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
