About Dippi

Dippi estimates a display’s DPI and aspect ratio from its size and resolution, then indicates whether its pixel density is suited to LoDPI or HiDPI use. It also shows logical resolution and scaling information.

Use it to assess a monitor or laptop screen before buying, or to understand how a display may work with desktop scaling. Dippi is primarily designed for GNOME and Linux.

Strengths

Calculates display DPI and aspect ratio from size and resolution
Classifies density from very low DPI to ideal for HiDPI
Shows logical resolution and scaling factor

Limitations

Designed primarily for GNOME and Linux
