Screen Information Tool – Check Screen, Browser & Display Details Online

The Screen Information Tool on ZafScreen.com is a free browser-based utility that gives you useful information about your screen, browser viewport, pixel density, orientation, color depth, touch capability, and device type—all in one place.

No digging through system settings. Open the page and the information is right there.

The tool can display your Screen Resolution, Estimated Physical Pixels, Available Screen Size, Browser Viewport, Device Pixel Ratio, Aspect Ratio, Screen Orientation, Color Depth, Pixel Depth, Touch Support, Device Category, and Fullscreen Support.

That makes it useful for everyday users, web designers, developers, technicians, content creators, and anyone trying to understand how a website or display is being reported by the browser.

For example, your browser may report a screen size of 2048 × 1280 CSS pixels while the estimated physical pixel resolution is different. This can happen because of device pixel ratio, display scaling, browser zoom, and operating-system settings.

The Browser Viewport value is also useful because it shows the space currently available to a webpage—not necessarily the full size of your screen.

ZafScreen goes a little further with additional browser display details such as Inner Window, Outer Window, Visual Viewport, Orientation Angle, Screen Position, and Display Scale.

Need to update the values after resizing the browser or changing the display setup? Click Refresh Information.

Need to save the details somewhere? Use Copy Information to copy the available screen data for troubleshooting, development, or comparison.

Simple. Quick. And no installation required.

One thing to remember: the results are primarily browser-reported display information. They may differ from the specifications printed on your device box because operating-system scaling, browser zoom, display density, connected monitors, and privacy protections can influence what websites are allowed to detect.
