NAME

       ddcui - GUI for ddcutil

SYNOPSIS

       ddcui [options]

DESCRIPTION

       ddcui provides a graphical user interface to a monitor's Virtual Control Panel (VCP).  It uses the DDC/CI
       protocol  on an I2C bus connected to the monitor.  Normally, the video driver for the monitor exposes one
       or more I2C buses as devices named /dev/i2c-n.

       Virtual Control Panel features are defined in the Monitor Control Command Set (MCCS).  Monitors implement
       some subset of these features.  Each feature is identified using a single byte.  For example, feature x10
       is the brightness control.

OPTIONS

   Options that change initial settings for the Feature Selection dialog:
       --feature-set name
              Initial feature set to show.  The most  important  are  MCCS  -  all  features  defined  in  MCCS,
              MANUFACTURER  -  features  in  the  manufacturer  reserved  range  xe0..xff, COLOR - color related
              features.  For a complete list, use the --help option.  Unless --custom-feature-set is  specified,
              the default is MCCS.

       --custom-feature-set (feature code..)
              Explicitly specify the features to be shown.  Features in the feature code list are specified as 2
              byte  hex numbers, with or without leading "x" or trailing "h".  To specify more than one feature,
              separate the feature codes by commas or blanks, and enclose the entire list  in  quotation  marks.
              For example:
              --custom-feature-set "10 x12 14h"

       --only-capabilities
              Restrict  features  to  those  in  the capabilities string.  Applies when the feature set is MCCS,
              COLOR, or MANUFACTURER.

       --all-capabilities
              Always include features found in the capabilities string.  Applies when the feature set is MCCS.

       --show-unsupported
              Display  unsupported features in the feature set.  Normally unsupported features are not shown.

   Option that changes initial settings for the NC Values Source dialog.
       --nc-values-source MCCS|CAPABILITIES|BOTH
              Source of values shown in the drop down menu for simple Non-Continuous features.

       --use-latest-nc-values
              Always use values from latest MCCS version

   Option for initial display selection:
       --model model-name
              Model name as specified in the monitor's EDID and shown on the toolbar.

   Miscellaneous options:
       --styles
              List available Qt styles

       --style style-name
              Select the Qt style to use

       --version, -v
              Report version information

       --help Get command line help.

   Options that are passed to the ddcutil shared library.
       These correspond to ddcutil command line options of the same name.

       --ddc  Report DDC protocol and data errors to the terminal.

       --trace trace-group-name
              Trace all functions in a trace group.  May be specified more than once.

       --trcfile simple-file-name
              Trace all traceable functions in a file.  May be specified more than once.

       --trcfunc function name
              Trace a single function.  May be specified more than once.

       --timestamp | --ts
              Prefix trace messages with timestamp

       --thread-id | --tid
              Prefix trace messages with thread id

STATUS CODES

       Normally returns 0, returns 1 if failure.

       Using the --help option is regarded as success.
