It helps you check your display for dead pixels, color accuracy, backlight bleeding, text clarity, geometry, and motion issues.
No installation is required. The tool runs directly in your web browser without downloads.
Yes, the tests work on desktops, laptops, smartphones, and tablets as long as you have a modern browser.
Run the Dead Pixel Test to display solid backgrounds (red, green, blue, black, white) and look for stuck or non-changing pixels.
Backlight bleeding happens when light leaks from the screen edges, making dark areas appear brighter. Our Backlight Test helps detect it.
No, it only helps you detect problems. Hardware issues like dead pixels or bleeding require repair or replacement.
Yes, using full-screen mode ensures the most accurate results without distractions or scaling issues.
Yes, it supports all major browsers like Chrome, Firefox, Safari, Edge, and Opera. For best results, keep your browser updated.
