2.4.5 Adjusting the cut off
(1) Input the timing No. 12 (106.25kHz/85Hz, 1600x1200) (R, G, B OFF).
(2) Set BRIGHTNESS to 127, SUB-BRIGHT to 380, and the R, G, B-BIAS of COLOR1 (9300)
in FACT 3 to 30.
(3) Adjust the back raster luminance to 0.3
±
0.1cd/m 2 with SUB-BRIGHT.
When the back raster luminance is less than 0.3cd/m 2 even after SUB-BRIGHT was
changed, change R, G, B-BIAS 9300 to adjust.
The R, G, B-BIAS 9300 data must be the same at this time.
(4) Using two colors except for the basic colors, adjust the color coordination to the following
values.
(5) Change SUB-BRIGHT, and adjust the back raster luminance to 0.3
±
0.1cd/m 2 .
(6) If the back raster color coordination is deviated from the following values, repeat steps (4)
and (5).
(7) Set the G-BIAS datas of COLOR sRGB (6500) and 5 (5000) to the same value as the one
of COLOR1 (9300).
(8) Select COLOR sRGB (6500), and change the BIAS data for the R and B colors (G-BIAS is
fixed). Adjust the back raster color coordination to the following table.
(9) Select COLOR 5 (5000), and change the BIAS data for the R and B colors (G-BIAS is
fixed). Adjust the back raster color coordination to the following table.
NOTE) Adjustment of COLOR 2 and COLOR 3 is no need.
