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.




















I care about HDR (on Linux) way less than I do VRR in general.
Is that the “sketchy” firmware you’re referring to?
