Nvidia are soon to release a 65 inch 4k 144fps monitor with hdr and gsync..but wait, there's no current tech that can do that, right?
If it doesn't have HDMI 2.1, you can call it 98hz, if you want your colours to be shown properly and not crunched.
Like they do on the 27" HDR Gsync monitors above that refresh rate.
In the mean time, there is the 65NU8000 60hz but Freesync HDR TV at 1/4 the price of the Nvidia TV. (there is also 55" model, and curved ones)
And new 120hz TVs coming out next year, while all of them going to be much cheaper than the Nvidia TV because their market is normal households not those feeling "exclusive" cash cows.
