AMD is making progress on adding HDMI 2.1 support to its Linux amdgpu driver, including HDMI FRL for higher bandwidth and features like dynamic HDR and Variable Refresh Rate. While still missing Display Stream Compression support for the highest resolutions, this development is particularly beneficial for Steam Machine users and Linux gamers. The update represents a significant step toward full HDMI 2.1 compliance on Linux systems.
Background
HDMI 2.1 is a display standard introduced in 2017 that enables higher resolutions, faster refresh rates, and features like Variable Refresh Rate. Linux support for HDMI 2.1 has been limited due to licensing and driver development challenges.
