Most types of data display devices work with a VGA signal. This includes most CRT monitors and data-grade projectors. Setting up a data display is pretty simple: Connect one end of a VGA cable to your computer's display monitor output, the other end to the display device. For the best-quality images, use the best cable you can find. A low-grade cable can dim the picture, distort its colors and cause sync problems, especially over long distances. (The VGA standard includes higher-resolution versions such as SVGA, XGA and so on. These use the same type of connector and cable.)
Tip: If your display device has a digital input, you may want to equip your computer with a display adapter that outputs this type of signal. This will allow the signal to stay in the digital domain, resulting in a better picture.
