USB C hub for thunderbolt 3 monitor


Standard Member
I have a C34J791 Samsung thunderbolt 3 monitor and a macbook pro 2017. The monitor provides power to the mac with a single cable connection. I also need to use an ethernet connection. Ideally I’d like to have a single hub that I can connect to my mac and connect both ethernet and the thunderbolt 3 monitor. Does such a thing exist? I can’t find one, I can find lots that allow you to drive HDMI, Displayport and VGA, but none drive a USB-C / Thunderbolt 3 monitor.

Thunderbolt 3 shares a lot of features and compatibility with USB including the video connection (DisplayPort) and power standard (USB-PD). That's why it went to the same connector.

If the monitor is not using any Thunderbolt-specific features then it may work with a USB Hub that supports USB-PD and DP Alt Mode.
