasses must be worn when performing

convergence adjustments.

A convergence problem occurs when one or more projected colors (red, green, blue) appears misaligned when

examined with a convergence test pattern. Normally, the three colors should overlap precisely to form pure

white lines throughout the image and one or more poorly converged individual colors may appear adjacent to

some or all of the lines. Contact your Christie accredited service technician to correct DMD convergence

issues.

4.8 Fold Mirror Adjustment

If a corner or edge of an image is missing, the fold mirror might be misaligned with the optical system. To

correct this issue:

1. Unlock the two set screws (Figure 4-5/B).

2. Turn the pivot screw 90-180° (Figure 4-5/C).

3. Adjust both cap screws (Figure 4-5/A).

4. Tighten the two set screws and pivot screw when you have aligned the fold mirror correctly.

4.9 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.
