I have a 1440P monitor with G-sync. This product supports G Sync with my setup. It is not rated by Nvidia so your mileage may vary. I was able to get the full resolution and FPS on my PC and M1 Mac mini. It doesn't come with cables, so make sure you use good quality cables and make sure they're as good as they can be for high frame rates. Input and output lengths add up, so 6ft t2 cable means you have 12ft and can run into artifacts at high frame rates.
