As the author says, that 150% is not that good for the quality of text fonts showed on screen. I've been using a Dell UP2715K (27", 5K) for a few years and I've always used it at 200% scaling as the piece suggests. The texts are crystal clear, it's almost like seeing not a screen, but a sticker: everything is so well defined and precise.

Maybe that's because my eyesight is not that good lately. Even considering that, I really can perceive a 150% scaling on a 4K monitor when I see it. It isn't that bad and sure you can work with that, but man, do try 5K at 200% and then tell me about it.

It's a real tragedy there are not more 5K displays. The Apple Studio Display is expensive and a little absurd with that webcam and the A13 chip, but at least you can enjoy that resolution. I wonder if display makers will consider this someday and stop selling so much gaming models and so little 'work' models.
