S2817Q, XPS 15, setup help
Hi - just got a new Dell UltraHD Monitor S2817Q to use with my XPS-15 laptop and Thunderbolt dock. The monitor comes with USB, HDMI and DP cables. Which would be the best to use to connect the dock to the monitor and why? Thanks

Review the S2817Q User's Guide.
List all of the video out ports on the XPS 15 laptop. I would first forego the dock and connect the XPS 15 laptop directly to the S2817Q. This will show us the XPS 15 laptop video out port resolution capability. You may find that one port can do 3840x2160 60Hz while the other cannot. So test that first. Understand, a dock cannot "upgrade" the laptops video out ports.
The S2817Q USB upstream cable must be connected directly to the laptop USB port to give you usage of the two bottom USB downstream ports.
