[NAME]  The WD19TBS is your only option. It’s the only current dock model that will provide 130W to your system as needed for optimal performance AND that can run a 4K 60 Hz display from a DisplayPort HBR2 system like yours. It will actually run two.
Hello, A bit of a computer novice here, I am in the middle of looking for a docking station to connect my Dell XPS 15 9500 and the Dell U2720Q monitor. Does anyone happen to know the best docking station for connecting these two together? Sadly I thought that the XPS 15 and the U2720Q monitor would be able to have everything powered via a single USB-C cable but unfortunately, the laptop will not be running at its full power requirements (i.e if I wanted to watch 4K video, it'll be a bit laggy). In looking through the discussion, I've heard that the dell WD19TBS would be the best for this requirement. Regards, B
