Frequently Asked Questions
What is a black screen online?
A black screen online is a free web tool that turns your entire display into a solid black background. You can use it directly in your browser without downloading any software.
Does a black screen save battery?
Yes — on OLED, AMOLED, and Super AMOLED displays, black pixels are turned completely off, consuming zero power. A full black screen can reduce screen power consumption by 40–60%.
How do I go full screen?
Click the "Full Screen" button in the control bar, or simply click anywhere on the screen display. Press Escape or click "Exit" to return to the normal view.
Can I use this on my phone?
Yes — the site works on all modern smartphones, tablets, and desktops. On mobile, tap the Full Screen button to enter full screen mode.
How do I change brightness?
Use the brightness slider in the control bar (the sun icon). Slide left to reduce brightness, right to increase. This works in addition to your system brightness.
Does this test for dead pixels?
Yes. Go full screen on a solid black screen to check for bright spots (stuck pixels). Use a white screen to check for dark spots (dead pixels).

Completely free. No registration, no download, no ads in fullscreen mode. Just open the site and use it instantly.
Can I use a custom color?
Yes — click the rainbow swatch (the last button in the color palette) to open a full color picker. Choose any hex color you want.
What is the black screen used for in photography?
Photographers use a black screen as a dark backdrop for product shots, to test lighting setups, and as a reference black for color calibration.
Why does my OLED screen look better on black?
OLED pixels emit their own light. To display black, OLED pixels turn completely off — making blacks perfectly dark with zero backlight bleed, unlike LCD screens.
