I’ve got a LCD 55" TV and a 14" laptop. Ok the couch, the TV screen looks to me about as big as the laptop screen on my belly/lap, and I’ve got perfect vision; on the laptop I can clearly see the difference between 4k and FULL HD, on the TV, not so much.

I think TV screens aren’t as good as PC ones, but also the TVs’ image processors turn the 1080p files into better images than what computers do.

I’ve had a Kobo Aura H2O for years and it’s great
