What is a vga socket 15 pin?

A VGA (Video Graphics Array) socket is a 15-pin connector used primarily for video output from computers to displays, such as monitors and projectors. It transmits analog video signals and supports resolutions up to 640x480 pixels, though higher resolutions can be achieved with lower refresh rates. The connector is typically blue and has three rows of five pins, with pins responsible for transmitting the red, green, and blue color channels, along with horizontal and vertical sync signals. Though largely replaced by digital interfaces like HDMI and DisplayPort, VGA is still found on some legacy devices.
