Different Types of Computer Monitor Connections

By Gregory Thompson

Monitors have different types of connections to hook it to a computer. Some connections are analog, while new technology lets a user attach a monitor digitally to get the best possible picture available as output.

VGA

The Video Graphics Array analog connection has been around since 1987, and it can be recognized by the 15-pin configuration. Most VGA ports on the computer are blue.

S-Video

One different type of connection for a monitor that gives better picture quality than VGA is S-Video. This is a 5-pin setup that typically has yellow or black ports.

DV-I

Since the mid-2000's, the Digital Video Interface connection has become a common port on computers and monitors. There are 24 pins on this connection, and the port is usually white or off-white.

HDMI

For a true digital connection with precise color, definition and sound, use an HDMI cable. This is a port that resembles a USB port, but it is slightly tapered.

Considerations

To ensure a user receives the best possible picture, connect the monitor to the computer using the same ports; that way, no conversion---which could degrade the video signal---is needed.
