• Diagnostic: Select Diagnostic from the Display Device - Configure menu, then select
Red, Green, Blue, Yellow, Cyan or Magenta to display only that color channel
(simulating a filter of that color). This can be useful for calibration or measurement
purposes.
To restore the normal picture (all colors), select White.
Color Space: Select Color Space from the Service menu to choose the color space of
the source signal for HDMI, RGB, and component connections.
• The default setting, Auto, functions as follows:
• HDMI: If the Auxiliary Video Information (AVI) infoframe contains color space and/or
range data, the DHD Controller uses that information. Otherwise, for RGB sources,
the DHD Controller uses the RGB-Video color space. For component SDTV and
EDTV resolutions, REC601 is used. For other component video resolutions,
REC709 is used.
• RGB: If Hsync or Vsync signals are present, the DHD Controller uses the RGB-PC
color space. Otherwise, REC601 is used for SDTV and EDTV sources, and REC709
for all other sources.
• Component: For SDTV and EDTV resolutions, the DHD Controller uses the
REC601 color space. For all other resolutions, REC709 is used.
In most cases, the Auto setting determines the correct color space to use. If it does not,
you can force the DHD Controller to use a specific color space. Choose one of the
following:
• REC709 sets the color space matrix to that defined in ITU-R BT.709.
• REC601 sets the color space matrix to that defined in ITU-R BT.601.
• RGB-PC uses RGB color space and sets black at 0,0,0 RGB and white at
255,255,255 RGB, assuming an 8-bit image.
• RGB-Video uses RGB color space and sets black at 16,16,16 RGB and white at
235,235,235, assuming an 8-bit image, to correspond to the luminance values defined
in digital component standards.
Color Gamut: Select Color Gamut from the Service 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 choose the SMPTE-C color gamut.
• Select EBU to choose the EBU color gamut.
Table 4-3 lists the Color Gamut settings and associated x- and y-coordinates for each
primary and secondary color component.
