Adjusting Color Balance
Runco WindowWall Installation Guide 63
5
If the array 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
NATIVE
, which is the brightest. If the display has
been color balanced before, it will display
CUSTOM
in the
COLOR TEMPERATURE
line, because the balance values don’t match any of the pre-set color
temperatures.
6
Highlight the
WHITE TEST PATTERN
line and press
ENTER
. This will show the white
test pattern on all displays.
Note: Always use the internal Test Patterns for color balancing, not an external pattern.
7
When all displays are white, find the least bright display 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.
8
Choose a display next to the baseline display and adjust its
BACKLIGHT
ADJUSTMENT
to make its overall brightness match the baseline display. (If you
can’t bring this setting down to match the baseline, maybe you didn’t choose the
darkest display.)
9
Continue with other adjacent displays until the overall backlight brightness
matches on all displays.
Note: The backlight adjustment does not affect the color of the display.
10
Choose a display next to the baseline display and adjust its white values (red,
green and blue) to make its color match the baseline display. Concentrate on the
center of the displays, not the adjacent edges. Do
not adjust the gray values at
this time.
11
Continue with other adjacent displays until all the displays have the same
appearance when white.
12
When all displays look the same when displaying the White test pattern, highlight
the
GRAY TEST PATTERN
line and press
ENTER
. This will show the gray pattern on
all displays.
13
Choose any display as the new baseline display. It does not need to be the
baseline display you used for white.
14
Adjust the gray values for all the displays until they match the baseline display.
Do one display at a time. Again, match the center part of the picture, not the
edges.
