8.4 Preliminary Calibration
All primary colors in the projector are precisely set to pre-established values to ensure that overall color
performance is optimized and is as accurate as possible. Lighting and other environmental factors may slightly
change how these colors appear on your screen. While the change is negligible in most cases, you may prefer to
recover the originally intended color performance before trying to match colors.
To achieve consistency use a color meter to measure the native primary colors—red, green, blue, and white—as
they appear at the screen. Record these as Color Primary Settings in the Service menu (password-protected) for
this unit. On the basis of these new values, which are stored in memory, each projector will then automatically
calculate any necessary corrections to reproduce the original factory colors under the current environmental
conditions. This essentially calibrates a projector to its surroundings, compensating for factors such as screen type;
lamp and/or ambient lighting and will improve color accuracy and consistency in a group of projectors. It ensures a
good starting point for further customizing and matching; however, is not critical for all installations.
To access the Service menu (password-protected) return to the factory-set color primaries. Select the “Reset to
Factory Defaults?” option in the Color Primaries submenu. Then repeat the calibration process describe above and
continue with matching of colors.
8.5 Color Adjustment Procedure
Once the Color Primary Settings are calibrated for the site, use the Color Adjustments by X,Y or Color Saturation
menu to further refine each projector’s fundamental colors so that the hue and intensity of each color to match the
desired Test pattern colors.
Color Adjustment by X/Y
Enter known x/y coordinates from the chromaticity graph
NOTES:
1) For defining or changing a User 1, 2, 3, or 4 color performance or “gamut”. Sometimes known as Comprehensive
Color Adjustment™.
2) Factory-defined primary color 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.
NOTE: 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 Figure 3-38 CIE 1931 Chromaticity Diagram (without Yellow Notch Filter). Changing 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.
