I hope AMD fixed this on their side, maybe by implementing it in hardware. Does anyone have a source? I've only seen reports of HDMI 2.1b support not specifying "Windows-only". Fingers crossed.

There's nothing to fix, the problem is patents. A true fix would be getting rid of HDMI and only supporting DP.

That'd be fine by me, if I could also actually buy a good TV that supports DP.

On the other hand, I also think it's bullshit that I pay for HDMI through both my GPU & TV, and the HDMI forum still denies me that bought functionality.

I imagine they make convert boxes. Could output the DP to one and then input that to the TV. But I'm still running a 720p Emerson TV so I probably don't know what I'm talking about.

Doesn't even need a box, I bet there are even just cables. One side DP, other side HDMI. And even DP -> DVI-D! Just guessing though, cause my old DVI-D-only server monitor is hooked up to the DP-only PC by magic.

DisplayPort out to HDMI in is generally easy to adapt with a cheap passive adapter, but going the other way is a huge pain.

I tried aDP to HDMI cable from JSAUX from my Deck to my TV (yeah, I know the dock got HDMI, I just wanted to try). It didn't work at all.
