About Full White Screen
A full white screen is the ultimate tool for finding dead pixels (which will appear as black dots) and checking for color uniformity or screen burn-in. Additionally, turning your phone or tablet into a bright white screen makes for an excellent emergency flashlight or a softbox for macro photography.
How to use the Fullscreen Tool
Click the "Fullscreen Preview" button above. Your browser will hide all UI elements and display the pure color. This is perfect for:
- Finding dead or stuck pixels on your monitor.
- Checking for backlight bleed on LCD panels.
- Using your screen as a makeshift light source or reading light.
- Cleaning your display (dust is easier to see on a solid color).
To exit, simply press the ESC key or tap the screen on mobile.
