Two options are available in this field: Match Sample and Match Data.
In the Match Sample mode, white point calibrations are based on a measured reference display
– “Golden
Sample”.
Match Data mode allows the user to enter target values in terms of luminance (Y) and CIE 1931 x, y values.
Whichever method is chosen, all R G B measurements require that a Phosphor (either stored or custom) be
selected and that a reference white point is set.

Proper white point calibration is dependent on the color characteristics of the display primaries. Phosphor is
used as a historical reference to CRT’s. The data for several types of phosphors are pre-stored in the PR-7XX.
They are CIE, NTSC, EBU (PAL / SECAM), SMPTE and HDTV. The user may also enter display primary
chromaticity values or use measured values.
