9300K alignment:
2.1 Input 1600x1200 / 60Hz & full white pattern at 100IRE.
2.2 Adjust R, G, and B Gain to meet following chromaticity spec:
9300K → x = 0.283 ± 0.005, y = 0.298 ± 0.005, Y > 150cd/m 2 (Both analog & DVI).
6500K alignment:
3.1 Input 1600x1200 / 60Hz & full white pattern at 100IRE.
3.2 Adjust R, G and B Gain to meet following chromaticity spec:
6500°K → x = 0.313 ±0.005, y = 0.329 ± 0.005, Y > 200cd/m 2 (Both analog & DVI).
5400K alignment:
4.1 Input 1600x1200 / 60Hz & full white pattern at 100IRE.
4.2 Adjust R, G, and B Gain to meet following chromaticity spec:
5400K → x = 0.335 ± 0.005, y = 0.350 ± 0.005, Y > 180cd/m 2 (Both analog & DVI).
5000K alignment:
5.1 Input 1600x1200 / 60Hz & full white pattern at 100IRE.
5.2 Adjust R, G and B Gain to meet following chromaticity spec:
5000°K → x = 0.346 ±0.005, y = 0.359 ± 0.005, Y > 180cd/m 2 (Both analog & DVI).
sRGB alignment:
6.1 Input 1600x1200 / 60Hz & full white pattern at 100IRE.
6.2 Adjust R, G and B Gain to meet following chromaticity spec:
sRGB → x = 0.313 ±0.005, y = 0.329 ± 0.005, Y > 200cd/m 2 (Both analog & DVI).
64 grays and 16 grays pattern check:
7.1 Input a 1600x1200 / 60Hz, 64 gray-level pattern at 100IRE, with brightness set to 100% and
contrast set to 70%
7.2 Verify that under the 9300K / 6500K / 5400K / 5000K settings, no more than 2 of the 64
grays are saturated.
7.3 Input a 1600x1200 / 60Hz, 16 gray-level pattern at 100IRE, with brightness set to 100% and
contrast set to 100%.
7.4 Verify that under the 9300K / 6500K / 5400K / 5000K settings, no more than 4 of the 16 grays are
saturated.
