Technically, the Steam Machine supports HDMI 2.1. However, Valve and AMD are not allowed to offer an open-source driver for it.

The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve’s Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations.

    Thunderbolt is exactly that.

    Thunderbolt 2 and Mini Displayport used to have the same connector. Since Thunderbolt 3, it now uses the USB C connector.

    Thunderbolt 5 supports Displayport 2.1. I wish more devices used Thunderbolt compatible USB C ports. Or GPUs came with a Thunderbolt port on them. They’re pretty awesome, it’s like better USB C.

    It seems like only laptops really use them to allow docking through a single cable

      You don’t need Thunderbolt for Displayport alt mode. It’s a separate spec that can also be implemented independently. I have a dock that’s not Thunderbolt but supports DP alt mode.

      But Thunderbolt has some additional stuff too
