    USB-C is already a plug standard for display port over thunderbolt. Apple monitors use this to daisy chain monitors together.

      But its DP implemented within USB, vs an actual DP. There’s a latency there which might matter for online realtime gaming

        The USB-C is just the connector. The cables are thunderbolt. Thunderbolt 3 and 4 are several times the speed of USB 3.2. No latency issue.

          Yeah but there are still signal processing steps required to tell both ends of the connector which pins to use to implement the DisplayPort protocol.

          • DP cable? Connection is direct from GPU → Screen.
          • DP through USB? Connection has to go through the USB bus on the machine → Screen.

          Let’s hope that bus is dedicated, and not overloaded with other USB tasks!

            It is. That’s always been one of the key features of thunderbolt. There’s no negotiation or latency involved after you plug it in. It just works.

              Right, the pins just automatically know which to use without any negotiation from the USB bus. Come on.

                Just because you don’t know how any of this works, don’t lash out at me in anger.
