The conflation was that 1920x1080 is a automatically poor clarity so that's why 4k is needed (at the same size). I.e. there is no resolution that is clear or unclear in and of itself, but that's how it is discussed.

One person talks about a laptop, another talks about their big coding desktop monitor, a third talks about a TV they use. None agree how much 1080p clarity makes sense for usage because the only thing quoted is resolution. This drives the assumption everyone is talking about the same sizes and viewing distances based on the resolution, which is almost never the case (before the conversation even gets to the age old debate of how much clarity is enough).

I'm sure if you ask the original commenter, they don't mean 1080p looks great for reading books at 34" just as much as GP wouldn't mean to compare screens of different sizes either.
