[NAME]  Short version: If you want 4K 60 Hz without an actual Thunderbolt peripheral, you can't use an adapter that does anything other than providing a video output off that USB-C port. So you can either achieve your other desired connectivity through a USB-A port, or get an actual Thunderbolt device (not "Thunderbolt-compatible") that can leverage enough bandwidth to run 4K 60 Hz (or actually dual 4K 60 Hz) and still have enough for USB 3.x and related traffic such as Ethernet.If you want to understand why, see this explainer post I wrote long ago because this topic was coming up often even back then, and it still does years later. 
Hello - I have an older XPS from 2017 model 9560. I have read most of the posts on here about the lack of hdmi 2.0, and how you can achieve 4k @ 60hz over a usb-c to display port cable but none of them quite solve my issue. I am hoping to find a dock that I can use that will provide me at a minimum - an ethernet port, and a 4k60hz hdmi port. HDMI is important because I have no DP on a projector that I would like to use. I don't need PD as I don't mind having to still plug my laptop in directly.I purchased one online that I thought would work, [URL] it does not give me more than 30hz. I suspect the problem might be that this claims to be "Thunderbolt Compatible" which means it doesn't actually use thunderbolt. On the otherhand this whole thunderbolt/usb-c thing is so confusing compounded with the fact that the 9560 only uses 2 lanes of PCI-e that I'm not sure this model supports 4k[NAME] + ethernet at all.Is there anyone that can definitely answer the question as to why I can't get 4k[NAME] over HDMI through the thunderbolt port and will something like a TB16 provide that through its HDMI port ( or will TB16 only provide 60hz over the display port)?
