AMD is bringing HDMI 2.1 support to Linux and Valve's Steam Machine. The update will arrive through the AMDGPU driver. This enables 4K 120Hz gaming and variable refresh rate (VRR) for higher bandwidth.

The Steam Machine features a custom RDNA 3 GPU. HDMI 2.1 support will allow the console to output at higher resolutions and refresh rates. The feature is expected to arrive soon.
HDMI 2.1 enables 4K 120Hz and VRR
According to Phoronix, the HDMI 2.1 implementation enables 4K 120Hz gaming and VRR. However, full HDMI 2.1 support has been delayed due to compliance and licensing issues. An AMD developer stated the code is ready but legal issues are pending.
The update positions the Steam Machine as a more capable living room gaming device. With HDMI 2.1, users can connect to modern TVs and monitors that support the standard. This brings the console closer to competing with other gaming platforms.
