What is VGA?
VGA (Video Graphics Array) is an analog video connection standard that was introduced in 1987 and has since become one of the most widely used methods for connecting computers to monitors and projectors. VGA transmits video signals in analog format, supporting resolutions up to 640x480 pixels, though higher resolutions can be achieved with certain devices and setups. Despite being largely replaced by digital interfaces like HDMI and DisplayPort, VGA is still found in older devices and some professional equipment due to its simplicity and broad compatibility. It typically uses a 15-pin connector, which is easy to recognize by its blue color and trapezoidal shape. However, VGA does not carry audio signals, so an additional connection is required for sound.
