Article says: "At least on macOS, the size of apps & notifications is not adjustable. Toolbar symbols, Tab-bar in Chrome, native apps on MacOS are not scalable."
This is factually incorrect.
By not explaining that what scaling options were tried in the article, it strongly appears that the author did not try them.
By not explaining here on HN what was tried in more detail, it appears to be handwaving away the issue.
It's totally possible that a smaller screen is better for his productivity, but that's a minor argument compared to the incorrect assertion made in the article and here.
I had a problem with a cheap thunderbolt-to-HDMI adapter that only did 4K@30Hz. MacOS scaling options were very limited (full 4k, HiDPI 1080p or scaled 1080p) and nothing looked great.
I tried the 27" 4k monitor at work with a thunderbolt to display port cable and all scaling options were then available to me. I'm running 1440p equivalent which seems to be about right for 27".
I chose a 4k for resolution flexibility and sharper text for code. I can fit more code on a 27" 1440p vs a 24" 1080p and text is sharper.
The only productivity I've lost has been appreciating how good everything looks. Well, that and trying to read about why I was missing the scaling options.
Hopefully someone in your situation will find this and learn the cable matters.
