COLOR ENABLE – Select which color or colors you want to see in the display, useful while working with color
temperature white levels or input levels. NOTES: 1) Input levels apply for the current source only, but for any color
temperature used. 2) Assuming that color temperature has been set up based on the internal test patterns, you
can then set up input levels for a given source so that it matches the color temperature of the internal test
patterns.
PEAK DETECTOR – The Peak Detector is a tool to assist with defining individual input levels, enabling you to
accurately set the Input Levels for any particular source with the appropriate image. Enabling the Peak Detector
activates a special operating mode for detecting only pixels that are considered black or white — all other levels
are displayed as a mid‐level gray. When used with a smooth grayscale pattern in which black and white are known
to be at opposite edges of the image, you can watch these isolated areas while adjusting individual black levels and
white levels until both black and white edges are just visible and distinguished from neighboring pixels. Images
from this source will then display correct blacks and whites without crushing.
Adjusting Input Levels Using the Peak Detector:
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.
2. Display one primary color. NOTE: Selecting Auto Color Enable insures 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 "White Level" 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. 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.
