material will look best with the video setting while some video material is best with
the graphic setting.
SELECT COLOR ADJUSTMENT: In “Select Color 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 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 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 they have been redefined by the user. 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 — Adjust to apply a specific and accurate 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.
RESERVED — No function.
WHITE BOOST — White boost is a source dependent setting that enables you to
recapture some of the lost light from the transition between segments in the color
wheel as it’s spinning. For NTSC, HDTV, PAL and SECAM signals the white boost
defaults to “2” and for graphic signals or when a test pattern is selected it’s “10”.
When white boost is set to zero, it is off and the option grays out in the menu. As you
increase the value of white boost you will notice that the image becomes increasingly
brighter and a little less saturated.
NOTES: 1) White Boost is automatically disabled (grayed out in menu) when you
enable Brightness Uniformity, Edge Blending or select a color adjustment (Select
Color Adjustment) other than “Max Drives”. The grayed out value you see is the last
value loaded before being disabled. 2) White Boost can also be adjusted specifically
