Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -v, --verbose         show what's happening
  -q, --quiet           be quiet and only show errors
  -r RESOLUTION, --resolution=RESOLUTION
                        set resolution, e.g. "800x600", or "auto" to detect
                        the highest common resolution. For extend it is
                        possible to enter a single resolution for all
                        displays, or a comma-separated list of resolutions
                        (one for each display), or "max" to use the maximum
                        resolution for each device. Beware that many displays
                        advertise resolutions they can not fully show, so
