2.W/B ADJUSTMENT (100%): Change the input signal to 100% white level performance. Set the CHROMA7120 to
288 301 360 and MODE_RGB, then adjust the TV’s RG, GG, BG to make CHROMA7120 display to 100.
3.Press “ST” and save the adjustment. Then change the input signal to 26% white level performance. Set the
CHROMA7120 to MODE_RGB and CH3, check whether the color
temperature was in SPEC (color spec is
x ¡ 15;y ¡ 15;Y¡ 15)
In this time, most of the TV is in SPEC, while the others should be adjusted twice or more to make its color
temperature in SPEC.
4.CHECK CUT OFF: Change the input signal to 0% white leve l performance. Firstly, press the “brightness” from 80%
to 0% and make sure the Y is not changed. Secondly, change the input signal to 32 GRAYS performance and make sure
