Checking Gamut
To isolate gamut bright-ups, try the following:
Use the LINE SEL button to select individual lines
Use the PICT display to examine the signal (turn on gamut bright-ups in the Display Settings submenu of the
Configuration
menu)
Use the Arrowh
ead % setting (found in the Gamut Thresholds submenu of the C on figuration menu) to specify a
percentage of the screen to ignore for gamut violations.
Checking Composite Gamut
The Arrowhead gamut display plots luminance (Y) against chrominance (C) to check if the composite signal adheres to
standard gamut. NTSC and PAL Arrowhead displays (75% Color bars) and indicates the values of the graticule lines.
The arrowhead shape of the graticule results from overlaying the standard limits for luminance and luminance-plus-peak
chrominance.
