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.



Are people just forgetting it has a displayport also? Just ignore HDMI, they got greedy, onto the rubbish pile they go.
The people who block HDMI for Linux are also the people who make TVs and other media stuff. So you may not be able to use displayport or hdmi just because some rich people decided so to make more profit.
The problem is that many TVs have HDMI, but no DP.
Then buy a DP to HDMI 2.1 dongle
No problem for me, but many consumers don’t think that far.
Ok but I need a pretty expensive active adaptor for my tv?
Does it have VGA?
