Screen Info
Useful when buying a screen protector or setting up scaling: these are the numbers that matter (physical pixels, device pixel ratio, color depth as the browser reports).
Values are read live from your browser — no data leaves your device.
How to use this test
Click Start — the test opens fullscreen over this page (nothing is installed, nothing leaves your browser). A control bar at the bottom of the screen lets you switch colors and exit with one tap — touch screens included; the Esc key and your browser's back button work too. Judge the screen in the lighting the test asks for; judging bleed or uniformity in a bright room defeats the test.
Frequently asked questions
Why does the resolution differ from my monitor spec?
OS scaling and browser zoom both report logical pixels. The "physical resolution × DPR" line gives you the true panel size.
