Practical Uses of a Full White Screen
While a black screen is great for saving power, a bright white screen turns your device into a versatile light source. It utilizes 100% of your display's brightness to provide clean, even illumination.
1. Soft Light for Video Calls (Webcam Lighting)
Poor lighting can make you look grainy in Zoom or Teams meetings. If you don't have a ring light, simply open this White Screen on a second monitor or tablet and face it towards you. It acts as a professional "softbox," creating a flattering light that removes shadows from your face.
2. Monitor Cleaning Helper
It is difficult to see dust, fingerprints, and smudges on a dark background. By switching your screen to pure white, these imperfections cast a shadow and become instantly visible. Use this mode to thoroughly clean your display.
3. Testing for Dead Pixels
A "dead pixel" that fails to light up will appear as a tiny black dot on a white background. This page is the standard tool for checking LCD and OLED panels for these manufacturing defects. If you see a dark spot, you may have a warranty claim.
