So… the same connector as Thunderbolt, and it can deliver video like Thunderbolt. And in both cases it’s running DisplayPort over the connector.

So there were two different ways to run DP over a cable with a USB-C connector.

Sounds like it’s good it’s dead.

No, HDMI alt mode was (is?) actually sending HDMI over the USB-C wire.

Thunderbolt also doesn’t really natively send DP over USB; it encapsulates it (plus PCI express) in a custom wire format.

Only DP alt mode actually uses DisplayPort at the wire level over USB-C cables or ports.
