5. It may be advantageous to go back and check the black band—adjust the
blacklevel slidebar if necessary. NOTE: Readjusting blacklevels at this point
affects the gain; 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.

GAMMA TABLE:
applies a default video or
graphics gamma table or "curve" to your
images, controlling the intensity of midlevel
colors and producing maximum contrast,
brightness and color performance. As
shown at right, the graphics curve is a
simple power curve while the video curve
has a linear segment near black to compensate for increased blacklevels typical of
video signals. Although the projector automatically applies either the graphics or
video curve according to what type of incoming signal is detected, in some cases you
may wish to override this default and use graphics gamma for a video source or video
gamma for a graphics source. Alternatively, if neither default is ideal, you may prefer
to apply a user-defined custom gamma curve that has been created externally, named,
and downloaded to the projector (requires separate PC-based Arbitrary Gamma and
KoRE Librarian software applications). If any of these special user curves have been
installed, their names will appear in the Gamma Table pull-down list.
