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.

    Why though? It’s immediately clear where a VGA or hdmi cable works, but a USB-C could support or not support anything.

      So could an hdmi cable, there a lots of different hdmi specs as there are usb c specs. The problem is the lack of standardized labeling not the cables shapes. USB-C for everything would personally be my preference

        You also need cable markings, as both the cable and the port decide what specs to implement, and if they’re standard compliant or not.

        Plus there are active/inactive cables for thunderbolt (and I think usb4) which massively affect performance.

        USB c is better than the shitty port designs of USB before it, but it’s a huge mess.
