1.
Display a 16 level grayscale test pattern from the desired external source, and
enter a checkmark in the Peak Detector checkbox.
NOTE:
The “Peak Detector” will initially render the grayscale as a uniform gray
field before adjustment or extreme crushing.
2.
Display one primary color.
NOTE:
Selecting Auto Color Enable ensures the correct color is displayed for
each setting.
3.
For the current color, adjust its corresponding “Black level” slide bar
just
until a
single band of black appears at one edge of the screen. This band represents the
first band of the grayscale pattern, which should be 100% black. Do not adjust too
far.
4.
With the same color still active, adjust its corresponding “Input Drive” slide bar
just
until a single band of color appears at the opposite edge of the screen. This
band represents the last band of the grayscale pattern, which should be 100%
white (or the current color, if a certain color is enabled). Do not adjust too far.
5.
It may be advantageous to go back and check the black band—adjust the black
level slide bar if necessary.
NOTE:
Readjusting the black levels affects the gain at this point; only readjust
when absolutely necessary.
6.
Repeat Steps 3-5 with the other two remaining primary colors. When each
primary color shows
one
optimized black band and white (or colored) band, the
input levels for this source are correctly set. Upon exiting the
Input Levels
menu,
the Peak Detector checkbox will clear.
