What cord would I need to connect my dell laptop to my lcd high def TV. The plug on the TV for PC cable is there but the only ports on my laptop are usb ports and a somewhat squareish plug with lots of little prongs in it. When I went to the sound, computer and systems store the plugs to connect your TV to laptop had metal rings inside it but looked almost like the odd plug I have. Can anyone help me please

You have two options

s-video to VGA cable
VGA Male to VGA Male cable
