Free Online White Screen Tool & Bright Light Source
Turn your display into a pure, blank white screen. This simple yet highly versatile utility is perfect for testing your monitor or laptop screen for dead, stuck, or broken pixels. By lighting up every subpixel at maximum brightness, irregularities stand out immediately.
Beyond screen diagnostics, a full white screen is an excellent soft light source. It can be used as a face light for video calls, a tracing light box for drawing, a reading light in a dark room, or even for product photography backdrops.
Our white screen tool is free, instant, and works on all devices including smartphones and tablets. Launch it in full screen to eliminate all browser UI elements and achieve maximum screen brightness.
Frequently Asked Questions
Learn how to set up and use the White Screen simulator on phones, TVs, laptops, and tablets.
How does a white screen help find dead pixels?
A pure white screen illuminates all red, green, and blue subpixels at 100% capacity. Any pixel that remains dark or showing a different color is dead or stuck.
Can I use this as a light for video calls?
Yes! Position your laptop or monitor in front of you, open the white screen in fullscreen, and it will cast a soft, flattering white glow on your face.
How do I exit the white screen?
Simply double-click the screen or press the Escape key (ESC) to exit the fullscreen mode.
