I have the adapter from Cable Matters I think and I’m fairly sure it supports VRR at 4:4:4 chroma subsampling. Tested it on a Hisense U8H. I stopped using the adapter though because on Windows it wouldn’t work with VRR, the screen would kind of go black when I moved the mouse. Not sure what it was.
I can confirm on this some time tomorrow
mfers raised the yearly price from 80 USD to 100 this year, and then they sent me an email that next year it’ll be 120! a 50% increase in two years, insane.
