Everything You Need to Know

Common questions about screen utilities, color temperature, dead pixels, and monitor care.

What is a fullscreen blue screen used for?

A fullscreen blue screen (#0000FF) is used as an alternative chroma key background for subjects wearing green clothing, as a mood light, and for testing blue subpixels in LCD and OLED panels.

When should I choose blue screen over green screen for chroma key?

Blue screens are ideal when your subject has blonde hair (which can pick up green color spill), wears green clothing, or when working in dark night scenes.

How do I test blue subpixel health?

Open this pure blue screen in fullscreen and inspect for dark or non-illuminated pixels across the panel.
