HDMI Forum to AMD: Navigating the Digital Crossroads
HDMI Forum : The world of digital connectivity is a labyrinth of standards, protocols, and proprietary secrets. Amidst this intricate web, the HDMI (High-Definition Multimedia Interface) standard has emerged as a ubiquitous conduit for transmitting audio and video signals. But what happens when the guardians of this standard lock horns with a tech giant like AMD? Buckle up, because we’re about to delve into the saga of the HDMI Forum and its standoff with AMD.
The HDMI Odyssey
Picture this: You’re a Linux enthusiast, wielding your trusty AMD graphics card, ready to unleash pixel-perfect glory on your high-resolution monitor. But alas, the path to visual nirvana is fraught with obstacles. The HDMI Forum, that enigmatic licensing group, stands guard over the HDMI standard. Their decree? No open-source implementation of HDMI 2.1 (or HDMI 2.1+). Translation: AMD’s FreeSync dreams over HDMI connections—like 4K at 120 Hz or 5K at 240 Hz—are dashed against the rocky cliffs of proprietary exclusivity.
Alex Deucher’s Quest
Enter Alex Deucher, an AMD engineer with a penchant for open source. For years, he’s been wrestling with the HDMI Forum, trying to find a chink in their armor. In January 2021, Deucher discovered that the HDMI 2.1 specification was locked away, like a forbidden tome in a crypt. Undeterred, he persisted, keeping a bug thread alive, hoping for a breakthrough. His mission? To deliver AMD’s magic to the Linux masses while toeing the line of legal obligations.

The Legal Quagmire | HDMI Forum
Fast forward to February 2023. Deucher’s legal dance with the HDMI Forum continues. “Basic functionality up and running,” he reports. But the real challenge lies ahead: exposing features without invoking the wrath of the HDMI overlords. Summer fades into fall, and the decision rests in the hands of—you guessed it—the HDMI Forum. Drumroll, please. The verdict? Rejected. No open-source HDMI 2.1 implementation allowed. The Forum’s gates remain firmly shut.
Membership Has Its Price
Here’s the twist: Membership in the HDMI Forum costs a cool $15,000. AMD’s on the list, but that doesn’t mean they’re handing out HDMI 2.1 blueprints like candy. The fine print? Airtight. No public implementation, no matter how tantalizing the Linux horizon. Rumors swirl—media firms fearing video piracy, perhaps? But let’s not dwell on barn doors and departed horses. The reality? DisplayPort emerges as Linux’s beacon of hope, while AMD contemplates its next move. Closed-source drivers or alternative paths? Decisions, decisions1.
Conclusion: The HDMI Crossroads
As the sun sets on this digital drama, we bid adieu to dreams of open-source HDMI 2.1. AMD’s loyal disciples must seek solace elsewhere. But fear not, for pixels shall dance, and screens shall shimmer. The HDMI Forum remains unyielding, and AMD stands at the precipice. So, dear reader, next time you plug in that HDMI cable, remember the battle behind the scenes—a clash of standards, a tussle for control. And may your pixels be forever sharp, whether over HDMI or DisplayPort. 🌟
