NAME
       xcmddc -	monitor	EDID fetching over i2c

SYNOPSIS
       xcmddc [	-l [-v]	]
       xcmddc [	-d POSITIONAL_NUMBER [--force-output] [--identify] ]
       xcmddc [	--i2c NODE_NAME	[--force-output] [--identify] ]
       xcmddc [-h]

DESCRIPTION
       The  xcmddc tool	fetches	a monitors EDID	data block over	a i2c communi-
       cation channel.

OPTIONS
       -l     list devices.  Only devices which	provide	a EDID data block  and
	      the EDID's header	is valid will be counted.

	      -v show each device by its node name.

       -d=POSITIONAL_NUMBER , -d POSITIONAL_NUMBER
	      position	in device list.	 The numbering of monitors starts with
	      zero for the first device. To get	the number  of	all  available
	      devices  use  "xcmddc -l". The EDID data block is	dumped to std-
	      out.

	      --force-output switch EDID header	verificatcationn off.

	      --identify dump the error	code as	integer	to stdout.

       --i2c=NODE_NAME , --i2c NODE_NAME
	      select the i2c device node file. The EDID	data block  is	dumped
	      to  stdout.  The --i2c option is much faster than	the -d option.
	      This is because of much fewer timeouts reuired for counting  the
	      valid i2c	device with the	-d option.

	      --force-output switch EDID header	verification off.

	      --identify dump the error	code as	integer	to stdout.

GENERAL	OPTIONS
       -v, --verbose
	      increase verbosity

EXAMPLES
       Count available i2c->monitor devices:
	      xcmddc -l

       List available i2c->monitor devices by name:
	      xcmddc -lv

       Dump EDID from first i2c	node:
	      xcmddc -d	0

       Dump EDID by i2c	device name:
	      xcmddc --i2c /dev/i2c-5

       Print a help text:
	      xcmddc -h
