From what I understand 200% 4k is the same screen real estate as 1080p. It's a trade off I suppose. I would much prefer 1440p on a smaller monitor (like a 25") which offers pretty good DPI. I can read HN's text at 1:1 scaling from around 3 feet away and I wear glasses, 4 feet is doable too but it starts to get blurry. In my day to day I stand a little further than an arm's length away.
