I successfully did it. I connect as instructed on the paper, I connect the black wire to the gold screw, brass wire to the silver screw. But there is no ground wire (green) or anything like that. Only two wires. I only connect two and I just tested by turning the computer on and the monitor. So far, nothing really bad happen to the monitor yet.
So, it\'s a bad thing if there is no ground wire to connect to the green screw?
