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
       communication 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
              stdout.

              --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
