7.2 Setup A, manually increase Vg2 voltage until brightest
color reaches 100 scale
7.3 Setup A, adjust R/G/B cut-off (I C) for all colors at 100 +/-
7Scale
7.4 Setup B, adjust sub-contrast (I C) for RGB readings around
100, then adjust RGB gain for all colors at 100 +/- 2 scale.
7.5 Repeat 5.3.2, 5.3.3 (RGB cut-off and gain) to get both low and
high 9300 scales at 100(0.10FL+/- 0.05FL for low scaale;
for high scale. x/y tol/-0.005)
7.6 Setup C, adjust R/G/B cut-off (I C) for all colors at 100 +/-
7 scale
7.7 Setup D, adjust RGB gain for all colors at 100 +/- 2 scale.
7.8 Repeat 5.3.5, 5.3.6 (RGB cut-off and gain) to get both low and
high 6500 scales at 100 (0.10FL+/-0.05FL for low scale,
for high scale. x/y to/- 0.005)
7.9 Setup E, adjust R/G/B cut-off (I C) for all colors at 100 +/-
7 scale
7.10 Setup F, adjust RGB gain for all colors at 100 +/- 2 scale.
7.11 Repeat 5.3.8, 5.3.9 (RGB cut-off and gain) to get both low
and high 5500 scales at 100 (0.10FL+/-0.05FL for low scale,
for high scale. x/y tol/-0.005)
7.12 Setup G, Adjust ABL (I C) for 30FL+/- 0.5FL
7.13 Apply full white pattern, sRGB: sRGB cutoff and gain are
same as 6500 color temperature. Setting brightness at 50%,
then set sRGB contrast at 23 +/- 1 FL.

7. Alignment of Vg2 cut-off point, white tracking
Equipment : 1. Video Test Generator-801GC (Quantum Data)
2. Color-analyzer (Minolta CA-100)
Adjustment mode: 68.67KHz/85Hz with correctly adjusted
video size 355x265mm Use color-analyzer (Minolta CA-100) to
adjust cut-off and white balance.Before alignment, set initial
data as below (all values show on factory OSD):
Brightness=50%, Sub-Contrast=85%, ABL=70% (I C)
9300K
R cut-off =
%, R gain = 65% (I C)
G cut-off = % , G gain = 55% (I C)
B cut-off = %, B gain = 65% (I C)
6500K
R cut-off = % , R gain = 55% (I C)
G cut-off = %, G gain = 65% (I C)
B cut-off = % , B gain = 55% (I C)
5500K
R cut-off =
%, R gain = 55% (I C)
G cut-off = %, G gain = 55% (I C)
B cut-off = %, B gain = 55% (I C)
