Screen Information - Resolution, DPR, Viewport and Touch
View screen information reported by your browser: screen and viewport size, device pixel ratio, estimated resolution, color depth, orientation and touch support.
Quick answer
Screen information reports browser-readable viewport size, screen size, device pixel ratio, estimated resolution, color depth, orientation and touch support for the current display.
Method: ScreenTestKit generates the test surface in your browser. Results depend on visual inspection; the site does not read or diagnose physical panel hardware.
How to use this test
- Open the page on the exact monitor or device you want to inspect.
- Check browser zoom and operating-system scaling before comparing values.
- Refresh the information after moving the browser to another monitor or rotating the device.
- Treat estimated resolution as a browser calculation rather than a hardware specification.
What to watch for
- Viewport dimensions that change with window size and browser controls.
- Device pixel ratio changes caused by browser zoom or display scaling.
- Different values when a laptop uses an external monitor or dock.
- Touch support and orientation values reported by the current browser.
How to interpret results
Viewport differs
This is normal when the browser is windowed, zoomed or showing interface controls.
DPR above 1
The device maps more than one physical pixel to a CSS pixel, common on high-density screens.
Unexpected size
Check browser zoom, OS scaling, the active display and privacy restrictions.
Frequently asked questions
Is browser screen information exact?
No. Browser values can be affected by zoom, scaling, multiple displays and privacy protections.
Does this page identify my monitor model?
No. Browsers normally do not expose the physical monitor model to a web page.
