Earlier quoted context omitted.
I needed an all-in-one solution for streaming (Netflix, Prime, Spotify, Jellyfin, ...) so I went with an Nvidia Shield Pro on the HDMI port. Any smart TV is a dumb TV for me. I'll make it "smart" myself, the old fashioned way, as you described. One downside of HDMI is max 60 FPS, so its limited for gaming and OKish for interactive (such as navigation through menu or simple browsing) yet should be adequate for any vie…
60fps is not a limitation of HDMI. I have an LG OLED that has HDMI 2.1, which can do 4k120fps (at least). Unfortunately current-gen GPUs only support HDMI 2.0, so I am limited to 1440p120fps or 4k60fps for the time being.
No VRR (Variable Refresh Rate) though, so I'm just waiting for new GPUs myself.
