What Screen Testing Suite does

DisplayCheck is a browser-based screen testing suite that lets users diagnose common monitor issues without installing software. The tool produces fullscreen test patterns that reveal dead pixels, OLED burn-in, color gradient problems, refresh rate consistency, and motion ghosting. Each test runs locally in the browser and provides clear explanations of what to look for, delivering a practical assessment of display health and performance.

  • Some advanced measurements may be estimates rather than precise calibrations
  • Fullscreen patterns occupy the entire screen, requiring you to exit before using other apps
Questions

Screen Testing Suite FAQ

Do I need to install anything to use DisplayCheck?
No, all tests run directly in your browser with no download or installation required.
Can DisplayCheck detect every display problem?
It covers common issues like dead pixels, burn-in, color banding, and motion ghosting, but browser limitations mean some precise measurements may not be possible.
Will the test patterns affect my monitor long-term?
The tests use temporary fullscreen patterns; they do not permanently alter your display, but prolonged use of static patterns on OLED screens could contribute to burn-in, so limit exposure time.
Is DisplayCheck free to use?
Yes, the service is free online with no subscription or payment required to run the tests.
