NAME

       edid-decode - Decode EDID data in human-readable format

SYNOPSIS

       edid-decode [in] [out]

DESCRIPTION

       edid-decode  decodes  EDID  monitor  description  data in human-readable format.  It takes
       zero, one, or two arguments.  If invoked with no arguments it reads  from  standard  input
       and  writes to standard output.  With one argument, the file named by the argument is read
       instead.  With two arguments, normal output is suppressed, and the  binary  EDID  blob  is
       written to the file named by the second argument.

       Input  files  may  be  raw  binaries or ASCII text.  ASCII input is scanned for hex dumps;
       heuristics are included to search for hexdumps in xrandr(1) property  output  and  Xorg(1)
       log  file  formats,  otherwise  the  data  is  treated  as a raw hexdump.  EDID blocks for
       connected monitors can be found in /sys/class/drm/*/edid  on  modern  Linux  systems  with
       kernel modesetting support.

NOTES

       Not  all  fields  are decoded, or decoded completely.  Some fields' decoding may appear to
       corrupt the output (for example, detailed string  sections  have  their  contents  printed
       literally).   edid-decode  does  attempt  to  validate  its  input  against  the  relevant
       standards, but its opinions have not  been  double-checked  with  the  relevant  standards
       bodies,  so they may be wrong.  Do not rely on the output format, as it will likely change
       in future versions of the tool as additional fields and extensions are added.
