3.3.7 Adjusting Color Balance
Color Balance is used to match the colors of adjacent displays when several Bay Cats are arranged in a
wall. You may also use it to adjust the color of a single display.
For one Bay Cat only
If you have only one display, the Color Balance
controls can be used to set the color temperature of
the single display. Select Color Temperature in the
Color Balance menu and select from
• 3200K
• 5500K
• 6500K
• 9500K
Each of these selects a set of White Balance and Gray
Balances values to give the picture a warm (3200K) to
cool (9500K) appearance.
To adjust a wall of Bay Cats for Color Balance
Open the
Backlight Control and Status
menu (
MENU
>
A
DVANCED
O
PTIONS
> B
ACKLIGHT
C
ONTROL
& S
TATUS
).
a) Set
Backlight Mode Control
to
Manual
.
b) Set
Backlight Intensity
to 100%.
1. Open the
Color Balance
menu on all displays in
the wall. (
MENU
> A
DVANCED
O
PTIONS
> C
OLOR
B
ALANCE
).
a) Select
Color Temperature
at the top of the
menu and press the left or right arrow to get to
Custom
.
b) Highlight
Reset to Defaults
at the bottom of
the menu and press
ENTER
.
c) Highlight
Test Pattern
and use the left-right
arrow keys until it says
White
.
2. Do the previous steps on al l Bay Cats in the wall.
3. When all displays are white, find the least bright
display in the wall. This will be the “baseline” dis-
play, 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 a bright as it can get. You are adjusting for
slight variations in backlight brightness.
4. Choose a display next to the baseline display and
adjust 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 theses settings down to
match the baseline, maybe you didn’t choose the
darkest display.) Do
not adjust the Gray values at
this time.
5. Continue with other adjacent displays until all
the displays have the same appearance when
white. Be careful not to change the values of dis-
plays once you are satisfied with them. Cover the
remote control holes (lower left corner of bezel) to
prevent this, or turn off the menus.
The menus will automatically turn off after a time
determined in Menu Options (
MENU
> Advanced
Options > Menu Options > Menu Timeout
). If Menu
Timeout is 0 (zero), the menus stay up indefinitely.
6. When all displays look the same for White,
choose the Gray test pattern in all displays.
7. Choose any display as the new baseline display. It
does not need to be the baseline display you used
for White.
8. Adjust all the displays in the Gray part of the Test
Patterns menu until they match the baseline dis-
play. Do one display at a time. Again, match the
center part of the picture, not the edges.
9. When all displays match in Gray, turn off all the
Test Patterns and close all the menus.
Tips for color balancing
• Removing red has the same effect on hue as
increasing blue and green together. The Color Bal-
ance menu slider bars have colored bulbs at each
end to tell you what the effect will be of moving a
color toward that end.
• Stand back from the display wall and directly in
front of it to get the overall view.
• Small changes are difficult to see at first, particu-
larly with White. Change the value by 4 or 5 steps
to see the difference. If you are going the wrong
way, go back and move it 4 or 5 steps in the other
direction. If neither of these bring you closer to a
match, try another color.
• When you don’t know which color to change, pick
one at random and change it 3 or 4 steps. The
result will be either better or worse. If worse, go
the other way with that color. If that is also worse,
put this color back where you started and to the
same with another color. If everything you do
makes the match worse, you must be close to the
ideal point.
