2.3 Allowed85Hzoverscansignalmodespecified
Once the signal input of PC is 85Hz, this monitor is able to display
at least for 10 minutes. An attention signal appears and shows "This
is 85Hz overscan, change computer display input to 1280X1024@
60 Hz "

3. Power Supply
3.1 Set up the AC I/P at 90VAC, add (B)
2.7A loading to +12V O/P and DC O/P voltage is 12V +/- 1.2V,
2.1A loading to 5V O/P and DC O/P voltage is 5V +/- 0.25V
3.2 Check voltage at (B)
5V O/P should be within the range 5V +/- 0.25V
12V O/P should be within the range 12V +/- 1.2V
4. Display Adjustment
4.1 Access to factory mode (RS232) in auto-alignment system
The communication protocol switches to RS232.
4.2 Auto color adjustment (B)
Apply a 640*480/60Hz signal with 16 level grey test pattern, set
brightness control at 100%, and contrast control at 50%. Adjust
the R.G. B. offset, and gain to calibrate the color smoothly and
64-grey level distinguishable.
4.3 Adjustment of WHITE-D (B)
Apply a 1280*1024 / 60Hz signal with white pattern, set
brightness control at 100%, and contrast control at 50%. Adjust
the R, G, B Sub-Gain, for the screen center, the 1931 CIE
chromaticity (X, Y) co-ordinates shall be
9300°K 6500°K
x (center) 0.283 ± 0.020 0.313 ± 0.020
y (center) 0.297 ± 0.020 0.329 ± 0.020
Use Minolta CA-210 for color coordinates and luminance check.
Luminance is > 200 Nits in the center of the screen when brightness at
100% and contrast set to 100%.
4.4 Adjustment of sRGB (B)
Apply a 1280*1024/ 60Hz signal with white pattern, set brightness
control at 100%, and contrast control at 50%. Adjust the R, G, B
Sub-Gain, for the screen center, the 1931 CIE chromaticity (X, Y)
co-ordinates shall be;
sRGB
x(center) 0.313 ± 0.008
y(center) 0.329 ± 0.008
Ynits 180 ± 10
4.5 EEPROM presetting (B)
After finishing all the adjustment, set:
Brightness control to 100%
Contrast control to 50%
OSD position at middle of screen
COLOR adjusts to 6500K color.
VOLUME control to 60%
