There are two ways to hook two monitors up to your computer.

1. A dual monitor video card. These are very inexpensive - around $60. This is the best way to go since it will allow you to post the same image on both monitors or split the signal into two sections allowing your computer to work as a wide panorama.

2. A VGA splitter. This is simply a cable that will split your monitor signal onto two screens. This will only allow you to see the same image on both screens and it will likely present a lower quality image on both screens.
