U2717D, daisy chain, HDMI?

@wkrinsky  as you found, DisplayPort MST / daisy chaining requires native DisplayPort signaling along the entire chain, no conversions allowed anywhere.  However, your new system has a USB-C port, and if the USB-C port supports video output -- which is optional on USB-C ports and not always implemented! -- then it would use DisplayPort.  In that case, you could get a USB-C to DisplayPort cable to connect to the first display in the chain.  I personally use this exact setup with a pair of U2717D displays to connect to various systems.  Unfortunately even after looking at both the Specs section of the product page and the data sheet PDF for that system, I just see that it says USB-C, without any indication of what capabilities it supports.  That's frustrating, because technically the only mandatory portion of a USB-C port is USB 2.0.  USB 3.1 Gen 1 or 2, video (called DisplayPort Alt Mode), and USB Power Delivery (both incoming for system charging and outgoing for running higher power devices) are all optional capabilities, so normally spec sheets will indicate which capabilities a system's USB-C port actually supports.

But if you don't have video output available over USB-C from that system, then the only native video output on that system seems to be HDMI, which can't run multiple independent displays.  In that case, your only option would be to connect one display that way and then use a USB adapter that relied on "indirect display" technology such as DisplayLink (not to be confused with DisplayPort) to connect the second display.  The issue is that the way DisplayLink work comes with some drawbacks, which I wrote about in detail in the post marked as the answer in this thread.  On the other hand, if that's your only option, you might decide that having a second external display is better than not having one.
