      IBM and others have introduced a
     bewildering plethora of graphics and text display standards
     for IBM PCs.  The standards are mostly implemented by
     plugging in a video display board (or "{graphics adaptor")
     and connecting the appropriate monitor to it.  Each new
     standard subsumes its predecessors.  For example, an EGA
     board can also do CGA and MDA.
     With the PS/2, IBM introduced the VGA standard and built
     it into the main system board motherboard.  VGA is also
     available as a plug-in board for PCs from third-party vendors.
     Also with the PS/2, IBM introduced the 8514 high-resolution
     graphics standard.  An 8514 adaptor board plugs into the PS/2,
     providing a dual-monitor capability.
     Graphics software had to support the major IBM graphics
     standards and many non-IBM, proprietary standards for
     displays.  Either software vendors provided display drivers
     or display vendors provided drivers for the software package.
     In either case, switching software or switching display
     systems was fraught with compatibility problems.
