AMD & HDMI 2.1 (feddit.nl)

So, I bought an RX 7600 XT, when I was still using my 10 year old TV. Recently upgraded to an LG C4, reading the news about AMD support for HDMI 2.1 on Linux, I also went looking for a DP->HDMI adapter and found one that claims to even support VRR. After a week of getting random audio cuts, suspecting the adapter was at fault, I went pure HDMI...

To my surprise, I could run at 4K 120hz with VRR and HDR. Doesn't that require HDMI 2.1?

Thanks for the tip. It says YCbCr420. Anything I can do to improve that?

Nope, you're running into the dreaded AMD HDMI 2.1 limitation. The situation just sucks.

I would kindly ask the HDMI forum to point me in the direction of a DP to HDMI adapter that supports VRR or FreeSync. They seem so motivated to gain more funds from royalties, surely they know how to persuade me.

Fuck those guys. I really wish LG would support DP a bit more in their products.
