input drives 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 external source. 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. Use Color Enable to select and display one primary color.
3. Adjust the current color's "Blacklevel" slidebar until a single band of black appears at one edge of the
screen. This band represents the first band of the grayscale pattern, which is 100% black. Do not adjust too
far.
4. With the same color still active, adjust the "Input Drive" slidebar 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 is 100%
white (or the current color, if a color is enabled). Do not adjust too far.
5. Check the black band and adjust the blacklevel slidebar if necessary. Blacklevel and Input Drive
adjustments are related, so you need fine tune them until both bands are optimized.
6. Repeat Steps 2-5 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.

Gamma Table
Use this option to apply a gamma table or "curve", controlling the intensity of midlevel colors while
maintaining maximum contrast, brightness and color performance. Select an appropriate gamma curve for the
incoming signal. Select "Simple" for most incoming signals, to apply a true 100% linear power curve. Select
"Graphics" to apply a simple power curve for graphics sources and "Video" to apply a curve with a linear
segment near black to compensate for increased blacklevels typical of video signals.
