Color Balancing Multiple Displays
62 m52L Installation Guide
4 If the array has never been color balanced, make sure you start with the
NATIVE
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.
5 On each display, highlight
TEST PATTERN
and use the left or right arrows until the
menu displays
WHITE
.
Note: Always use the internal Test Patterns for color balancing, not an external pattern.
6 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.
7 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 these settings down to
match the baseline, maybe you didn’t choose the darkest display.) Do
not adjust
the gray values at this time.
8 Continue with other adjacent displays until all the displays have the same
appearance when white. Be careful not to change the values of displays once you
are satisfied with them. Select
HIDE MENU
to keep from setting other displays and
allow you to see more of the white field. To unhide the menu, press
ENTER
.
Note: The menus will automatically turn off after a time determined in the
MENU OPTIONS
menu (
MENU
>
ADVANCED OPTIONS
>
MENU OPTIONS
>
MENU TIMEOUT
). If
MENU
TIMEOUT
is set to
NEVER TIME OUT
, the menus stay up indefinitely.
9 When all displays look the same when displaying the White test pattern, choose
the Gray test pattern in all displays.
10 Choose any display as the new baseline display. It does not need to be the
baseline display you used for white.
11 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.
12 When all displays match in gray, close all the menus. The test pattern
automatically turns off.
