levels, which ensure a specific color performance from
projector-to-projector, can be calibrated in the Service menu
only. The factory settings can be recovered with selection of
"Reset to Factory Defaults?" in the Color Primary Settings
submenu accessed via the Service menu (password-
protected).
From the factory, the projector can utilize any of the three pre-defined color performance settings identified at
right (default=Max Drives), or colors can be driven on the basis of color temperature. For most applications,
one of these gamuts will produce accurate and realistic colors from a variety of sources. They can be applied at
any time in the Advanced Image Settings menu ("Select Color Adjustment"), and are not adjustable.
DEFINING "USER" COLOR GAMUTS You may find the pre-defined "Select Color Adjustment" options
do not suit your needs. For example, you may require a unique color gamut (range) for a single projector or
application, or you may need to precisely match colors across multiple adjacent displays. In such cases, use the
Color Adjustments by X,Y or Color Saturation submenu to define the precise hue of each primary color
component (red, green, blue, and white) used to generate the millions of colors produced in displays. You can
create up to four custom color gamuts (User 1, 2, 3, or 4) with these adjustments.
The two menus differ only in their user interface, so use whichever menu best suits your needs and

application. A color meter can help with adjustments.
Use this submenu to create, alter or copy a color gamut (i.e., "color adjustment"). Controls in this menu define
the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of
colors produced in displays. The x/y coordinates for each color define its location on the standard CIE
chromaticity graph, see
either or both of these numbers will change the hue of the color, and relocate the "triangle" for possible colors.
For example, changing the x/y coordinates for red may move the color closer to orange or closer to violet,
which will in turn affect all displayed colors having a red component. Adjust the slide bars or enter new
specific coordinates as desired to define or change up to four "User" color gamuts needed for your
environment and applications. Apply at any time in the Advanced Image Settings menu.
