But I bought them because I wanted to see more stuff, not because I wanted to see bigger stuff. Now, I realize that these aren't the highest-resolution monitors available. Windows's fonts are huge on this display.

Is there any way to make text, apps, and other items smaller? I suppose those are for visually-impaired people.

Thanks anyhow, Settings → System → Display, there's an option called “Scale and layout”: “Change the size of text, apps, and other items,” it says. Sadly, the answer there does not seem to work for recent builds of Windows 10. Update: My question is indeed a duplicate of Scale < 100% on Windows 10 (I did search before posting, but hadn't found this question).
