"AMD's Ambitious Plan for Open-Source HDMI 2.1 Driver Hits Roadblock: HDMI Forum Objects"

Linux users facing resolution and speed limitations compared to Windows and DisplayPort." Phoronix reported HDMI Forum's withholding of HDMI 2.1 spec access in January 2021.

AMD's Alex Deucher tackled legal concerns on HDMI 2.1 compliance from February 2023. Basic functionality was achieved by April 2023, but legal reviews continued.

By October, the HDMI Forum's decision shaped the fate of open-source HDMI implementations. Deucher's ongoing efforts exemplify the challenges in navigating legal complexities for open-source projects.

Ars Technica has initiated contact with the HDMI Forum, AMD, and Deucher for additional insights and plans to update the article accordingly. X.org has been reportedly involved in negotiations with the HDMI Forum, adding complexity to the ongoing discussions.

Membership fees for the HDMI Forum start at $15,000, potentially affecting the availability of certain specifications for public use.

Speculation from various sources, including Phoronix, suggests concerns from media companies regarding digital video ripping, although details are limited.

Given HDMI limitations, DisplayPort emerges as the preferred option for Linux users seeking optimal output, prompting AMD to consider options for implementing newer HDMI support within closed-source Linux drivers.
