White Screen

What is White Screen?

White Screen is a free browser tool that fills your monitor, phone, or tablet with a fullscreen color display for cleaning, dead-pixel checks, display testing, and soft fill lighting. Open the page, pick white or another color, enter fullscreen, and adjust brightness and color temperature without installing an app or signing up. Advanced options include Keep Awake, OLED burn-in protection, a pixel grid overlay, quick presets such as Zoom Light and Clean Mode, and high-resolution white image downloads up to 8K. It is a practical screen utility rather than a productivity suite.

How to use White Screen?

1. Open whitescreen.im in your browser.
2. Choose white or another test color, then enter fullscreen (click or press F).
3. Adjust brightness, color temperature, Keep Awake, or OLED protection as needed.
4. Use the bright surface to clean, inspect pixels, light a subject, or download a still image.
