How do I black screen a Windows 11 laptop without turning it off?
Open the black screen tool on this page and click Full screen. Your laptop stays running in the background while the display shows pure black, and you can press Esc anytime to exit.
Does a black screen save battery on a laptop?
On laptops with OLED screens, black pixels turn off and use very little power. On standard LCD laptops, the backlight stays on, so battery savings are small.
Can I exit the black screen without a keyboard?
Yes. Double-clicking with a mouse or trackpad—or double-tapping on a touch-screen laptop—exits full screen immediately.
Will my PC go to sleep while the black screen is open?
If you tick Keep the screen on before going full screen, recent versions of Chrome, Edge, and Safari will keep your display awake.
