Hello!

I'm looking to purchase an XPS 13 7390, non 2-in-1 and would like to drive the following external monitor setup.

- Two QHD displays (U2719D) via DisplayPort daisy chained from one of the Thunderbolt 3 ports... AND...

- A third monitor, yet to be purchased.

My goal being to: Get the maximum resolution out of the third monitor, and do this as inexpensively as possible.  ie: I see some Thunderbolt docks, but they seem very pricey.  

Would I be able to buy another simple DisplayPort adapter cable and plug that into the second Thunderbolt 3 port - leaving the USB c port for charging the laptop?

Thanks in advance for any advice!
