4-3-1 Color Coordinates (Temperature)
Color temperature is a measurement of the radiant energy transmitted by a color. For computer monitors, the color temperature refers to the radiant energy transmitted by white. Color coordinates are the X and Y coordinates on the chromaticity diagram of wavelengths for the visible spectrum.

1.Select Ò@1: CHANNEL 1Ó in right menu to control the color for 9300K.
2.Adjust the luminance of the back raster to between 0.5 to 0.7
3.Use control bar after selecting ÒBLUE CUTOFFÓ in left menu to set the ÒyÓ coordinate to 0.298 ± 0.02.
4.Use control bar after selecting ÒRED CUTOFFÓ in left menu to 0.283 ± 0.02.
*If color values would not be matched desirable values, repeat sequence 3 and 4 after readjusting ÒGREEN CUTOFFÓ control a little different.
