Check your video card. Pretty much every X800xl model come with S-Video or composite cable adapter, or both, that will plug into the back of your video card and allow you to hook up a TV as a monitor.
Be advised, your desktop outputed to a standard, non-HD television will look like crap compared to a regular monitor.
