Valve: HDMI Forum Continues to Block HDMI 2.1 for Linux (www.heise.de)

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.

I'm not sure where you're getting your information, but displayport absolutely supports audio. In most of the same formats that HDMI does as well.

Also, I've only ever had issues with HDMI plugs. All the displayport plugs I've used had positive locks on them and have been the most reliable plugs I've ever had to use aside from BNC connections.

You could perhaps have instead gone with "you don't find displayport on cheap consumer displays," because that's an accurate statement. That's a huge part of why this is a big deal.
