What is the Black Screen?
A simple fullscreen black display. Useful for testing monitor color accuracy and dead pixels, as a plain backdrop for video calls or streaming overlays, as a calming visual, or just for fun.
How to use it
- Click Click to Fullscreen (or press F / Space) to fill your entire screen.
- Press Esc at any time to exit fullscreen.
Example
Turn the room lights off, open the black screen in fullscreen, and look at the panel from straight on and then at an angle. A pixel that stays lit is stuck; lighter patches near the edges or corners are backlight bleed. Both are easy to miss on normal content, so this is worth doing within a new monitor's return window.
Common Use Cases
- Spotting stuck (always-lit) pixels, backlight bleed, and IPS glow, which only show up against pure black in a dark room.
- Seeing dust, fingerprints, and smudges before cleaning your screen.
- Making a screen look switched off while the device stays awake — during a long download, a presentation break, or on stage.
- Keeping a dark room dark when a monitor has to stay on, e.g. while watching or sleeping.
FAQ
- Does this work on mobile? Yes, tap the fullscreen button on any phone or tablet browser.
- Will the color look exactly the same on every screen? Not necessarily — color rendering varies by display, brightness settings, and color profile.
- Does a black screen save battery? On OLED and AMOLED screens (most recent phones and some laptops) yes — black pixels are switched off and draw almost no power. On LCD screens the backlight stays on behind a black image, so the saving is minimal; lowering brightness does more.
- Will a black screen stop my computer from sleeping? No. It is just a webpage showing black. Your power and sleep settings still apply, so change those if the device needs to stay awake.
- How do I find dead pixels with a black screen? On black, look for pixels that stay lit (stuck pixels). Dead pixels, which stay dark, are easier to see on white or a bright color — our Dead Pixel Test cycles through several colors for exactly that.
