Customize Entries in the VidChanX.ini Files

Each entry in the <VidChanX.ini> file indicates the voltage level, timing, and signal characteristics
of the video source. The values generated by Video Configuration Utility (VCS2) are based on
VESA and Industry Standards and are adequate in order to capture initial images.
If a video capture does not initiate, the most likely reason is that the VPOL1 field may be set
wrong. The Video Configuration Utility (VCS2), If provided with a channel number, will capture
and save a sample image to verify the proper state of the VPOL1 field. The image will be saved
to the filename <TestImage.bmp>. The image will be annotated with a calibration grid to verify
proper video alignment.
In certain rare cases it may be necessary to optimize the video to correct the colour balance.

Remarks
0 or 1. HSYNC Polarity
- Changing this value will increase margin at the left of the image
- Choose the value which produces the widest margin, and then
adjust with XDim1
0 or 1. VSYNC Polarity
Captured images will not be rectangular if incorrect value is chosen
-1=Internal, 0= Negative, or 1= Positive.
-1=Internal, 0= Negative, or 1= Positive.
