Many newer TV's have VGA inputs to connect your computer to your TV. All laptops and desktops have these outputs. Some TV's have a DVI input, which are mostly video card outputs. Video cards also support S-video outputs, which is another input in most TV's. If you have an HDTV, you can either get a high level video card with an HDMI output, or you can get a DVI-HDMI converter. Depending on the size of the TV, you may need a new video card.
