HDMI Forum Denies AMD's Open Source HDMI 2.1+ Driver Proposal

The HDMI Forum's rejection of AMD's proposal leaves Linux users without advanced HDMI 2.1+ features, pushing DisplayPort as the alternative.

AMD's request for open-source HDMI 2.1+ support was rejected by the HDMI Forum, affecting Linux users' access to high-resolution and high-frame-rate features.
Linux users are advised to use DisplayPort instead, as it remains unaffected by the HDMI Forum's restrictions.
The HDMI Forum's decision is based on legal requirements and concerns over exposing HDMI information to the public.
AMD has spent years attempting to resolve Linux compatibility issues with HDMI 2.1, but its efforts have been thwarted by the HDMI Forum's stance.
The rejection impacts users of AMD's graphics cards, limiting their ability to utilize HDMI 2.1+ features such as 4K@120Hz and 5K@240Hz.
