A VGA connector (Video Graphics Array) is a type of interface used to connect a computer to a monitor or display. It transmits analog video signals and typically features a 15-pin D-subminiature connector. VGA was widely used in the 1980s and 1990s, making it a standard for video output in many computers and projectors. Despite its popularity, VGA has largely been replaced by digital interfaces like HDMI and DisplayPort, which offer better video quality and support for higher resolutions. However, VGA is still found in some older devices and is useful for connecting legacy equipment.
