Note: This control is currently not updating the chromaticity values in our input EDID
Output Chromaticity
Similarly, there are the Output Chromaticity controls which are required for accurate
calibration.
This control is typically not required since the Color Gamut control can correct for
incorrect chromaticity values provided by the display EDID. Users can think of this
control as a coarse color control, which may be useful when a meter is not available.
This new control is available in the Output Setup menu.
Main Menu > Output Setup > Chromaticity
By default the Chromaticity is set to ‘Auto’, which sets the chromaticity based on the
chromaticity information in the display’s EDID.
The chromaticity can also be manually set from this menu, which contains standard
profiles including RGBs/709, NTSC, PAL/SECAM, SMPTE-C, CIE1931, AppleRGB and
Adobe 1998.
When the Chromaticity is selected, the ‘hint’ area of the on-screen display shows
corresponding color and white point x, y values (red (xr, yr), blue (xb, yb), green (xg, yg)
and white (xw, yw)).
Color Gamut
The Color Gamut control allows adjustment of Red, Green, Blue primary colors and
white point on the CIE colorimetry chart. The Gamut adjustments are relative to the
selected output chromaticity.
This new control is available in the Output Setup menu.
Main Menu > Output Setup > Color Gamut
There are two ways to use this control.
a) Using the iScan Duo’s test pattern generator as a reference color source
b) Using an external video source to generate the reference test patterns
