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
Saturation submenus. It 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 Saturation submenu.
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).
COLOR TEMPERATURE —
to all displays. Color temperatures are expressed in degrees Kelvin (3200-9300K),
and utilize different combinations of the projector's original native color primaries to
produce a "coloration" or cast (reddish or bluish) in images—the lower the
temperature, the more reddish the cast; the higher the temperature, the more bluish
the cast. Note that the slidebar is enabled only if you have a source connected and
have selected "Color Temperature" in the adjacent "Select Color Adjustment" pull-
down list in the Advanced Image Settings menu.
The optical aperture inside the projector controls the diameter

OPTICAL APERTURE -

of the light beam passing through the system. With a fully open aperture (slide bar
default of "0"), the maximum amount of light passes through for maximum
brightness in your images. Increase the slide bar setting to reduce the aperture
diameter and maximize contrast ratio instead. Performance of aperture depends on
the lens in use. NOTE: Optical Aperture also appears in the lamp menu.

APERTURE MANUAL ADJUSTMENT

on the 1.2:1 and 1.1:1 lens. It may be used together with the internal electronic
aperture to increase the contrast ratio; noting a slight decrease in brightness when it is
used. It is recommended for highest brightness operation, under normal conditions,
the manual aperture is to be left open. See Aperture Manual Adjustment below for
aperture open/close and lock and unlock dial positions. NOTE: The lock/unlock dial
position allows you to open the aperture at a desired position and lock it in place.
