AMD has taken an important step to fix one of the long-time problems for Linux users: the lack of full HDMI 2.1 support in open-source drivers.
For years, users with Radeon graphics cards were limited because the HDMI Forum did not allow sharing key technical details needed for open drivers. This made it hard to fully support HDMI 2.1, even on devices like Valve’s systems.
AMD Takes Big Step Toward HDMI 2.1 Support on Linux
Now things are starting to change. AMD has added new patches to the Linux kernel driver (amdgpu), bringing support for HDMI FRL (Fixed Rate Link), which is a key part of HDMI 2.1. Support for DSC (Display Stream Compression) is still being tested, so it’s not fully ready yet, but this is still a big step forward.
Companies like Valve helped push for this change, as they want their devices to fully use modern displays. With this update, AMD developers have improved the code and passed important tests, bringing Linux closer to the same level as Windows when it comes to HDMI 2.1 support.
This update is useful for people using high refresh rate monitors and 4K TVs at 120Hz, where HDMI 2.0 was a limitation. With future kernel updates, full support should arrive, allowing AMD hardware on Linux to finally reach its full performance.
