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,
1 Reset 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
e Select COLOR TEMPERATURE and set it to USER.
2
Using either a meter or your eye, find the dimmest unit. You must adjust all
the other displays in the wall to match this one.
3 Adjust the backlight levels of all the other displays to match as closely as
possible to this dimmest display.
4 Use 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 (left-or-right or
above-or-below).
5 Display a 50% gray screen by lowering the backlight values, and adjust the
RGB OFFSETS so they match.
6 Match the brightness again with the backlight controls.
