Screen Resolution Test

Read your display's browser-reported resolution, viewport size, and pixel density, then compare it visually against common reference resolutions.

The pixel grid below has fine lines every 10 CSS px and bold lines every 100 CSS px, so you can visually judge scaling and sharpness. Pick a preset to overlay a frame sized to that resolution.

Select a preset above to overlay a reference frame.

Note: this overlay is a rendered approximation — it is drawn in CSS pixels (target resolution ÷ your device pixel ratio) using your browser's reported DPR. It is not a true native-resolution test and cannot confirm your panel's actual physical pixel count.
