Ok so I have this flat screen TV I want to connect to my notebook so I can watch movies on it instead of my small laptop screen. Thing is I can't get it to work.. I have a ATI mobility X700 on my laptop. I have bought a DVI cable which connects the TV and the comp. That's about it: my TV screen just stays blank on the DVI channel. I've been fideling around with the options to no avail. I think I bought the wrong cable maybe I should have bought an S-Video one? Because my PC has both a S-video and DVI connection. If it turns out I have to use S-video to connect to my TV what is the DVI connection used for? Any help is greatly appreciated!!
