What is a VGA connector?

A VGA (Video Graphics Array) connector is a 15-pin D-sub connector used to transmit analog video signals from a computer to a display device, such as a monitor or projector. Introduced in 1987, it became a standard for video output in PCs for many years. VGA supports resolutions up to 640x480 pixels but can handle higher resolutions with reduced quality. While it has largely been replaced by digital interfaces like HDMI and DisplayPort, VGA is still found in some older devices and legacy systems.
