@username Thank you for sharing this new bidirectional DP to USB-C cable. I believe it's similar to the Moshi DP to USB-C cable. There's a fine print on Moshi specs stating the USB-C monitor has to accept a DisplayPort signal over USB-C (UFP_D pin assignment E). You can read this discussion on the Moshi cable.

The Moshi cable is also bidirectional and is VESA certified for HBR3 speed ([email protected]).

I would consider the monoprice cable if someone handed it to me free.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

It works but you need to disconnect the device your not using. Defeats the purpose of two TB3 ports but it works.

I received this Monoprice bidirectional DisplayPort to USB-C cable this week. It works when connecting self-powered monitors. I connected RX Vega 56 eGPU DP output to USB-C input on a Samsung C34J79x monitor. When connecting to a bus-powered monitor such as ASUS MB16AC, it does not work because the cable carries no power.
