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.



This is why many of the expensive Dock options from HP / Dell / Lenovo, etc come with a non-detachable USB-C cable. You can’t have the “wrong” cable because the one you need isn’t removable.
I really dislike that. But I understand the reaction to the failure of the usb org. Usb C cables must be labelled on the cable (repeating) with exactly what they support in standard terms.
Maybe another job for the EU.
