[NAME]  Based on the XPS 13's specs and your peripherals, you have lots of options.  Dell's dock would be the WD19S, but that may be more than you need and therefore want to pay for.  There's also the WD19TBS that supports Thunderbolt, but that's even more overkill if you're only trying to run a simple 1080p display, since even the WD19S when paired with your system can run dual 1440p displays or a single 4K 60 Hz display. (The WD19TBS would be able to run dual 4K 60 Hz displays or triple 1440p displays.)  In terms of third party options, CalDigit makes some solid docks, and the ones I'd suggest in your case would be the USB-C HDMI Dock.  Despite the name, that dock also supports Thunderbolt 3 (but is backward compatible with USB-C systems as well), and it has the same dual 4K 60 Hz capability as the WD19TBS.Otherwise, your setup is simple enough that you could even consider a USB-C multi-purpose hub, aka a "mini-dock".  Take a look at my answer in this thread where somebody else just asked almost the exact same question you did here.  If you need more USB ports than you can find in a mini-dock, you could always add a powered USB 3.0 hub and connect that through one of the USB ports on the mini-dock, in fact a powered hub can be useful anyway.  The other difference in your setup is that the XPS 13 9310 only needs a 45W power source for optimal performance, so if you wanted to use the USB-C power passthrough capability I mentioned in that thread without losing power to the "skim", you could probably get away with a wall charger of only 60W rather than 90W as I suggested in that other thread -- but 90W won't hurt anything if you want that type of charger for broader compatibility with other devices you might want to use it with.  Hopefully this helps!
Just had my laptop delivered this week and since it only has 2 thunderbolt ports was wondering what dock would work best with it. It would be just a simple setup, 1 Dell S2415H Hdmi monitor,wireless mouse, maybe keyboard and slots for a flash drive.Not sure if it needs to be powered or not. Any help would be great thanks!
