•ConstantContrast: Select ConstantContrast from the Display Color menu to enable (Low/Medium/High) or disable (Off) ConstantContrast in the optical engine. ConstantContrast uses a dynamic iris that modulates light to the DMD based on the actual content of the video material. Runco recommends that you disable ConstantContrast before adjusting Brightness, Contrast or other image settings.

•Color Gamut: Select Color Gamut from the Display Color menu to select a color gamut (range) that may be different from the default color gamut.

Each setting defines the precise hue of each primary (red, green and blue) and secondary (yellow, cyan and magenta) color component used to generate the millions of colors produced in displays. Changing this setting relocates the “triangle” for possible colors (see Figure 4-7). For example, changing the x/y coordinates for red moves the color closer to either orange or violet, which in turn affects all displayed colors having a red component.

Note	The DHD Controller uses the Color Gamut settings for all display
	modes on a given input.

•Auto automatically chooses the appropriate color gamut:

•SMPTE-Cfor NTSC, 480i and 480p sources.
