EGA or Enhanced Graphics Adaptor is an effort to unify features of a variety of display adaptors. The EGA combines all the features of the above adaptors and provides higher resolutions. It supports upto 16 colors at a time. The EGA could have been a replacement for the other adaptors except for the fact that it is expensive and is not supported by specific software provided by some vendors. An EGA usually has a resolution of either 640 x 200 pixels or 640 x 350 pixels. In order to make the best use of an EGA, you need to use a high quality color monitor.
