For now, I'm just trying to get a picture, I can deal with the multi-display stuff later. the a/v input looks exactly like the earphone jack in case anyone still doesnt get it i have a cable for my canon powershot s30 that lets me plug it in to the camera's output (same jack as a/v on tv) and then there are two wires, one goes to vid, one to audio, i tried using this cable, but still no picture.
How are you sending the output from the vid card? I know on mine (8500) you have to go to the advanced properties and choose the TV as one of the monitor. I suggest you set a hotkey to switch to TV and back to normal...
