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.
While infuriating, I think people who care about features limited to hdmi 2.1 are people having monitors with display port and people who use the box as console on “normal tv” are happy with 4k60
But I hate, that there is no wide supported open video protocol…
