One of my G4's I am able to connect to a TV with a VGA cable. But my other G4 doesn't use the same cable. The port instead has 3 rows of holes (for pins) and then beside that, a plus sign with a hole in each quarter. What kind of cable is needed to connect this G4 to a TV, please? It's an HDTV. It's a 1Ghz PowerBook G4 15" with OS 10.4.11. It doesn't have Bluetooth. Thanks
