Finding a 4K UHD TV to game on with PC & Strix GTX 1080Ti 011g

[Leatherskull]

Hi Folks -
Am looking to buy a 65" high end 4K UHD TV to use for a PC monitor - web, gaming, TV, LAN, etc. OLED is not feasible because of potential burn-in. Samsung Q90R seems great but has no support for Nvidia gpus. TCL 65Q825 looks good but hardly any hands on experience yet as it has just begun to ship to USA. Asus 65" monitor just out of my league at $5.000.
I would be very grateful for feedback from other Strix 1980Ti 011g owners who use it with 65" TVs - with high end gaming in mind (FFXV, Assasin's Creed Origins, Star Citizen ...) I am having a problem finding such a TV that has VRR support for Nvidia cards.
