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.


Wild to see DisplayLink among the companies here.
I was confused by seeing DisplayLink there, but couldn’t fully place them, and Wikipedia made me think they may be using HDMI and have an interest in keeping it inaccessible to sell their products and services.
Knowbe your enemy, they say.But jokes aside, I believe DisplayLink’s focus is primarily on the client<->docking station part, with docking station<->monitor usually still being HDMI/DP (same with direct client<->monitor links). So they still have to interface with it some way or another.
