I'm running g-sync over hdmi in my 2019 samsung TV, using a RTX 3060 ti, I've got some flickering issues, but now I have solved them. The only thing missing is that this TV is hdmi 2.0 so it only goes to 48-60hz at 4k, but it goes to 48-120 at 1440p and seems to double the frame if it goes below the 48hzThe article says G-sync cannot be ran over HDMI but according to Nvidia/LG their G-sync compatibility is certified for LG 2019 TV onward which only have HDMI ports.
Lack of tearing overall and consistent frame representation without lagging feeling when FPS drop to 40..50 still is worth enough.Different question. Does Freesync/G-Sync add anything when running both FPS and Hz at or greater than 100? From my experience it adds nothing.
