I sit 6' from my 77" lg cx oled. My philosophy is this: sit close enough to where you can start to see the individual pixels, then back up a little.

My wife has one too, so we got 2 77" LD OLED TVs in our living room. Might seem like overkill to some, but we're both avid gamers, so it's awesome to be able to play co-op games together on top-end rigs. Nothing will make a great TV sing like a good PC or video game console. HDR, 120hz, VRR, perfect black levels, etc. is so freaking awesome. Also, if any of you like to play old school games, or really anything at 60fps, try the BFI (black frame insertion) modes on the newer LG OLEDs. It mimics what CRTs do to achieve amazingly smooth motion. This is very different than smooth motion, which is of Satan and his spawn. HOWEVER, try smooth motion on games like Animal Crossing on Switch, and you might see it's use-case.

I've amassed a decent collection of 4K bluray titles. Probably over a hundred by now. Sure, you can stream a lot of 4K movies, but 1. it doesn't look as good 2. it doesn't sound as good 3. I don't want to be reliant on the whims of a streaming service/internet provider.

Insanely happy with both of our purchases. No other TV comes close for a wide variety of use-cases... except maybe if you want a TV in the sunroom, to which I say... just enjoy the sun and stop watching TV but in all seriousness, an OLED TV really shines in a dark room. If you're serious about a quality screen, you'll be serious about the room its in.

But I cringe every time I see a TV above the fireplace - terrible for eye/neck comfort. I suppose if all you do is watch the evening news it won't cause much strain... but regular consumption of mainstream news will give you much worse problems
