NAME

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

SYNOPSIS

       get-edid | parse-edid
       get-edid > filename
       parse-edid < filename

DESCRIPTION

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

       get-edid  uses  Linux's vm86(2) system call to enter virtual 8086 mode and perform Data Display Channel (DDC) transfers using the VESA BIOS
       Extensions (VBE) to retrieve information from monitors, including identification strings, supported sync ranges, available video modes, and
       video mode parameters.  Such information is often useful for configuring X Window System servers such as XFree86.

       The  data  obtained by get-edid is in a binary format, 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 an XFree86 XF86Config file.

       It is customary to invoke get-edid and parse-edid together in a pipeline.

       get-edid and parse-edid accept no options, recognize no environment variables, read no input files, and create no output files.
