I have an HDTV that displays up to 1080p. I have the the 1st Gen xbox 360. I was wonderning If I bought the VGA Cables and Plugged it in my TV because it has the option to serve as a Monitor would I be playing in HD and Also would I be able to hear out the TV because It offers the L and R output so I wouldnt have to use speakers ! If anyone can tell me Im confused !! or should I just buy HD cables??
