Williams games are hard to put new monitors in. They have some weird
sync issue. I have only been able to use Electrohome GO-7 and Wells
4900 monitors. I just sold off a Robotron a week ago and I could not
get my new monitor to sync either. Good Luck
check to make sure both horizontal and vertical sync wires are in the
harness from the game, if not jumper whichever one you have to
whichever one your missing, on G07's you only need 1 sync, newer
monitors require both sometimes.
