(described below).
6. Delete the "Auto" checkmark and leave the Input Levels menu.
IMPORTANT: Do not use Input Levels to adjust color temperature. This will
distort Contrast and Brightness functions as well as color temperature.

This option (full name sync tip clamping) can brighten the image
produced from certain high resolution, high frequency graphic sources. Enter a
checkmark if the image appears unusually dim, if there are horizontal streaks across the
image, or if there is significant color drift. Delete the checkmark if the image is either
sufficiently bright or overly bright. This option is useful for non-3D as well as 3D.
NOTE: The clamp tip option is not used for video sources or any RGB source with
sync information on the video (e.g., sync-on-green).

color saturation by applying the same gain for chroma levels (blue and red, i.e. "Pb,
Pr") as it does for luma levels (green, i.e. "Y")—this default processing is indicated
by a Chroma Input Gain value of "1000". With certain YPbPr signals, however, you
may need to improve the color saturation by applying a different gain (500-2000) for
chroma relative to luma—this new gain will modify how "Auto Input Level" sets the
red and blue drive values. Adjust the Chroma Input Gain slidebar under either of the
following conditions:
Y
If the ADP option is installed and you want to adjust color saturation
produced by your YPbPr signal (the
not function with ADP)
or
Y
If a certain type of YPbPr (analog) component video signal—typically
Betacam or M11 format—is producing incorrect color saturation.
Note that the Chroma Input Gain slidebar is not useful for other types of signals and
has no effect unless "Auto Input Level" is run (either through the checkbox or during
an Auto Setup), or unless there is no channel defined yet. When Chroma Input Gain
adjustments are done before a channel is defined, the new channel will be defined
with the chosen value rather than the default of "1000".

Select which color or colors you want to see, 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.
