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.
