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

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

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

     get-edid uses real mode calls to perform Data Display Channel (DDC)  trans-
     fers,  or Linux i2c calls to perform Enhanced DDC transfers to retrieve in-
     formation from monitors, including identification strings,  supported  sync
     ranges,  available video modes, and video mode parameters. 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 inter-
     pret  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 support)

     -h, --help
	    display a basic help message

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

     -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  op-
     tions your build of read-edid supports.
