Screen Test & Dead Pixel Audit - FAQ
How to check for dead pixels on a laptop?
Use our full-screen display audit. By cycling through solid colors (Red, Green, Blue, White, and Black), you force every sub-pixel to activate.
What is Backlight Bleeding and how to test it?
Backlight bleed occurs when light leaks around the edges or corners of an LCD/IPS panel.
Do I need to install anything to test my screen?
No. The SpecInfo pixel test runs entirely in your web browser. It uses HTML5 Fullscreen API to safely render pure colors.
