6-3-1 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.
CONDITIONS
Measurement instrument: Color analyzer
Scanning frequency: 53.6 kHz/85Hz
Display image: White flat field at
center of display area
Luminance: Maximum
PROCEDURE
Use the directions in sections 6-3-2 through 6-3-3
to adjust the color coordinates for:
9300K to x = 0.283 ± 0.02, y = 0.298 ± 0.02
6500K to x = 0.313 ± 0.02, y = 0.329 ± 0.02
6-3-2 Color Adjustments for 9300K
6-3-2 (a) BACK RASTER COLOR ADJUSTMENT
CONDITIONS
Scanning frequency: 53.6 kHz/85Hz
Display image: Back raster pattern
Brightness: Maximum
Contrast: Maximum
1. Select COLOR CHANNEL 1 to control the
color for 9300K.
2. Adjust the luminance of the back raster to
between 0.5 to 0.7 ft-L using the G_CUT
controls.
3. Click on the << or >> box next to B_CUT to
set the “y” coordinate to 0.298 ± 0.02.
4. Click on the << or >> box next to R_CUT to
set the “x” coordinate to 0.283 ± 0.02.
Note: If the above adjustments cannot be
done to each coordinate, click on the
<< or >> box next to G_CUT to decrease
or increase the green cutoff (bias) and
repeat procedures 3 and 4.

1. Click on the << or >> box next to G_GAIN to
adjust the brightness of the Green Gain to
40 ± 1 ft-L.
Note: If you can’t increase the Green Gain to
the appropriate value, click on the >>
box next to increase the ABL point.
