Valve’s Steam Machine Continues Without HDMI 2.1 Integration

The Valve Steam Machine represents a hybrid device combining console-like functionality with PC capabilities, running SteamOS, a Linux-based operating system.

Despite the hardware compatibility, the HDMI-Forum restricts open-source driver implementation for HDMI 2.1 under Linux, limiting features like VRR and optimal 4K 120Hz output.

Valve's device supports 4K at 120Hz using chroma subsampling, which compromises color quality, although DisplayPort connectivity offers alternative solutions.
