What is a White Screen Used For?
A solid white screen is a surprisingly useful tool.
🔍
Dead Pixel Detection
A solid white screen makes dead or stuck pixels visible. Display white full screen and inspect your monitor closely for any dark spots.
💡
Light Box / Light Table
Use your device as a light box for tracing, viewing negatives, inspecting slides, or checking transparencies.
📸
Photography Lighting
A white screen acts as a soft fill light for product photography, selfies, or video calls. It diffuses light evenly across your face or subject.
🧹
Dust Detection
Display a white screen to spot dust particles on your screen or keyboard. The bright background makes even tiny specks visible.
