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.
