What is Black Screen?
Black Screen is a simple, ad-free web tool that displays a fullscreen black background. It's ideal for turning your screen dark without powering it off, simulating sleep mode, saving energy on OLED displays, or using it as a distraction-free second monitor background. You can also download pure black backgrounds in various resolutions for offline use.
How to Use Black Screen
- Click anywhere on the black screen or the fullscreen icon to enter fullscreen mode.
- Click again or press Esc to exit fullscreen.
- Select a resolution or enter custom dimensions and click "Download" to save a black background image.
Why Use Black Screen?
Darken a Second Monitor
Easily turn your second monitor dark without shutting it down, perfect for focused single-screen tasks or nighttime use.
Simulate Sleep Mode
Use a black screen to make your monitor appear off while background tasks continue to run, such as downloads or renderings.
Distraction-Free Studying
When using dual screens, you can keep one black to minimize visual distractions while focusing on studying or reading.
Save Battery on OLED Screens
Black pixels consume significantly less power on OLED displays. Using a black screen helps conserve energy and extend battery life.
Use as a Background
Use the fullscreen black background for clean visuals during presentations, screen recordings, or as a neutral backdrop in video calls.
Reduce Eye Strain
A black screen emits less light, making it suitable for low-light environments or late-night computer use to reduce eye fatigue.
Sleep Aid
Use a black screen in your room to dim light sources from your monitor, helping create a darker environment for better sleep.
Monitor Pixel Testing
Displaying a solid black screen allows you to check for glowing pixels or light bleed issues on LCD or OLED panels.
