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.

No, DisplayPort, DVI-D and HDMI use fundamentally the same protocol, HDMI just adds DRM which requires active adapters when one plugs in a HDMI source into a DisplayPort sink. DisplayPort to HDMI conversions are completely lossless and don't add latency AFAIK.

Oh wow, all that hassle just for some DRM, as if that would prevent anything... Thanks for clarifying ๐Ÿ‘
