A display standard for personal computers.
VGA was originally a graphics standard developed by IBM that allowed for 640x480 resolution with 16 colors. This standard has obviously been advanced to provide the greater resolutions and colors we enjoy today, but all computers support at least VGA mode. The term VGA is now mainly used to describe the 15-pin analog connection found on many graphics cards for connecting a monitor. The blue connection seen on the right-hand side of this graphics card's back plate is a VGA connection.
This acronym is short for the "Video Graphics Array" display mode. VGA resolution is 640 x 480 pixels.
