I have always been running DP, so no issues there. My RTX 2070 has DP 1.4Thos only supports 144hz over DP. Prettt sure you need DP 1.4 but you dont need hdmi 2.1 unless you want 120hz over hdmi.
I see Acer, Asus and Gigabyte all have a 4K/144Hz 43" VA with some form of freesync type deal. I am expecting these to be practically identical, but the Aorus seems to promise a bit more. As if that really means very much.
Here's the list! The difference I am seeing is really just the HDR rating?
