Color Balancing the
VideoWall/CineWall
What does Color Balance do? Color balancing is the process of ensuring that whites
appear truly white and grays appear truly gray, without any trace of color.
Displays differ from one another because of very small differences in the color of the light
produced by the lamp and by differences in the dyes used to make the color in a DLP™
optical engine.
In color balancing, you use the display’s internal test patterns of white, first, then gray. The
internal pattern assures that a pure white is used.
1. Turn on the VideoWall/CineWall and let it warm up for at least five minutes. The lamp
must be thoroughly warm before you color balance.
2. Press MENU on the remote control and enter the Installer Menu passcode. To obtain
this passcode, contact Runco Technical Support.
3. Select Advanced Options from the Main Menu.
4. Select Color Balance from the Advanced Options menu.
5. Set Gamma at the bottom of the menu to either Video or Film.
6. Set the Color Temperature to 6500K.
7. Set White Boost to Off.
8. Set Test Pattern to White.
9. Look at the Color Balance values. All the White Balance (Gain) values should be 100,
and all the Gray Balance (Offset) values should be 8. If they are not, select Reset to
Defaults and press ENTER. This is where you should always start color balancing.
10. Stand far enough away from the screen so you are looking almost squarely at it. Pay
attention to the large central area, not the edges.
11. Using an optical comparator or other D6500 reference – or a color analyzer – adjust
the White Balance values either individually or together (using the “All” slider) to
achieve a neutral, D6500 white point.
12. Set Test Pattern to Gray.
13. The gray values range from 0 to 15, and they are all now set at 8. Adjust them up or
down as needed to eliminate any trace of color from the test pattern.
14. When you have finished color balancing, set Test Pattern to None.
Although it may be possible to achieve satisfactory results using the
naked eye, it is recommended that you use a computer-based color
analyzer (Sencore ColorPro 5000 software and ColorPro III sensor,
or equivalent), hand-held colorimeter or ISF optical comparator to
color balance the VideoWall/CineWall. For more information, visit

Always use the internal Test Patterns for color balancing, not an
external pattern.
