Check your screen resolution, browser viewport, pixel ratio and other display information instantly.
Screen values are reported by your browser and operating system. Browser zoom, display scaling, multiple monitors and device settings can affect the values shown.
The Screen Resolution Checker is a browser-based tool that displays information about your current screen and browser window. It can show screen resolution, available display area, viewport dimensions, device pixel ratio, color depth and orientation without installing software.
Screen resolution describes the dimensions reported for the display, while the browser viewport is the visible area available to the web page. The viewport is usually smaller because browser controls, window size, zoom and operating-system interface elements can reduce the usable area.
Display scaling, browser reporting and device pixel ratio can affect the values exposed to websites. The tool shows the information available through your browser.
Device pixel ratio is the ratio between physical device pixels and CSS pixels reported by the browser. High-density displays often use a value greater than 1.
No. Standard browser APIs generally provide display dimensions and related properties, not the exact monitor model.
No special browser permission is normally required for the basic display information shown by this tool.
