Knowra VGA connector VGA connector A 15-pin, three-row connector that carries analog video signals between computers and displays. Its familiar blue shell became a common interface for computer monitors.
VGA pinout : The assignment of electrical signals to the fifteen pins of a VGA connector. Separate pins carry red, green, blue, synchronization, and display-identification signals.
Video Graphics Array : IBM’s 1987 graphics display standard for personal computers, including its video modes and signal interface. The connector takes its name from the VGA display standard it was designed to serve.
Computer monitor : An electronic display designed to show visual output from a computer. Connecting a computer monitor was the VGA connector’s central use.
DVI : A video interface standard that carries digital signals and, in some versions, analog video. DVI can preserve digital video from source to display instead of relying on VGA’s analog path.
Analog RGB : A video representation that encodes an image as separate analog red, green, and blue signals. VGA sends the image’s color channels as three continuously varying voltages.
IBM PS/2 : A family of IBM personal computers introduced in 1987. IBM introduced VGA and its connector with the PS/2 computer line.
Video projector : An optical device that projects an image onto a screen or other surface. VGA became a common way to send computer images to presentation projectors.
HDMI : A digital interface that carries video and audio between audiovisual devices. HDMI combines digital video and audio, unlike VGA’s analog video-only connection.
Horizontal synchronization : A timing signal that marks the start of each displayed line in a video signal. A VGA display uses horizontal timing pulses to position each line of the image.
DE-15 : A 15-contact D-subminiature connector format with two rows of contacts. The VGA plug uses the smaller, three-row DE-15 form, often mistakenly called DB-15.
