How does the Screen Finder determine the best display?

The Screen Finder calculates visual acuity thresholds based on 20/20 human vision (1 arcminute resolving angle), comparing pixel density against viewing distance and typical OS scaling needs.

What viewing distance should I use?

Phones are typically viewed at 10–14 inches (25–35 cm), laptops at 18–24 inches (45–60 cm), desktop monitors at 20–30 inches (50–75 cm), and TVs at 6–10 feet (1.8–3 m).

Why does UI scaling matter for high PPI displays?

Displays with very high pixel density (like 4K on a 27-inch screen) make unscaled interface elements tiny. OS scaling (125%, 150%, or 200%) keeps text readable while utilizing physical pixels for crisp rendering.

At 108.8 PPI, this is widely considered the desktop productivity sweet spot. UI elements and text render comfortably at native 100% OS scaling without blurring. Individual pixels are subtly discernible only upon close inspection.
