Adjusting Color Balance
Color Balance is used to select the color temperature of each display, as well as to
match the colors of adjacent displays when several displays are arranged in an array.
When you see a yellow car move across a video array from one display to another,
you want it to have the same color for the whole trip, not change from yellow to tan
to orange.
Colors vary slightly from one display to the next, because of slight variations in the
backlights and displays. This cannot be avoided, but you can compensate for it with
color balancing.
Understanding 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.” You may have a reason for wanting
your display to be a specific color temperature. For instance, if you are using the
Runco WindowWall in a television studio where you will be videotaping the content,
you will want a low color temperature. The Runco WindowWall defaults to the
brightest setting possible, which is 100 in the
RED
,
GREEN
and
BLUE
lines under
WHITE BALANCE
. You may choose a different color temperature by setting it in the
COLOR BALANCE
menu.
Adjusting Color Temperature
Select the
COLOR TEMPERATURE
line in the
COLOR BALANCE
menu and then select
from 3200°K (Warm), 5500°K, 6500ºK, 8500°K (Cool) or
NATIVE
. If you want the
brightest display, select the
NATIVE
option.
Changing the color temperature changes the three
WHITE BALANCE
values. You can
also change the
WHITE BALANCE
values individually to create a custom color
temperature. Once you have changed the values, a new
CUSTOM
option is available
on the
COLOR TEMPERATURE
line.
Color Balancing Multiple Displays
Color balancing is subjective. It may seem strange at first, but it gets easier with
practice. Fortunately, you don't have to match all the colors; you only have to match
whites and grays. It is not necessary to achieve a perfect white or a perfectly colorless
gray. It is only necessary that all the displays look alike when they display white and
gray.
Caution: Never try to match the colors of the displays 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 color balance your array. Have
someone else color balance the wall.
