What is PPI?
PPI (pixels per inch) is how many pixels fit in one inch of screen. More PPI means sharper text and finer detail at the same distance. It depends on both resolution and size: a 4K image stretched across a 32-inch monitor is less dense than 1440p on a 24-inch one.
The "pixels blend together" distance is where someone with typical 20/20 vision can no longer pick out individual pixels. Sitting closer than that, you may notice some softness or jagged edges.

Frequently asked questions
What is a good PPI for a monitor?
Around 90–110 PPI looks sharp at normal desk distance without needing Windows scaling. 140+ PPI looks very crisp but usually needs 125–150% scaling so text isn't tiny.
Is 1080p fine on a 27-inch monitor?
At about 82 PPI, most people notice softer text up close. 1440p is the usual pick at 27 inches.
How far should I sit from my monitor?
For a typical desk setup, about 1 to 1.5 times the screen's diagonal, adjusted so you can see the whole screen without moving your head much.
