I Recently swapped from ultrawide to the LG CX 65". I was keen to try a BFGD setup so took the leap. Gsync works flawlessly hooked to my 2080Ti but fps is capped at 1440p 120hz due to Hdmi 2.0 on the GPU. Hopefully Ampere will bring 2.1 support and I can maximise the potential of the screen. The firmware for freesync premium may get used once the PS5 releases- but I've not seen it confirmed for either PS5 or SX yet despite them both having custom AMD Graphics.
