       get-edid,  parse-edid - read-edid tools to retrieve and interpret moni-
       tor specifications using	the VESA VBE DDC protocol

       get-edid	[OPTIONS] | parse-edid
       get-edid	[OPTIONS] > filename
       parse-edid < filename

       The read-edid utility comprises two tools: get-edid and parse-edid.

       get-edid	uses real mode calls to	perform	 Data  Display	Channel	 (DDC)
       transfers,  or Linux i2c	calls to perform Enhanced DDC transfers	to re-
       trieve information from	monitors,  including  identification  strings,
       supported  sync	ranges,	 available video modes,	and video mode parame-
       ters. Such information can be useful for	configuring  X	Window	System
       servers in certain cases.

       get-edid	 returns  the  raw Extended Display Identification Data	(EDID)
       block directly from the monitor,	so the parse-edid command is available
       to interpret it and generate a human-readable block of text information
       that can	also be	included in a X11 xorg.conf file.

       Generally the output of get-edid	is piped directly to parse-edid.

       New in version 3.0.0, get-edid takes a few options.

       -b BUS, --bus BUS
	      only scan	the i2c	bus BUS	(if built with i2c support)

       -c, --classiconly
	      only use the older VBE interface (if built with i2c and VBE sup-

       -h, --help
	      display a	basic help message

       -i, --i2conly
	      only use the newer i2c interface (if built with i2c and VBE sup-

       -m NUM, --monitor NUM
	      try to return information	about monitor number NUM (VBE only)

       -q, --quiet
	      do not output messages over stderr

       parse-edid still	does not take any options. --help will show you	 which
       options your build of read-edid supports.

       read-edid  is  originally  the  work  of	John Fremlin and others. Since
       1.4.2, the new maintainer and programmer	has been Matthew Kern.	Nearly
       all of the code for this	project, as well as this manual	page, has been
       rewritten for 3.0.0 by Matthew Kern. See	AUTHORS	for more details.
