- Valve's Steam Machine supports HDMI 2.1 hardware but is software-limited to HDMI 2.0 due to HDMI Forum restrictions.
- HDMI Forum refuses to disclose HDMI 2.1 specifications, blocking open-source driver development for Linux.
- Valve and AMD have attempted to submit a functional HDMI 2.1 driver but were rejected by the HDMI Forum.

- Current workarounds include using DisplayPort 1.4 to HDMI 2.1 adapters, though they lack official VRR support.
