Note
: The input level must
be adjusted before executing this procedure. The input
level adjustment has a large effect on color. Also, the input level adjustment
procedure must be executed for each source (that is, each processor,
computer, etc. in the system) prior to proceeding with color balancing.
1. Display an all-white
image
Examples of all-white sources are a white PC Paint screen or frame
50823 on Reference Recordings, “A Video Standard” test disk.
2. Press the COLOR
button on the remote
control
Displays the Color Balance menu.
3. Maximize all settings
Adjust the white settings so that all are at 031 and all gray settings
are at 007.
4. Identify the least-
bright display in the
system
This display will serve as a baseline to which the other displays will
be adjusted since it cannot be adjusted to be brighter.
5. Luminance match
the displays
Beginning with the cubes adjacent to the baseline cube, adjust the
ALL settings on the white levels to approximately match the
luminance (brightness) of the least bright display.
6. Color balance the
displays – white
mode
Adjust the relative amounts of RED, GREEN, and BLUE in the white
(Wht) column to achieve the best match in color and luminance to
the baseline cube.
If a color appears to need to be increased, but that color is already
up as high as it can go, then the other two colors may be reduced.
7. Display a mid-level
gray image
Examples of mid-level gray sources are a 50% gray PC Paint
screen or frame 50824 on Reference Recordings, “A Video
Standard” test disk.
8. Color balance the
displays – 50% gray
mode
Adjust the relative amounts of RED, GREEN, and BLUE in the gray
(Gry) column to achieve the best match in color and luminance to
the baseline cube.
