I have installed Asus Tuf Gaming NVIDIA GTX 1660 super. I tried to changed refresh rate from advanced display settings but it shows max 85hz.Change your display refresh rate in Windows
For 165Hz, please install extra NVIDIA or AMD graphic card on desktop system.
For NVIDIA, please install GTX 10xx or latest.
For AMD, please install RX500 or latest.
Don't connected it on laptop if you want to 144Hz or latest.
ok out of curiosity as i am suspecting that the Cable it came with is defective and you connect it with a different cable EG the HDMI Cable to see what that one does and report back with the result? (to me its acting like the cable is not a DP 1.4a Cable like it should be but a DP 1.1 Cable)Yes. You right about all
