- Device pixel ratio shows your display scaling factor.
- 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.
