Use the
Advanced Image Settings
submenu to make the adjustments
necessary for lesser-used but more
specialized
applications
on
your
projector.
gaMMa Table
— This control applies a
default
video, graphics
or
simple
gamma
table or “curve” to your images, controlling
the intensity of mid-level colors and
producing maximum contrast, brightness
and color performance. As shown at right, the graphics curve
is a modified power curve that will show more detail in darker
areas of the projected content 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 true power
curve that does not alter the contrast or the intensity of mid-level
colors.
Keep in mind that any
Gamma Table
choice sets the related
Gamma
value (shown in the
Picture Adjustments
menu) to a 2.6
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.

— In “Select Color Adjustment”,
choose an overall color performance 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, which enables the nearby Color
Temperature slidebar and applies its current setting (default = 6500K).
If none of the pre-defined “Select Color Adjustment” options or color
temperatures suit 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 Temp Adjust
submenus, and is most often needed with
multiple-projector applications. Select the color adjustment producing the best color accuracy for
your application and installation.
To configure a “User” color adjustment (gamut), use either the
Color Adjustment by X/Y
or
Color
Temp Adjust
submenu found in the
Display Setup
menu under Geometry and Color.
noTes: 1) “Color Temperature” defaults to 6500K until changed. All four “User” options default
to SD Video unless the user has redefined them.
2)
Factory-defined color primaries, which
ensure consistent color gamut from projector-to-projector, can be calibrated in the Service
menu only. If you suspect alteration, the factory settings can be recovered with selection of
“Reset to Factory Defaults?” in the Color Primary Settings submenu within the Service menu
(password-protected).
