My new cable just came in so I attempted to plug my monitor into my DVD player. The cable is male composite - male VGA and the monitor has a VGA input. It was desiged as a computer monitor, but it's an 18" LCD so I figure it should work alright as a secondary screen to watch DVD's on. The problem is I get no picture at all when the VGA to composite cord is plugged in correctly. Any ideas why? I can't figure this thing out.
