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 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.
