       get-edid,  parse-edid  -  read-edid tools to retrieve and interpret monitor 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  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.


       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.
