Popular uses for these screen tools
A white screen makes a soft, even light for video calls, photography fill light, tracing paper drawings or inspecting a laptop for dust and scratches.
Solid colour screens help spot dead or stuck pixels, check colour uniformity and backlight bleed on a new monitor or phone.
Green and blue screens work as small chroma key backdrops, and the prank screens are just good fun on a colleague's unattended laptop. Screensavers keep a spare display active and visually interesting when you are not using it.
