submenu to make the adjustments
necessary for lesser-used but more
specialized applications on your
projector.
NOTE: 3D Source option is
available for Mirage HD.
This control
GAMMA TABLE:
applies a default video, graphics or
simple 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 black levels typical of video
signals. A simple gamma curve is a value of 2.2 and is correct for most signal
conditions. 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
the simple (non-optimized) gamma curve or 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.
Keep in mind that any Gamma Table choice sets the related Gamma value (shown in
the Image Settings menu) to a 2.2 default, where it can be fine-tuned as desired.
Different values (1-3) here indicate that the original gamma table has been adjusted
with either the Gamma slide bar or direct key.
SELECT COLOR ADJUSTMENT:
Adjustment", choose an overall color palette for all images.
The "Max Drives" factory default simply drives all 3 colors
at their maximum level so that they are fully on and cannot
be changed. The two other pre-defined color adjustment
choices—SD Video and HD Video—apply a color gamut
optimized for video sources (standard or high-definition).
Alternatively, you can specify a color temperature. This
enables the adjacent Color Temperature slidebar and applies
its current setting (default = 6500K). If none of the pre-defined "Select Color
Adjustment" options or color temperatures suits your application, select one of four
color gamuts previously defined by a user (User 1, 2, 3, 4). A "User" option applies a
customized color performance in which the user has precisely set the hue and
intensity of each color component in the Color Adjustment by X/Y or Color
