Help! I'm trying to connect my Sony Vaio laptop to my LG LED television using VGA cable. There is a place on the side of my laptop that will accomodate the 15 prong VGA cable as well as in the back of the television, there is also a 15 prong outlet that would accept the VGA cable, and it is labled RGB (IN) PC and when both ports are connected via VGA casble, I do not get the computer screen to show on my television monitor. I've changed the source, but I do not have VGA listed as one of the television sources, but I do have RGB PC and when I click on that option, I get an "Invalid Format" signal on the televison screen. Can someone out there please help me through this torment????!!!!! Thanks!
