AMD Readies Full Open-Source HDMI 2.1 Support for Linux

3 hours ago

AMD is preparing full open-source HDMI 2.1 support for Linux through kernel patches, focusing on the Fixed Rate Link (FRL) feature to enable higher bandwidth for resolutions like 4K at 120 Hz and 5K at 240 Hz.
Valve has been involved in negotiating with the HDMI Forum to gain approval for open-source implementation, leveraging its use of AMD hardware in SteamOS and Steam Machines.
The HDMI Forum previously rejected AMD's open-source efforts, claiming it would violate fair use requirements, but recent developments suggest progress after years of work and pressure from companies like Valve.
