Update: My question is indeed a duplicate of Scale < 100% on Windows 10 (I did search before posting, but hadn't found this question). Sadly, the answer there does not seem to work for recent builds of Windows 10. Thanks anyhow, @music2myear.
Original: Under Settings → System → Display, there's an option called “Scale and layout”: “Change the size of text, apps, and other items,” it says. It defaults to 100% (“Recommended”!), but offers 125%, 150%, and 175%. I suppose those are for visually-impaired people. Is there any way to make text, apps, and other items smaller?
I have two 27" 1920x1080 monitors (about 82 dpi). Windows's fonts are huge on this display. Now, I realize that these aren't the highest-resolution monitors available. But I bought them because I wanted to see more stuff, not because I wanted to see bigger stuff. The line spacing in Explorer, Settings, and other programs is large— like 20 pixels. I could easily live with half of that, thus allowing me to fit four times as much stuff on my desktop. Any help?
