I have used this TV with an AMD 6950 XT and have had no issues with getting Windows to give me the option to display at 120hz on any resolution. I bought a 4090 and its on its way. However I am currently using a 1060 which is only HDMI 2.0 since I sold the 6950 XT. Obviously I am unable to get 120hz with the current card. However the 4090 is HDMI 2.1 just like the 6950 XT. According to Rtings the Samsung Q80T is Gsync and freesync compatible. But I don't know if that is true or not. I am checking the Nvidia settings with the 1060 and I see no option for Gsync. Even if I don't get Gsync, will the 4090 give me VRR on the TV like the 6950 XT did?
