Color Gamut: Select Color Gamut from the Advanced 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 either or both of these numbers changes the hue of the
color and relocates the “triangle” for possible colors. 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-650i. PCE lets you
define a custom color gamut. Refer to
PCE on page 60 for instructions on how to do
this.
