Best docking station for XPS 13 7390 laptop?

@KSteck  Happy to help.  The D6000 actually would be compatible with your system, purely because it would be compatible with practically any system.  There's a reason Dell calls it a "Universal" docking station, which is a term they only use with their DisplayLink-based docking stations, namely the Dxxxx models.  And the reason they're called Universal is because all they require is a USB-C or USB-A "regular USB" connection plus DisplayLink software installed on the system, and DisplayLink software is available for Windows, Mac, and Linux.  Technically you could use the D6000 with non-Dell systems.  But "compatible" doesn't mean "optimal" by any stretch of the imagination.

(Incidentally, the WD19TB would work with non-Dell systems too, and even non-Thunderbolt systems, although at reduced functionality.  However, with non-Dell systems and even certain Dell systems that aren't "officially" compatible, some of the bonus features of the dock don't work, such as using the Power button on the dock to control the system power state.  But the XPS 13 7390 is officially compatible with the WD19TB, so you'll be able to use that -- which actually isn't possible on the D6000.  It only has a Sleep/Wake button, not a full Power button that works even from shutdown.)

Good to know. I looked at the specs for my P2418D monitors (2560x1440 resolution at 60 Hz). The input connectors are HDMI and DisplayPort, as well as a USB 3.0 upstream port. Dell supplies a DP cable and a USB 3.0 upstream cable, as well as a power cable. Is it safe to assume that I don’t need any new cables to attach the monitors to a Dell WD19TB docking station and have the monitors work? Thanks so much for your help. I feel as though I’m getting much better answers than I’ve gotten in months. 

@KSteck  Thanks for the kind words, even though I'm sorry to hear that you've been stuck for months.  If you only want video output to the displays, just connect each display to one of the DisplayPort outputs on the dock and you're done.  If you want to be able to use the USB ports built into either or both of the displays, then connect a USB 3.0 cable from the "upstream" port on the display to one of the USB 3.0 ports on the dock.  If you don't care about using the USB ports on one or both of the displays, you can skip using that cable in order to keep the dock's USB 3.0 ports free for other purposes.  Good luck!

Thanks for the suggestions. I have other peripherals that need to be connected to the laptop, such as a scanner and speakers. So, I think a docking station makes the most sense. I’ll check out the WD19TB. Appreciate your help!

@KSteck  Not sure what region you're in, but the Dell US store link to the WD19TB is here.  But if you want to look at third party options, yes other Thunderbolt 3 docks should be fine.  CalDigit has some popular options, namely the TS3+ and the USB-C Pro Dock, the latter of which despite the name will take advantage of Thunderbolt 3 capabilities if the attached system supports it.

However, be aware that with third party options, you won't have a Power button on the dock that can be used to control your system, including powering it up from shutdown with the lid closed, if that type of thing would be useful to you.  There isn't an industry standard for that yet, so that functionality requires the dock and system to support each other, i.e. Dell docks and Dell systems.  And the WD19TB is one of the few Thunderbolt docks currently on the market that supports DisplayPort 1.4 rather than the more common 1.2, and it's also backward compatible with non-Thunderbolt systems.  Admittedly neither of those things matters for the XPS 13 7390 since it only supports DP 1.2 and does support Thunderbolt, but the WD19TB might be a better choice from a futureproofing and broader compatibility standpoint perspective.  (For comparison, neither of the CalDigit docks I mentioned support DP 1.4, and the TS3+ requires TB3 and won't work at all with non-Thunderbolt systems.  The USB-C Pro Dock is backward compatible with USB-C systems at reduced functionality, but you wouldn't be able to run dual QHD displays in that case.  The only way to do that with a non-Thunderbolt system would be with a system and dock that both supported DisplayPort 1.4 over USB-C.)

But if you want to look at third party options and are only concerned about getting the most out of your current system, you'd just want to look for Thunderbolt 3 support, support for running up to dual 4K 60 Hz displays (which indicates that the dock can tap into dual GPU interfaces when available over TB3, which the XPS 13 systems can provide), and support for providing at least 45W of power, which is what the XPS 13 is designed for.  Both of the CalDigit docks I mentioned meet those requirements, although with the TS3+ you'd have to get a USB-C to DisplayPort cable to connect one of your displays, since it only has one DisplayPort output and one USB-C output that supports video rather than dual DisplayPort outputs.

@KSteck   Based on the missing page (even the linkd @jphughan provided is broken), I'm wondering if there was a problem with the Dell Business Thunderbolt Dock - TB16 with 180W Adapter, and it was either recalled or discontinued.

@jphughanI'm hoping you can help.  I purchased a Dell XPS 13 7390 in December 2019.  The Dell rep recommended getting the D6000 dock, but I didn't want a universal dock.  After much research (mostly trying to find the correct compatible dock), I purchased the Dell Business Thunderbolt Dock - TB16 with 180W Adapter in March 2020. It seemed okay, at first, but the past few months, I noticed that my laptop gets overheated and dies after being plugged into the dock for a while.  The dock is plugged into a surge protector power strip, along with other equipment. 

Today, when I opened the lid of my computer, the screen was lit dark gray, the laptop was hot, the fan was running, but I couldn't reboot or shutdown.  When I closed the lid, the screen stayed lit dark gray and the fan continued running. I unplugged it from the dock, no change.  I had to wait until the laptop cooled down before it would boot up again - which took quite a while.

I powered down the dock, but when I tried to power it up again, the power light would flash, it would make a quick "whoosh" sound, then go dark.  Now, the dock won't even turn on.  This is an expensive piece of equipment to just go dead like this in such a short time, and I'm not sure if it has done damage to the my laptop.  This was supposed to be "the" compatible dock for this laptop.  What can be done to resolve this issue?  Thank you...

@justd103  Unfortunately I don’t know how to account for that behavior. I do know that laptops can run a bit louder and hotter when connected to Thunderbolt peripherals because the system’s Thunderbolt controller can be a bit power-hungry, but it definitely shouldn’t end with the dock not powering on. As for the laptop, I’ve had cases where the display will be gray like that, often after I’ve been using my system via Remote Desktop and try to use it locally afterward. I don’t know if it’s a Windows issue or a GPU driver issue, but I’ve seen it very occasionally on multiple systems. Sorry I can’t provide any more insight than that!

@justd103  The TB16 was discontinued years ago. It was replaced by the WD19TB in 2019, then the WD19TBS somewhere in 2020 I think (it removed the headset jack because that became a supply problem during the semiconductor shortage), and more recently the WD22TB. I’m not sure how you got a new TB16 recently. Its predecessor the TB15 was recalled due to stability and reliability issues, but not the 16. 

@jphughanThank you for the info...  I just checked my purchase history from Dell, and the item that it says was purchased was Dell Business Thunderbolt Dock - TB16 with 180W Adapter in March 2020.  However, after reading your reply, I checked the model # printed on the bottom of the dock, and it says WD19TB, so I don't know what's going on.  All I know is I paid a lot of money for this piece of junk and it doesn't work.  Very poor quality, and now I'm stuck because I need the dock for my network cable and my headset.  I had to buy an A to C adapter for the dongle so I could use my wireless mouse.

Thank you, @jphughan I appreciate your taking the time to thoughtfully respond.  I'm very disappointed with this product.
