How do I connect my laptop to my TV to watch a movie?

I have a movie on my Dell C 600 that I would like to play on my Television. I have a TV out socket on my laptop but when I connect the TV to my laptop nothing happens? What do I need to make it work? Do I need a TV card? Do I need software?

I have a Dell and have used a HDMI lead and it works fine but I am not sure if your supposed to do it this way have not found any info but it does work, i understand you must not connect the HDMI lead while tv or laptop are switched on and switch off before disconnecting.
