Dell WD19 User Manual page 18

Display Port Available Bandwidth
HBR3 (HBR3 x2 lanes - 12.9 Gbps)
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 judgement 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).
NOTE: Resolution support is also dependent on the monitor's Extended Display Identification Data (EDID) resolution.
