Key takeaways
- Black is #000000: every red, green and blue subpixel is off.
- On an OLED screen the pixels then give no light; on an LCD the backlight is still on.
- Look for points that stay bright, and for light leaking at the edges.

A pure black screen, without distractions.
Use #000000 to display a dark background or look for bright points during a manual screen inspection. How black looks depends on the panel and your surroundings. This tool does not diagnose a computer that will not start.
What can a black screen show you?
A black screen shows anything that should be dark but is not. On an OLED display each pixel makes its own light, so with #000000 the pixels are off and the panel looks fully dark. An LCD has a backlight behind the pixels that stays on, so in a dark room you may see a faint glow or brighter patches near the edges ("backlight bleed"). A single point that stays lit on black is easiest to spot here.
| Display | What #000000 does | What to look for |
|---|---|---|
| OLED | Pixels switched off | Points that stay lit |
| LCD | Pixels block the backlight | Edge glow, patches, lit points |

Questions, answered.
Does a black screen save battery?
On an OLED screen, black pixels are off, so a black screen can use less power than a bright one. On most LCDs the backlight stays on at the same level whatever the colour, so there is little or no saving.
Does a black screen turn off my display?
No. It displays black pixels while the device remains on. It is not a power switch or a repair tool.
How do I leave full screen?
Press Escape or move your mouse or touch the screen to reveal Exit. Press F to toggle full screen when you are not typing in a field.
Does it work on phones and tablets?
Yes. If your browser cannot open true full screen, the color fills the browser window instead. Browser bars may remain visible. You can use portrait or landscape orientation.
Can this change my device brightness?
No. Screen dimming darkens the displayed color only. Use your device’s brightness controls to adjust the physical display.
What does Keep screen awake do?
When supported and allowed, it asks your browser to keep the display on while this page is visible. The status shows whether the request is active, released or unavailable. Battery settings and system behavior may override it.
Can I download a 4K background?
Yes. Choose 4K UHD for a 3840 × 2160 image. Images are created on your device and contain the selected base color only, without the dimming effect.
