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) transfers,  or  Linux  i2c  calls  to
       perform  Enhanced  DDC transfers to retrieve information 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  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 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 options your build of read-edid
       supports.
