My Screen & Browser Info
Values update as you resize the window. The information is shown only here and sent nowhere.
Everything about your screen and browser
Support teams and developers often ask “What's your screen resolution?” or “Which browser are you using?”. This page shows the answers at a glance and copies them in one click: screen resolution, the size of the browser window (viewport), device pixel ratio, browser and OS versions, language, time zone and accessibility preferences.
What the numbers mean
- Screen resolution — the logical resolution reported by the operating system (after display scaling).
- Viewport — the area inside the browser window available to web pages; it changes as you resize.
- DPR — device pixel ratio: how many physical pixels make up one CSS pixel. A 4K monitor at 200% scaling shows 1920×1080 with DPR 2; phones are typically 2–3.
- Physical pixels — resolution × DPR, the actual pixel count of the display.
Also shown: color depth, orientation, dark mode and reduced-motion preferences, touch support, primary input type, cookies, online status, logical CPU cores, approximate memory and the full user-agent string. Nothing is sent anywhere — it's read from your browser and displayed on this page only.
Frequently asked questions
My monitor is 4K but it says 1920×1080.
With 200% display scaling, the logical resolution is 1920×1080 and DPR is 2. The physical pixels (3840×2160) are listed too.
My phone's resolution looks small.
Phones have a DPR of about 3, so the logical resolution is much smaller than the physical one.
Can I see my graphics card?
Browsers mostly hide it for privacy, so it isn't shown.
