Why Use Our Display Detector?

Native Resolution & Class

See your screen native pixel resolution alongside the human-readable class, Full HD, QHD / 2K, 4K UHD, 5K, 8K UHD, UWQHD ultrawide, and so on. Combined with the device pixel ratio (DPR), the tool then labels the display class, Retina HiDPI, 4K HiDPI, etc, so you instantly know what visual quality the device is capable of.

Color Gamut & HDR

Beyond pixel count, the tool reports the color gamut your display covers, sRGB (standard web), Display P3 (wide color, used by recent iPhones, iPads, MacBooks, and OLED TVs), or Rec.2020 (ultra-wide, very rare). It then probes for HDR (high dynamic range) using the CSS dynamic-range media query, with a sensible fallback heuristic for older browsers.

Live Refresh Rate

Most display detectors hard-code 60 Hz because there is no direct browser API for refresh rate. This tool actually measures it, running for 700 ms via `requestAnimationFrame` to time individual frames, taking the median, then snapping to the nearest common rate (30, 48, 60, 75, 90, 120, 144, 165, 240 Hz). So 120 Hz iPad ProMotion, 144 Hz gaming monitors, and 90/120 Hz Android phones all read correctly.

100% Client-Side

Every value comes from `window.screen`, `navigator`, `window.matchMedia`, and `requestAnimationFrame`, read directly in your browser. There is no server call, no logging, no ad-tech fingerprint upload. Open DevTools and watch the Network tab while the tool runs, you will see exactly zero outbound requests carrying display data.

FAQ

Frequently Asked Questions

Common questions about display capabilities and how this tool reads them.

What is Device Pixel Ratio (DPR) and why does it matter?
DPR is the ratio of physical pixels to CSS pixels. A 1× display draws one screen pixel per CSS pixel. Apple Retina displays (and most modern phones) use 2×, 3×, or even 4×, meaning a "1px" CSS line is actually drawn with 2, 3, or 4 hardware pixels for a sharper result. DPR matters when you author images: serving a 1× JPG to a 2× display looks soft, so you typically ship 2× or 3× variants and let the browser pick the right one via `srcset`.
How is the refresh rate measured?
The tool runs `requestAnimationFrame` repeatedly for ~700ms, recording the timestamp of every frame. It then takes the median frame duration (less affected by occasional jank) and divides 1000 by that to get the rate in Hz. Finally it snaps the result to the nearest common rate (30 / 48 / 60 / 75 / 90 / 100 / 120 / 144 / 165 / 240) within a ±3 Hz tolerance. The browser tab must be visible and not throttled for the measurement to be accurate.
Why does the tool sometimes show a color gamut narrower than my real display?
The browser only reports the gamut it has been instructed to render in. Some browsers default to sRGB even on a P3-capable display until the page explicitly opts in (via the `color-gamut` CSS feature or a color-managed canvas). If you are sure your display is P3 or better but the tool reports sRGB, your browser is gating wide-color rendering, try the latest Safari or a Chromium-based browser with hardware acceleration enabled.
Is the User Agent string considered fingerprinting?
The tool only displays values your browser already exposes to every website you visit, there is no covert fingerprinting and nothing is uploaded. Modern browsers progressively redact the user-agent string (Client Hints) precisely to limit fingerprinting, so you may see slightly less detail in newer Chrome / Edge than you would have a few years ago. The Copy Report button writes everything to your clipboard locally; nothing is sent over the network.
