Online screen test

Free online screen test for every display.

Pixy checks the display signals your browser can observe, then runs full-screen patterns to help you inspect pixels, colour, uniformity, HDR, refresh rate, and motion smoothness.

What it checks

Resolution, device pixel ratio, colour depth, colour gamut, HDR support, approximate refresh rate, full-screen inspection panels, and browser frame timing.

How to use it

Open Pixy on the exact screen you want to inspect, press the test button, keep the tab active, and watch the full-screen panels for visible defects.

What stays private

The screen test runs in your browser. Pixy does not need signup, upload, camera access, install, or hardware permission.

Why Pixy is more useful than a plain colour page

Most screen test pages only show solid colours. Pixy combines those inspection panels with browser-observed capability signals, a readable score, suitability notes, and a clear explanation of what browsers cannot know.

Use this checklist while Pixy runs

  1. Clean the screen before judging dust-like marks.
  2. Set your operating system to the display mode you actually use.
  3. Keep brightness at a comfortable normal level, not maximum unless you are testing bleed.
  4. Watch the corners and edges during black, grey, and gradient panels.
  5. Treat the result as a fast screen profile, not a lab calibration certificate.

Questions people ask

Is Pixy free?

Yes. Pixy is a free browser-based screen test.

Can Pixy see dead pixels automatically?

No. Browsers cannot see your physical panel without a camera. Pixy gives you the inspection panels and you look for defects.

Can Pixy replace a hardware calibrator?

No. Pixy reports browser-observed signals and visual patterns. Hardware calibration is still needed for colour-critical work.
