Understanding USB-C vs Thunderbolt confusion

[Someone]

Just a brief update, it looks like it's possible to run the monitor I purchased at 3440x1400 @ 100hz using DP over USB-C in "high resolution" mode, at the expense of a speed reduction over the built-in USB hub and ethernet port.

So the DP takes over all the signalling on the high speed pairs and the USB connection drops back to a USB-2 ?

I'm not entirely sure. I haven't had time to do proper testing with some high speed SSDs. I probably won't get to it this year, but when I do, I'll report my findings.

Even if it is USB 2.0 speeds, that's perfectly fine. The hub in the monitor is only being used for keyboard, mouse and a webcam. Any drives generally get plugged directly into the machine itself and the ethernet port isn't being used as Wi-Fi is faster.
