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

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.
