Texas Instruments DW30, MATRIX 3000 user manual

Section 3: Operation

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 for internal test patterns. However, once you switch back to a source, the White Boost settings will reset to the value set for that source. 3) If the ChristieTWIST module is installed and edge blending is enabled, White Boost is still active and can be adjusted to suit.
