Screen Resolution & System Info

See at a glance which screen resolution and hardware your device uses — resolution, refresh rate, pixel density, graphics card and more.

What is my screen resolution?

This tool shows your resolution in CSS pixels and physical pixels, the aspect ratio, the pixel density (device pixel ratio) and the colour depth — handy for picking wallpapers at the right size or checking output for presentations.

Refresh rate & system data

It also measures the actual refresh rate (Hz) and shows your environment: graphics card, number of CPU cores, available device memory and the maximum number of touch points. Everything is read locally and updated live.

Frequently asked questions

Why does the shown resolution differ from the native one?

The browser reports the logical resolution in CSS pixels. Multiplied by the pixel ratio (DPR) you get the physical resolution — both are shown.

How accurate is the Hz measurement?

The refresh rate is estimated from animation frames and is very close to the real value (e.g. 60, 120 or 144 Hz).
