Table 4-2 lists the x- and y-coordinates for each color temperature preset.
• 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.
• Auto automatically chooses the appropriate color gamut:
• SMPTE-C for NTSC, 480i and 480p sources.
• EBU for PAL, SECAM, 576i and 576p sources.
• REC709 for all other sources.
• REC709 chooses the REC709 color gamut.
• Select SMPTE-C to use the color gamut defined in SMPTE 170M-1999.
• Select EBU to use the color gamut defined in EBU Tech. 3213-E.
• Select Native for Runco's recommended Personal Color Equalizer preset for typical
video sources. It displays the fully saturated LED color gamut with appropriate color
brightness, hue, and Runco Smart Color settings.
• Select DCI to use the color gamut defined in Digital Cinema System Specification
Version 1.2.
• Select PCE to use the Personal Color Equalizer feature of the Q-750d. PCE lets you
define a custom color gamut. Refer to the next section, PCE, for instructions on how to
do this.
