When no configuration is provided to the driver, it will enable all connectors

It will use the highest resolution as provided by the BIOS or EDID information.
For each connector a separate Capture connection will be requested labeled
according to the connector name. When newly connected displays are detected
by the driver, the new connectors are enabled and another Capture session
labeled according to the connector will be requested.

The physical dimension of the display is reported as width_mm and height_mm
The physical dimension of the display is reported as 'width_mm' and 'height_mm'
in millimeter per connector and if available, also per mode. The values can
be used as input to DPI calculations. The currently used mode of the connector
is tagged in the report explicitly.
