If would need to be patched in on Linux kernel level, which is annoying to say the least.
Comment on Why won’t Steam Machine support HDMI 2.1? Digging in on the display standard drama.

Not that easy.
To get HDMI 2.1 support for the Gabe Cube itself essentially requires kernel level patches. Which on a “normal” Linux device is possible (but ill advised) but on these atomic distros where even something like syncthing involves shenanigans to keep active week to week? Ain’t happening. Because HDMI is not just mapping data to pins and using the right codecs. There are a LOT of handshakes involved along the way (which is also the basis for HDCP which essentially all commercial streaming services utilize to some degree).
There ARE methods (that I have personally used) to take a DP->HDMI dongle and flash a super sketchy Chinese (the best source for sketchy tech) firmware to effectively cheat the handshakes. It isn’t true HDMI 2.1 but it provides VRR and “good enough for 2025” HDR at 4k/120Hz. But… I would wager money that is violating at least one law or another.
So expect a lot of those “This ini change fixes all of Windows 11. Just give money to my patreon for it” level fixes. And… idiots will believe it since you can use a dongle to already get like HDMI 2.05 or whatever with no extra effort. And there will likely be a LOT of super sketchy dongles on AliExpress that come pre-flashed that get people up to 2.09 (which is genuinely good enough for most people). But it is gonna be a cluster.
And that is why all of us with AMD NUCs already knew what a clusterfuck this was going to be.

Cable Matters sells plenty of different DP->HDMI 2.1 adapters that work with VRR. The main issue here is that you won’t get CEC if you use those.

I have one of these, but I don’t believe they work with HDMI 2.1 VRR (or at least I’ve never been able to get it to work).
With a LG B9, I have both G-Sync and HDMI 2.1 VRR support, but no FreeSync. I can get most of the HDMI 2.1 feature set working with a DP->HDMI 2.1 adapter, except for any form of VRR. That’s with a RX 9070, but similar situation on a 6800 XT previously.
