     <hardware> 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 has to support the major IBM graphics
     standards and many non-IBM, proprietary standards for
     high-resolution displays.  Either software vendors provide
     display drivers, or display vendors provide drivers for the
     software package.  In either case, switching software or
     switching display systems is fraught with compatibility
     problems.
