Yes Nvidia is finally supporting G-sync through HDMI with a driver update later this year for VRR TV's and monitors. Read Here https://www.nvidia.com/en-us/geforce/news/lg-gsync-compatible-hdmi-big-screen-gaming/

What are the chances of the samsung 2018-2019 VRR TV's working with this. I'm asking because i have the 2018 Q8FN which supports VRR. Would it be possible for you guys to release a firmware update to help make this work properly like LG is doing?
