ok, this seems stupid, but try each monitor one at a time. If they both work individually awesome, if not well sucks for you.
I’m going to assume you’re on XP
1.) Drivers…update them
2.)you should really be doing this through ATI’s catalyst control center, trust me its easier. Open that bitch up and start messing with things, without better info that’s all I can suggest.
3.) For the TV you will probably have to switch to it from the Catalyst Control Center, by default the RCA’s are not on.
Try it out, report back.
