Figure 62: Diamond display plot
Set the thresholds for gamut. (See To set up gamut checks on page 202.) After
selecting the Diamond display, compare the signal to the display to determine
out-of-gamut components. Note the following:
■ The intensity of a vector indicates its duration.
■ A momentary out-of-gamut condition appears as a faint trace. Long duration
violations show as a bright trace.
When evaluating out-of-gamut components, consider the following examples.
(See the following image.)
■ Example A:
R - Ok
G > 700 mV
B - Ok
■ Example B:
R - Ok
G - Ok
B > 700 mV
■ Example C:
R - Ok
G - Ok, 350 mV
B < 0 mV
