Definition: EGA

(Enhanced Graphics Adapter) The second color display interface for the IBM PC, which debuted with the PC/AT in 1984 (it was superseded by VGA three years later). EGA was a digital display system that required an RGB Enhanced Color Display monitor. It boosted the previous CGA's 640x200 mode from two to 16 colors and added a 640x350 resolution. Third-party adapters increased resolutions to 640x400 and beyond. See CGA and VGA.
