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 —
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 slide bar 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

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.
