Why Should You Test Your Screen?
A dead pixel is a common issue where a tiny spot on your screen stays one color or remains black. By using our full-screen color test, you can easily spot these defects. This is especially helpful when buying a new laptop or smartphone.
How This Tool Works:
- Red, Green, Blue (RGB): Tests the primary sub-pixels of your display.
- White & Black: Perfect for checking backlight bleeding and dark spots.
- Yellow: Helps in checking general color balance and brightness.
For best results, clean your screen surface before starting the test to avoid mistaking dust for dead pixels.
