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  ar-
       guments	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 ker-
       nel modesetting support.

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.
