About Full Black Screen Tool
Need to clean your monitor? A full black screen makes dust, smudges, and fingerprints highly visible. Just click the fullscreen button, wipe down your display safely, and press ESC when you're done. No need to turn off your computer or mess with power settings.
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.
