What to use a black screen for
OLED Display Test
Test your OLED or AMOLED display for true black levels and uniformity. On a perfect OLED panel, a black screen should show absolutely zero light emission.
Backlight Bleed Detection
LCD and LED monitors often show light leaking around the edges. A full black screen in a dark room reveals exactly where your backlight is bleeding through.
Dark Ambient Lighting
Use a black screen to darken a room for movie watching, sleeping, or creating a calm atmosphere without fully turning off your display.
Screen Burn-In Test
Check for image retention or burn-in on OLED displays. A solid black screen makes any ghosted images from previous content clearly visible.
