AMD is updating its open-source AMDGPU driver to enable HDMI 2.1 FRL support by default in the upcoming Linux 7.4 kernel, following earlier patches for HDMI 2.1 features.

Why it matters

This update will improve the user experience for Linux users who want to take advantage of the higher resolutions and refresh rates offered by HDMI 2.1.

AMD is making it easier for Linux users to use the HDMI 2.1 feature by default in the upcoming Linux 7.4 kernel, which will allow for higher resolutions and refresh rates.
