Color Balancing the Wall
If you have only one display, you do not need to go through this section. If you have a wall of displays, you will want them to display the same colors throughout the wall.
Color Temperature
Different “pure white” light sources do not always have the same color. For instance, light from an incandescent bulb has more yellow than light from direct sunlight. “Color Temperature” is a way of measuring these color differences. In general, higher color temperature numbers are bluer or “cooler.”
To adjust Color Temperature,
1Reset all the displays to a nominal value. For each display in the wall, do the following:
a Press the MENU button to display the menu on the screen. b Select PICTURE and press OK.
c Select BACKLIGHT and press OK. Adjust Backlight to 80. d Select COLOR BALANCE and set
•all three GAINS to 50
•all three RGB GAINS to 100
•all three RGB OFFSETS to 50
eSelect COLOR TEMPERATURE and set it to USER.
2Using either a meter or your eye, find the dimmest unit. You must adjust all the other displays in the wall to match this one.
3Adjust the backlight levels of all the other displays to match as closely as possible to this dimmest display.
4Use the RGB GAIN of each display to make the colors match.
a Choose one of the displays that looks “whitest” and match the others to this one. Always match a display to one that is next to it
5Display a 50% gray screen by lowering the backlight values, and adjust the RGB OFFSETS so they match.
6Match the brightness again with the backlight controls.
