       get-edid,  parse-edid  -  read-edid  tools  to  retrieve  and interpret
       monitor specifications using the VESA VBE DDC protocol

       The read-edid utility comprises two tools: get-edid and parse-edid.

       get-edid uses Linux’s vm86(2) system call to enter  virtual  8086  mode
       and  perform  Data  Display Channel (DDC) transfers using the VESA BIOS
       Extensions (VBE)  to  retrieve  information  from  monitors,  including
       identification  strings,  supported sync ranges, available video modes,
       and video mode  parameters.   Such  information  is  often  useful  for
       configuring X Window System servers such as XFree86.

       The  data obtained by get-edid is in a binary format, so the parse-edid
       command is available to interpret  it  and  generate  a  human-readable
       block  of  text  information  that  can  also be included in an XFree86
       XF86Config file.

       It is customary  to  invoke  get-edid  and  parse-edid  together  in  a

       get-edid  and  parse-edid  accept  no options, recognize no environment
       variables, read no input files, and create no output files.


       get-edid and parse-edid were written by John  Fremlin,  Dan  Hugo,  and
       Martin  Kavalec,  using the LRMI (Linux Real-Mode Interface) library by
       Josh Vanderhoof.  This manual page was  written  by  Branden  Robinson,
       originally for Debian GNU/Linux.
