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

SYNOPSIS
       edid-decode <options> [in [out]]

DESCRIPTION
       edid-decode  decodes  EDID  monitor  description	data in	human-readable
       format.	If [in]	is not given, or [in] is '-', then the	EDID  will  be
       read from standard input. If [out] is given then	the EDID that was read
       from [in] is written to [out] or	to standard output if [out] is '-'. By
       default	the  output  is	written	as a hex dump when writing to standard
       output or a raw EDID if written to a file.

       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 ker-
       nel modesetting support.

OPTIONS
       -h, --help
	      Prints the help message.

       -o, --output-format=_fmt_
	      If [out] is specified, then write	the EDID in format _fmt_.
	      The output format	can be one of:
	      hex: hex numbers in ascii	text (default for stdout)
	      raw: binary data (default	unless writing to stdout)
	      carray: c-program	struct

       -c, --check
	      Check if the EDID	conforms to the	standards.

       -e, --extract
	      Extract the contents of the first	block in hex values.  This was
	      always done in old edid-decode versions. To get the same	behav-
	      ior add this option.

NOTES
       Not all fields are decoded, or decoded completely.  Some	fields'	decod-
       ing may appear to corrupt the output (for example, detailed string sec-
       tions 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	exten-
       sions are added.

SEE ALSO
