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: Configuration that is supported with AMD and Nvidia in special-graphics mode. This mode is listed in the BIOS
for the Dell Precision mobile workstations 7530/7730 will require enabling special-graphics mode when Switchable is
enabled.
Precision 7530 and Precision 7730 with AMD Graphics can only support dual 4K@60 Hz non-HDR monitors when, both
monitors are plugged to the two DP ports (not HDMI).
Precision 7540 and Precision 7740 with AMD Graphics can support up to six displays dependent on GPU capability. With
Nvidia Graphics, it can support up to four displays.
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).
