requirements:
Input Signal Type: PC signalAt factory mode apply 1024X768 /
60Hz with TVBAR100 pattern and set Brightness and contrast
to be 50%.Activate AUTO-COLOR function for auto ADC offset
and gain setup.
Figure 8-2 TVBAR100
Colour Temp Alignment Apply a 1024*768 / 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
centre, the 1931 CIE chromaticity (x, y) co-ordinates shall be:

If you have not CA-210, the following R,G and B values are for
your reference.

Luminance > 400 cd/m2 in the centre of the screen when both
contrast and brightness are 100%. This group setting about
colour temperature is also applied in HDMI 1/HDMI 2/CVI 1/
CVI 2/AV/Side AV/PC. It means that all these inputs use the
same setting.Display quality adjustmentUse timing mode as
described in 2.2, and uses the POPO (Pixel On Pixel Off)
pattern to adjust the clock until no stripe and adjust the phase
until clear picture. (AUTO ADJUST hot key: press VOLUME n
and VOLUME + keys together for 1 second). Check all six
