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.

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.

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.
