AMD's efforts to improve its open-source Linux graphics driver (AMDGPU) by incorporating HDMI 2.1 features have faced a significant obstacle. Despite extensive internal development aimed at enabling crucial functionalities such as 4K@120Hz and 5K@240Hz, the HDMI Forum has rejected AMD's proposal.
AMD's Proposal Rejected
The rejection has implications for Linux users with newer AMD Radeon graphics cards, who may find themselves unable to fully exploit the capabilities of HDMI 2.1-enabled displays. AMD conveyed its disappointment with the Forum's decision, emphasizing that achieving an open-source HDMI 2.1 implementation would be unfeasible without infringing upon HDMI Forum stipulations.
Legal and Compliance Concerns
The HDMI Forum justified its decision based on legal and compliance concerns related to the open-source dissemination of the HDMI 2.1 specification. This development underscores the challenges encountered by open-source HDMI developers following the HDMI Forum's move to restrict its specifications in 2021.
Recommendation for Linux Users
Consequently, the latest HDMI features are expected to remain inaccessible through open-source drivers. AMD's suggestion for Linux users seeking features like high-refresh-rate 4K gaming is to opt for DisplayPort connections as an alternative.
Windows Users Unaffected
In contrast, Windows users with AMD graphics will continue to enjoy full HDMI 2.1 functionality, underscoring a disparity within the open-source development landscape. This discrepancy also sheds light on potential tensions within the relationship between AMD and the HDMI Forum.
Uncertain Future for Linux Users
The rejection raises questions about whether Linux users with AMD graphics will ever harness the full potential of next-generation HDMI 2.1 displays. Currently, both AMD and the HDMI Forum seem entrenched in their respective stances, limiting choices for consumers and leaving the situation unresolved.
