Docking Station for XPS 7590

@Crruzer  See my replies in this thread.  The Surface Pro 5 doesn't support Thunderbolt 3, but it does support DisplayPort HBR3, whereas the XPS 15 7590 only supports DisplayPort HBR2.  So depending on the resolution(s) of the displays you plan to use, it might still be worth getting a Thunderbolt 3 dock to increase the capabilities of the XPS 15, while using that dock in USB-C backward compatibility with the Surface Pro 5.  If your displays are both 1920x1200 or lower, then a regular USB-C dock would work with both systems.  If they're both 2560x1440, you'll need a TB3 dock to run that from the XPS, but the Surface Pro 5 can run that even through a dock operating in USB-C backward compatibility mode.

@jphughan Both external monitors are currently 1920*1080 but that may be changing in the near future to something with a higher resolution.

We purchased a D6000 because we were told by a Dell sales agent that'd be the only Dell dock that had the ability to connect to an XPS 7590 & to a Surface Pro 5. The Surface Pro 5 only has a Mini DisplayPort (version 1.2) & USB 3.0 port outside of the SurfaceConnect port.

Is there a Dell Thunderbolt 3 docking station that the Surface Pro 5 could connect to then? If so, how?

@Crruzer  Ok, in that case you'd be looking at a solution along the lines of what I just helped a friend of mine set up.  It involves a device called a KVM (keyboard/video/mouse).  Essentially, you connect your display(s), USB peripherals that you want to be able to switch between your PCs, and your speakers all to the KVM's outputs, and then the KVM offers "banks" of inputs for two or more source devices.  If you're looking for futureproofing, here is a KVM that can support dual displays up to 4K 60 Hz each and two source systems.  This is the one I set up for a friend of mine.  The most convenient way to design this solution would be to connect your peripherals to the KVM and then connect docking stations for each of the source systems to the inputs of the KVM.  That way you maintain single cable connectivity between the systems and your desk.  But that of course requires buying the KVM and two docking stations.  The alternative would be to connect multiple separate cables, i.e. video, USB, and audio, from either or both of your systems directly to the KVM.  But then you lose single cable convenience, and since you'd be trying to run two displays from a Surface device that only has a single video output connector, the only way to do that would be to get displays that support being daisy chained.  In that case, the single Mini-DisplayPort interface from the Surface goes to a single DisplayPort input on the KVM, which feeds a single DisplayPort output of the KVM that has two displays hanging off of it.  But for bandwidth reasons, the most you can get on a dual display daisy chain from the Mini-DisplayPort output on that Surface is dual 2560x1440.  (Although in fairness I don't think you can run dual displays of anything higher than that through the Surface Dock either, at least not with that system.  Newer Surface devices can run dual 4K 60 Hz.)

If that's a setup you still think you might want to pursue, I can provide a bit more detail as to how it would work if needed.

@jphughan We definitely want the XPS optimized in every way while using a docking station.. Would there be a way to possibly split the monitor & speaker signal into two separate docking stations? One going into a docking station best used for the XPS & the other into a dock that would at least provide display & audio for the Surface Pro 5.

@Crruzer  That's the one you want.  The WD19S 180W would also work, but that dock when paired with a 7590 would be limited to dual displays up to 1920x1200 each.  So if you're planning to upgrade beyond that, the WD19TBS will be what you want.  It can handle dual displays up to 4K 60 Hz each, and it comes standard with a 180W adapter.  Those docks and the previous generation models they replaced are the only ones that will properly power an XPS 15.

@jphughan Perfect, thx! I'll probably get that one & then what I'll end up doing about the Surface Pro 5 is getting an HDMI splitter I can position easily on the desk somewhere, attach a short mini displayport on one end ready for that connection & a short displayport that's always connected to the docking station. Surface Pro really only needs one monitor & none of the other peripherals attached to docking station. Any ideas on what splitter I should be looking at?

@jphughan What would be the best docking station for the XPS 7590, that'll provide the best performance while running graphic intensive programs & utilize the 7590's GPU?

The only Dell Thunderbolt docking station online is this one currently.. that correct? Dell Thunderbolt Dock – WD19TBS

@Crruzer  An HDMI splitter takes a single source signal and delivers that image to two different displays.  The device you're describing would be an HDMI 2x1 switch, i.e. 2 inputs and 1 output.  Those aren't difficult to find, but there are also DisplayPort switches out there if you'll be using DisplayPort anyway.  But if you do use HDMI, then you may as well use the actual HDMI output on the WD19TBS itself, along with a MiniDP to HDMI adapter/cable from the Surface.  I don't have any specific products to recommend on those fronts, but you should find some options with the right search term.
