9370 with WD19TB - will this work?

@thereisnothinglikeabmw-gmail.com  Yes that will work fine.  In terms of getting that setup working on non-Dell systems, if they support Thunderbolt 3, they'd be good to go.  If they're non-Thunderbolt systems, then their USB-C port would need to support at least USB 3.1 Gen 1 and DisplayPort Alt Mode (video output), both of which are optional capabilities on USB-C ports and not always implemented.  In addition, the video output capability would need to be DisplayPort 1.4/HBR3 over USB-C to be able to send enough video bandwidth to the dock in order to run QHD+FHD.  With a Thunderbolt system, you'd be fine even if the system only supported DP 1.2/HBR2 because Thunderbolt can carry two full DisplayPort interfaces.  USB-C when also running USB 3.x carries only half of a DisplayPort interface.

And then if you wanted to be able to charge the attached system from the dock, then the system would need to support being charged over USB-C/TB3, which is also an optional capability not always implemented, and they'd need to function on no more than 90W of power, which is the most the WD19TB will provide to non-Dell systems.

However, note that certain "specialized" features of the dock won't be available with non-Dell systems, and actually even some Dell systems, such as being able to use the dock Power button to control the system, as well as some enterprise features like PXE boot and MAC Address Passthrough.  And second, since this is the tech world, just because something SHOULD work doesn't mean that it always WILL, so even if your system meets the requirements I laid out, technically there's always the potential for certain combinations of equipment to cause strange interoperability problems that shouldn't exist but do anyway.
