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.
What we want is a solution for customers who don’t understand the benefit of DP and won’t buy an adapter when there’s already HDMI ports on both devices.
