Appendix IV – Auto Color Gain
The Auto Color Gain function is supported in the ARGB or Component video mode only and
is designed to calibrate the controller to the incoming video signal. In order to calibrate correctly, the
display must be displaying an image containing both black and white data (see illustration below)
when the function is used. The internal processor of the video controller chip will then execute a
process to adjust the relative values of the RGB signals to achieve the best performance. The
parameters of the corrected RGB values are then stored in the controller and are unaffected by the
Reset Factory Defaults function.
The reference pattern can be downloaded at :
http://www.digitalview.com/support/downloads/TestPattern_1280.BMP
This reference pattern is for 1280x1024 resolution and it needs to set your ARGB input source to
1280x1024 resolution before performing the Auto Color Gain function. The position of the black
vertical bar in the pattern at the right side is important. It will affect the calibration result if you are
setting the ARGB input to other resolution.
Warning - If the Auto Color Gain is executed without an appropriate image being displayed, then the
process will set incorrect values and the display colors will be distorted. If this occurs, then it can
either be corrected by performing the process correctly or if this is not possible then the Reset Color
Gain function can be used. This function will reset the stored RGB values to a set of approximate
values.
