this circuit
separate sync signals from composite video,it may help you with some 
level adjustement,to apply your composite video to vga screens
maybe you can find commercial products on ebay but it will be more 
expensive ....
best regards

This card has a monochrome composite output (resolution is as low as about 512x400, but I might replace it with a higher resolution card). A small 9" HP monitor that I used for testing only shows me 2 or 3 bands of the image and cannot capture the signal properly.
