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.
It may be advantageous to go back and check the black band—adjust the
5)
blacklevel slidebar if necessary. NOTE: Readjusting blacklevels at this point
affects the gain; only re-adjust if absolutely necessary. Adjust until both bands
are just optimized.
Repeat Steps 2-5 with the other two remaining primary colors. When each
6)
primary color shows one optimized black band and white (or colored) band, the

This control applies a default video or graphics gamma table or
GAMMA TABLE:
"curve" to your images, controlling the intensity of midlevel colors while
maintaining 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 graphic 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
