3.5.5 Adjusting Color Balance
Color Balance is used to match the colors of adjacent displays when several GX40s are arranged in an array. You
may also use it to adjust the color of a single display.
For one GX40 only
If you have only one display, the Color Balance controls
can be used to set the color temperature of the single dis-
play.
To access the Color Balance menu, on the Remote press
once :

Understanding Color Temperature
Different "Pure white" light sources do not always have
the same color. For instance, light from an incandescent
bulb is much more yellowish than light from direct sun-
light. "Color Temperature" is a way of measuring these
color differences. In general higher color temperature num-
bers are more bluish or "cooler". You may have a reason for
wanting your unit to be a specific color temperature. For
instance, if you are using the GX40 in a television studio
where you will be videotaping the content, you will want a
low color temperature. The default color temperature for
the GX40 is 8500k. This is the native color temperature of
the LCD panel. You may choose a different color tempera-
ture by setting it in the Color Balance menu.
Adjusting Color Temperature
Select Color Temperature in the Color Balance menu
and select from 3200°K (Warm), 5500°K, 6500ºK, and
8500°K (Cool).
Each of these selects a set of White Balance values to
give the picture a warm (3200K) to cool (8500K) appear-
ance.

To adjust an array of GX40s for Color Balance
10 0 ( 10 0)
The object of color balancing is to make the individual
units in an array show the same colors. When we see a yel-
10 0 ( 10 0)
low car move across a video array from one display to
another, we want it to have the same color for the whole
10 0 ( 10 0)
trip, not change from yellow to tan to orange.
The displays naturally have slightly different colors
from one display to the next, because of slight variations in

the ands. This cannot be avoided, but we can compensate
for it with color balancing.

Color balancing is subjective. It may seem strange at
7
( 7)
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.
When you make all the displays look the same with
White and Gray, all the other colors will look the same. It is
not necessary to achieve a perfect white or a perfectly col-
orless gray. It is only necessary that all the displays look
alike when they display white and gray.
