The HDMI Forum continues to block open-source HDMI 2.1 driver implementation for Linux, forcing Valve's Steam Machine to be software-limited to HDMI 2.0 despite hardware support. This restriction prevents native 4K at 120Hz without compression and limits VRR functionality. AMD submitted a functional HDMI 2.1 driver in early 2024 but was rejected by the HDMI Forum. Valve confirms they're still working to resolve the issue, while users can work around limitations using chroma subsampling or active DisplayPort-to-HDMI adapters.
