alt Hacker NewsThe hardware is great, but the software is lacking. macOS only supports resolution-based scaling which makes anything but the default 200% pixel scaling mode look bad. For example, with a 27" 4K display many users will want to use 150% or 175% scaling to get enough real estate, but the image will look blurry because macOS renders at a higher resolution and then downscales to the 4K resolution of the screen.
Both Windows and Linux (Wayland) support scaling the UI itself, and with their support for sub-pixel anti-aliasing (that macOS also lacks) this makes text look a lot more crisp.

This is correct and also increasingly affecting me as my eyes age. I had to give my Studio Display to my wife because my eyes can't focus at a reasonable distance anymore, and if I moved back further the text was too small to read. I ran the 5K Studio Display at 4K scaled for a bit but it was noticeably blurry.
This would've been easily solved with non-integer scaling, if Apple had implemented that.
(I now use a combo of 4K TV 48" from ~1.5-2 metres back as well as a 4K 27" screen from 1 m away, depending on which room I want to work in. Angular resolution works out similarly (115 pixels per degree).)

4K pixels is not enough at 27" for Retina scaling.
Apple uses 5K panels in their 27" displays for this reason.
There are several very good 27" 5K monitors on the market now around $700 to $800. Not as cheap as the 4K monitors but you have to pay for the pixel density.
There are also driver boards that let you convert 27" 5K iMacs into external monitors. I don't recommend this lightly because it's not an easy mod but it's within reason for the motivated Hacker News audience.

I use a Mac with a monitor with these specs (a Dell of some kind, I don't know the model number off the top of my head), at 150% scaling, and it's not blurry at all.
Yeah this is correct, I don't know why you're being downvoted. The decisions Apple made when pivoting their software stack to high-DPI resulted in Macs requiring ultra-dense displays for optimal results - that's a limitation of macOS, not an indictment of less dense displays, which Windows and Linux accommodate much better.
I would love to see examples of this. I have a MBP and a 24" 4K Dell monitor connected via HDMI. I use all kinds of scaled resolutions and I've never noticed anything being jagged or blurry.
Meanwhile in Linux the scaling is generally good, but occasionally I'll run into some UI element that doesn't scale properly, or some application that has a tiny mouse cursor.
And then Windows has serious problems with old apps - blurry as hell with a high DPI display.
Subpixel antialiasing isn't something I miss on macOS because it seems pointless at these resolutions [0]. And I don't think it would work with OLED anyway because the subpixels are arranged differently than a typical conventional LCD.
[0] I remember being excited by ClearType on Windows back in the day, and I did notice a difference. But there's no way I'd be able to discern it on a high DPI display; the conventional antialiasing macOS does is enough.
