What Does Video Graphics Array (VGA) Mean?
Video Graphics Array (VGA) is a display standard originally developed in 1987 by IBM for its PS2 range of computers. VGA’s single-chip design facilitated direct computer system board embedding with minimum requirements. Later, VGA became the de facto standard for graphics systems in PCs.
Techopedia Explains Video Graphics Array (VGA)
VGA was designed as an application specific and integrated circuit (IC) for analog signals, versus digital signals used in Monochrome Display Adapters (MDA), Color Graphics Adapters (CGA) and Enhanced Graphics Adapters (EGA) standards. VGA systems are not compatible with monitors built according to these older standards.
