SPECIFICATION GLOSSARY: MONITORS

Pixel density - what does it mean?

PPI is the number of pixels per inch. Higher pixel density usually means a finer pixel structure and sharper image at the same viewing distance.

IN PLAIN LANGUAGE

How to understand Pixel density?

Pixel density combines screen size and resolution into one useful measure of image fineness. Very high PPI may require operating-system scaling, so viewing distance and use case still matter.

WHEN COMPARING PRODUCTS

More is usually better

A higher value is usually beneficial, but it should not be the only buying criterion.

WHY IT MATTERS

PPI combines size and resolution into a useful sharpness indicator.

BUYING TIP

Consider viewing distance and OS scaling.

COMMON MISTAKE

Very high PPI may be unnecessary at a long viewing distance.
