Why doesn't my HDMI connection work? I've connected my VGN-NW20 with a LG HDTV via HDMI cable from a HDMI port in my laptop. But when I try to access it on the tv, it says 'no signal'. I haven't tried VGA because a) it's inferior quality, and b) I dont have a cable. I want to make sure that I havn't done anything wrong before I purchase one.
