The Black Screen tool displays a pure #000000 black screen directly in the browser and can be opened fullscreen for quick, distraction-free viewing.
What can you use a black screen for?
- checking displays in dark conditions
- spotting bright/stuck pixels and other illuminated irregularities
- checking LCD displays for visible backlight bleed or uneven illumination in dark conditions
- viewing how a display handles pure black
- providing a distraction-free dark background
- reducing emitted light compared with displaying a bright page
A black screen can be useful for spotting display issues, but it is not a professional calibration tool. Switching between White, Black, Red, Green and Blue can make different pixel and display defects easier to notice.
How to use the Black Screen
- Choose Black or another screen color.
- Click OPEN FULLSCREEN.
- Exit fullscreen normally when finished.
