COLOR BALANCING A WALL OF PMCD750 DISPLAYS
Color balancing will make the individual units within a wall show uniform colors. This can be performed before or after adjustment of the input
levels.
The following procedure is required for all units in a wall system.
To adjust the color balance for a wall, refer to Figure 16 and do the following:
1. Make sure the lamps in each unit have warmed up for at least five minutes. The lamps must be thoroughly warm before color balancing.
2. For each display, press MISC once on the remote.
NOTE: If the wall has never been color balanced, make sure you start with the same color temperature setting on each display. If you are not
interested in achieving a specific color temperature, use the default of 8500°K, which is the brightest. If the display has been color balanced
before, it will display Custom in the Color Temperature setting, because the balance values do not match any of the preset color temperatures.
3. Scroll down to Color Temperature. Press ENTER on the remote to choose one of the color temperatures. The choices are 3200°K, 5500°K,
6500°K, and 8500°K.
4. Scroll down to Gamma. Press ENTER to change this setting to Video (optimal brightness) or Film (deeper reds). Use the same setting for all
displays in the wall.
5. Scroll down to White Boost. Press ENTER to change this setting to Off.
6. Scroll up to Test Pattern. Press ENTER to change the setting to White.
NOTE: Always use the internal test patterns for color balancing, not an external pattern.

7. Check the color balance values for all displays. All white balance values should be 100, and all Gray balance values should be 7. If any of
these values vary from these levels, scroll down to Reset to Defaults and then press ENTER on the remote. This is the correct starting point
for color balancing.
8. On each display, scroll down to Hide Menu and then press ENTER. This will remove all menus so that the entire wall can be seen as a
whole. To reopen the Color Balance menu, aim the remote at the desired display and then press ENTER.
