Check my screen & resolution
Inspect screen resolution, available size, viewport, pixel ratio (DPI), color depth, orientation, and accessibility preferences (color scheme, reduced motion).
This display check reads `screen` and `window` metrics: resolution, avail size, inner/outer viewport, color depth, device pixel ratio, and orientation. Useful for responsive debugging, Retina/HDPI comparison, and understanding how pixel ratio affects web layout — CheckProxy.org.

FAQ — Screen, resolution & DPI
Questions about resolution, DPI, pixel ratio, and viewport in the browser.
Resolution is the screen’s width/height (`screen.width/height`). The inner viewport is the page content area after browser chrome — usually smaller than full screen.
Pixel ratio maps one CSS pixel to device pixels. A value of 2 on Retina displays means sharper images but often needs @2x assets — important for screen and UI checks.
Color depth is bits per color channel (often 24 or 30). Pixel depth may match or add buffer info — useful as a display quality hint.
On phones and tablets, rotation angle (0°, 90°, …) and portrait/landscape type help verify responsive layouts and media queries.
These are user/OS hints: dark or light theme and reduced animation. Sites can read them to adapt UI and accessibility.
