What does the TV have for connection. VGA, HDMI, or S-Video.
If the TV has a VGA just connect to that just like to a computer monitor. But you will not have sound to TV only Video.
If the TV has a HDMI connection you have to buy video card with HDMI port. Than you will have sound and video.
If the TV has S-Video connection you have to buy a Video card with a S-Video port. You might not have sound.
You can connect it by a DVI to HDMI cable but you will not have sound to TV only Video. That is if the TV has HDMI.
