CAUTION
Never try to match the colors of the display
units with the Black and White Level controls
or with the Video Controls. You will not like the
results if you do.
CAUTION
If you are color blind, even a little bit, do not do
color balancing. Have someone else color bal-
ance the wall.
Color Balancing
1. Turn on all the units in the array and let them warm up
for at least five minutes. The backlights must be thor-
oughly warm before you color balance.
2. Open the Backlight Control and Status menu (

✎
If the array has never been color balanced, make
sure you start with the same color temperature
setting on each unit. If you are not interested in
achieving a specific color temperature, use the
default of 8500K, which is the brightest. If the unit
has been color balanced before, it will display
C
in its color temperature setting, because
USTOM
the balance values don't match any of the pre-set
color temperatures.
b) Highlight Test Pattern and use the left-right arrow
keys until it says White.
✎
Always use the internal Test Patterns for color
balancing, not an external pattern.
4. When all displays are white, find the least bright dis-
play in the array. This will be the "baseline" display,
and you will not adjust it. All other displays will be
adjusted to this baseline display.
✎
Why pick the "least bright" display? Why not pick
the brightest and adjust to it? When the White
value is 100, the display is as bright as it can get.
You are adjusting for slight variations in backlight

brightness.
5. Choose a display next to the baseline display and adjust
3 0
its White values (red, green, and blue) to make it match
the baseline display. Concentrate on the center of the
displays, not the adjacent edges. (If you can't bring the-
ses settings down to match the baseline, maybe you
didn't choose the darkest display.) Do not adjust the
Gray values at this time.
6. Continue with other adjacent displays until all the dis-
plays have the same appearance when white. Be careful
not to change the values of displays once you are satis-
fied with them. Use Hide Menu to keep from setting
other displays and allow you to see more of the white
field. To unhide the menu, press E

The menus will automatically turn off after a time
determined in Menu Options (

Menu Timeout is 0 (zero), the menus stay up
indefinitely.
