How do you connect HD tv to a computer?

Some high-end HD TV's come with VGA connections. For these TV's, simply purchase a VGA cable. For those TV's without VGA, you can either buy an HD compatible video card to put into your computer, or a low-end video card with S-Video outputs. The S-Video option will give lower quality, but the cost is cheaper than the HD card.

Depending on your computer, you may have an HDMI connector. Most HD TV's have one HDMI connector or more, in which case you can buy a male to male HDMI cable of the appropriate length, and connect the TV to the computer. Don't forget to program the input of the TV to use the HDMI port.
