How Does the Screen Resolution Checker Work?

  1. The tool reads your screen properties using the browser's Screen API.
  2. It detects your native resolution, available area, and viewport size.
  3. Device pixel ratio shows your display scaling factor.
  4. All information updates in real time if you resize your window or change displays.

Frequently Asked Questions

What is screen resolution?
Screen resolution refers to the number of pixels displayed on your screen, expressed as width x height (e.g., 1920x1080). Higher resolutions display more detail and sharper images.
What is device pixel ratio?
Device pixel ratio (DPR) is the ratio between physical pixels and CSS pixels. A DPR of 2 means each CSS pixel is rendered using 4 physical pixels (2x2), resulting in sharper text and images on high-DPI displays.
Why is my available screen size smaller than my resolution?
The available screen size excludes areas occupied by your operating system's taskbar, dock, or menu bar. It represents the space actually available for application windows.
Is my data sent anywhere?
No. All detection happens locally in your browser. No screen information is transmitted to any server.
