NOTE: HDMI2.0 and MFDP (Multi-Function DisplayPort) Type-C ports on the back of all docks in the WD19 family are toggled. HDMI2.0 and MFDP Type-C cannot support dual monitors simultaneously. Only one of these ports can be used as a display device at a time.
NOTE: If higher resolution monitors are used, the Graphics driver makes a judgment based on monitor specifications and display configurations. Some resolutions may not be supported and so will be removed from the Windows Display Control Panel.
NOTE: Linux operating system is unable to physically turn-off built-in display, the external display numbers will be one less than the display numbers listed in above tables.

If the Display Port Data Rate is HBR2, then, the maximum resolution that Linux supports is 8192 x 8192 (counted with built-in display plus external display).

WD19TB for Thunderbolt systems with HBR2:
  1. If the built-in display resolution is FHD (1920 x 1080 @60 Hz), two external displays with QHD (2560 x 1440) @60 Hz could be supported.
  2. If the built-in display resolution is 4K (3840 x 2160 @60 Hz), only one external display with QHD (2560 x 1440) @60 Hz could be supported.
NOTE: Resolution support is also dependent on the monitor’s Extended Display Identification Data (EDID) resolution.
NOTE: The 5K resolution support is only available in either of these conditions:
  1. With discrete graphics mode only, or special graphics mode, or
  2. Using the Thunderbolt 3 Type–C to a dual DisplayPort adapter.
NOTE: Configuration that is supported with AMD and Nvidia in discrete-only mode or special-graphics mode. These modes are listed in the BIOS for the Dell Precision mobile workstations 7000 series and will require disabling switchable graphics for discrete-only mode or enabling special-graphics mode when Switchable is enabled. If the system does not have these options in the BIOS, then four monitors are NOT supported.
