Can anybody please confirm whether I can connect a Dell U2719DC monitor to this laptop via USB-C providing charging and full USB 3.0 speed, and also daisy chain a U2719D via DisplayPort? i.e. I want two QHD displays, USB 3.0 hub and charging over a single cable. The processor in this laptop supports DisplayPort HBR3 so it should be possible, but I can't find a confirmation anywhere.
Re: Dell XPS 13" 9300 with dual monitors over USB-C?
As you say, all of the documentation suggests it will work. The U2719DC supports DP 1.4/HBR3 on its USB-C input, and it has a daisy-chain output, and the XPS 13 9300 supports sending a DP 1.4 over USB-C. Hopefully you can get someone to confirm via actual testing, but if not, if I were in your position I wouldn't hesitate to buy that set of equipment and would fully expect it to work. And of course if you do test, please report back for the benefit of anyone else who might find this thread while seeking confirmation.
