8.3 Color temperature adjustment for PC
How to prepare
1. Set signal generator output signal to Full White.
2.Signal condition
VGA (75): 0.7Vp-p, Set up level: 0V
3.Input the signal into RGB (D-sub) terminal.
4.Set Picture setting up to reference.
How to adjust
1.Indicate service adjustment mode and adjust as follows by Remote Controller.
2.Measurement probe of CRT Color Analyzer CA-100 is set on the center of screen.
3.Adjust color temperature as follows by reducing one or two numbers of No.9, 10, 11.
( At least one of these datas should be 255.)
PC color temperature (COOL)
x=0.285± ± ± ± 0.005, y=0.294± ± ± ± 0.005, at 9300 K
4. Adjust color temperature as follows by reducing one or two numbers of No.12, 13, 14.
(At least one of these datas should be 255.)
PC color temperature (NORMAL)
x=0.300± ± ± ± 0.005, y=0.298± ± ± ± 0.005, at 7600 K
5.Adjust color temperature as follows by reducing one or two numbers of No.15, 16, 17.
(At least one of these datas should be 255.)
PC color temperature (WARM)
x=0.314± ± ± ± 0.005, y=0.327± ± ± ± 0.005, at 6500 K
