Screen resolution test
See the screen dimensions, viewport size, pixel ratio, and color depth your browser reports.
Browser-reported screen information
Reading the browser’s screen and viewport values…
These are values exposed by this browser. OS scaling, zoom, external displays, remote sessions, and browser privacy settings can affect them; they do not certify the panel’s native resolution or physical size.
These browser values can help with a layout or scaling issue. They do not confirm the panel’s native resolution. Use your operating system settings to see or change the selected display mode.
Screen size, viewport, and device pixel ratio
Screen size here means the CSS pixel values your browser reports. The viewport is the part of the page visible in the open window. Zoom, system scaling, an external display, or privacy settings can change the numbers.
Device pixel ratio (DPR) compares CSS pixels with device pixels the browser exposes. It is not a verified count of physical pixels. For a physical size estimate, use the monitor size calculator. To reduce entered pixel dimensions to a ratio, use the aspect ratio calculator.
When should I use this report?
Share these values when describing a responsive layout problem. If you need the selected output mode, check display settings and your model’s specifications. This page cannot measure the panel or certify native resolution.
Is this a screen resolution test image?
No image is needed. This online report reads browser values, including on a phone. It cannot inspect a test image, identify the panel’s full pixel matrix, or change the selected resolution.
