G. The setting data of the CONTRAST, BRIGHTNESS, PIN-BALANCE, PARALLELOGRAM, ROTATION,
COLOR TEMPERATURE are common mode saved in the memory. Don't needed adjust it individual at every
timing Mode and save in the memory.
3. White Balance, Luminance adjustment:
A. Bias (Low Luminance) adjustment:
(a) Set mode 7 1024
x
768 Fh: 60KHz full white pattern.
(b) To make the adjustment condition is under the Factory preset window.
Same as step 2-C.
(c) Warm up more than 30 minutes.
(d) Brightness
set to maximum. Contrast
set to min. raster pattern, then adjust FBT screen VR to make
Y=1.0FL
±
0.2FL
(e) Set G-Bias
to make the setting value about 56, then adjust the R. B Bias individual to the color
temperature x= 283
±
10, y= 297
±
10.
(f) Readjust screen VR to y=1.0FL
±
0.2FL
B. Gain (High light) adjustment:
(a) Set mode 7 1024
x
768 Fh: 60KHz full white pattern.
(b) Brightness set to raster just cutoff and set the contrast to max.
(c) Adjust G-Gain
, B-Gain
, R-Gain
, to make color temperature x=283

±
4mm.
(c) Contrast set to max, Brightness set to cut off.
(d) Adjust VR401 to the luminance at 28 FL
±
1FL.
4. Focus Adjustment:
A. Set mode 7 1024
x
768 Fh: 60KHz with character full page.
B. Adjust brightness to center and contrast to max.
C. Then adjust focus VR1 to a fine vertical line.
D. Adjust focus VR2 to a fine horizontal line.
E. Repeat step C & D.to make the display focus performance very well.
