7-5. Contrast Tracking Adjustment Signal: No.23 (1600*1200@85Hz) Window Pattern (H: 33% V:33%)
1) Receive Signal 23.
2) Open Menu (S), TAG8 "CONT MAX/MIN". Adjust "+" SW so that the contrast is max.
3) Setting modes x, y, Y at the color analyzer, measures the window color temperature. This measurement
determines x=x1, y=y1.
4) Open Menu (S), TAG8 "CONT MAX/MIN". Adjust "-" SW so that the contrast is min.
5) Measure the window color temperature. This measurement determines x=x2, y=y2.
6) Open Menu(S), TAG8 "G BIAS", "R BIAS", "B BIAS" and make sure that the window color temperature are
the following values :
x2 = x1 ± 0.003
7) Open Menu (S), TAG8 "CONT MAX/MIN". Adjust "+" SW so that the contrast is max.
8) Measure the window color and confirm that the readings are the following values :
x1 = x2 ± 0.003
If not, repeat items 3) to 8).
9) Push "EXIT" SW twice.
7-6. Brightness Tracking Adjustment
1) Receive Signal 23.
2) Set modes x, y, Y at color analyzer.
3) Open Menu (S), TAG9 "G SUB BRIGHT", "B SUB BRIGHT", "R SUB BRIGHT" and push "RESET" SW.
(Each figure becomes 0.)
4) Adjust "+", "-" SW so that the "G SUB BRIGHT" is 5 ± 0.5 cd/m
5) Adjust "R SUB BRIGHT", "B SUB BRIGHT" and adjust "+", "-" SW so that the each color temperature
measured in step 7-5.
x = x1 ± 0.002
y = y1 ± 0.002
6) Push "EXIT" SW.
7-7. Color Preset Adjustment
1) Receive Signal 23.
2) Open Menu (S), TAG A and push "RESET" SW. (R/G/B COLOR GAIN value is made the early stages.)
3) Open Menu (S), TAG A, "Color Preset No.1 9300k ".
4) Open Menu (S), TAG A, and adjust "R COLOR GAIN", "G COLOR GAIN", "B COLOR GAIN" so that the
color temperature is the following value. (RGB either value make become 255 at this time.)
x = 0.283 ± 0.003
y = 0.297 ± 0.003
5) Push "EXIT" SW.
6) Open Menu(S), TAG A, and adjust Color Presets No.2 to 5 (8200K ~ 5000K) to the following values :
COLOR PRESET No.
2(8200K)
3(7500K)
4(6500K)
5(5000K)
y2 = y1 ± 0.003
y1 = y2 ± 0.003.
