Just to add somthing, if your tv is a newish model - you will need need a DVI to HDMI cable. This will give you the best quality of picture.
If your tv hasnt a dvi connection, I am sure it has a VGA (blue) connector. All you need then is a male to male VGA cable.
Purchase these from ebay, if you can. I bought a TV from Harvey Norman last weekend, and they were selling HDMI cables for €99. I got one of ebay for €6. No difference...
