  • The optimal viewing distance of a 65“ TV is somewhere between 1.98m and 2.69m for it to fill out 30-40° of our field of vision, as recommended by the Society of Motion Picture and Television Engineers (SMPTE), for an immersive „cinematic“ watching experience.

    My TV is about 2.5m away from my couch and I’m quite happy with the size, although, if price didn’t play a role, I‘d have gone with another size up (77“). Although I admit, it’s not the most practical size and it’s not for everyone. It does take up a lot of space.

    However with 42“ you’re definitely sacrificing quality. Or at least I would be at the 2.5m distance I sit from my TV. The vast majority of people (me included) could not discern any difference between a FullHD and a UHD image there. Our eyes simply do not have that resolution (measured at up to 94 pixels per degree). Even my 65“ at the aforementioned 2.5m distance has a higher resolution than my eyes.

    So >=65“ is the only normal size for a normal home, if one actually wants a home cinema and actually not sacrifice on quality, detail and immersion.

    I always found those thought-journey thingies somewhat pointless when teachers at school n such tried to do them with us. Of course they weren’t experts, though, so maybe someone who really knows what they’re doing could invoke something but realistically, probably not.

    On the other hand, dimming the lights, closing my eyes and the relative quietness of only one person calmly telling a kind of story, made me calm and sleepy regardless, so maybe the imaginary journey isn’t necessary anyways.

    This post probably isn’t about sex but about gender. Those are two very different albeit related concepts. Sure, biology is mostly binary (although not quite as black and white, if you’re looking at any other features than gamete types. Femininity and masculinity do not define themselves by gamete type), but psychology very much isn’t binary.
