About these values

Browsers intentionally limit hardware identification for privacy. Values such as device memory, network type and platform may be approximate or unavailable.

Practical guide

How to read browser-reported device information

This page summarizes details that a web browser is allowed to expose, including screen dimensions, viewport size, pixel ratio, touch support and selected performance hints. It is useful for debugging display scaling and checking what a website can actually see about the current device.

For a more reliable result

Screen resolution and viewport are different: the viewport is the area available to the webpage, while the screen values describe the browser-reported display space.
Device pixel ratio helps explain why a high-DPI screen can render many physical pixels behind a smaller CSS layout.
CPU core and memory values, when exposed, are coarse browser hints rather than a complete hardware specification.
Privacy restrictions intentionally prevent websites from reading many serial numbers, exact model identifiers and low-level hardware details.

What this test cannot confirm

Treat the page as a browser-environment report, not as a replacement for the operating system’s hardware-information utility.
