I’m 6-8 feet from a 65, depending on seating position and posture. It seems to be a pretty sweet spot for 4K (I have used the viewing distance calculators in the past, but not recent enough to remember the numbers). I do wear my glasses while watching TV too, so I see things pretty clearly.

With games that render at a native 4K at 60fps and an uncompressed signal, it is absolutely stunning. If I try to sit like 4 feet from the screen to get more immersion, then it starts to look more like a computer monitor rather than a razor sharp HDR picture just painted on the oled.

There is a lot of quality yet to be packed into 4K. As long as “TV in the living room” is a similar format to now, I don’t think 8K will benefit people. It will be interesting to see if all nice TVs just become 8K one day like with 4K now though.
