Black Screen began with a simple, everyday problem: someone bought a new monitor and wanted a quick way to check it for dead pixels and backlight bleed without installing software or signing up for anything. The fastest fix was a web page that filled the whole screen with pure black. That single tool turned out to be useful to a lot more people than expected, so we kept building.
Today, black-screen.dev is a free collection of fullscreen screen tools that run entirely in your browser. There is nothing to download, no account to create, and no settings on your device ever change. You open a page, it does one thing well, and you close it when you are done.
What Black Screen Is
At its core, this is a set of single-purpose web tools that paint your display a solid color, run a relaxing screensaver, or simulate a familiar screen for a harmless prank. Everything works in any modern browser on Windows, macOS, Linux, Android, iOS, and most smart TVs.
The tools are grouped into a few simple categories:
- Color screens — pure black, white, red, green, blue, and more, for pixel testing, photography lighting, and chroma key work.
- Screensaver screens — calming options like the DVD bounce, Matrix, and quotes screensavers.
- Video and wallpaper screens — ambient backdrops such as rain, ocean, fireplace, and night sky.
- Prank and novelty screens — playful, clearly-for-fun simulations like fake update screens and the classic blue screen of death, meant only for harmless jokes among friends.
Why We Built It
Most "simple" tasks online are buried under pop-ups, sign-up walls, and downloads that ask for permissions they do not need. We wanted the opposite. A black screen should be one click away, load instantly, and never ask anything of you.
That principle still guides every page we add:
- One job per page. Each tool does a single thing clearly, so you always know what you are getting.
- No installs, no accounts. Everything runs as a plain web page in your browser.
- No tricks. We do not hide features behind paywalls or collect more than we need to keep the site running.
What You Can Do Here
People reach for these tools in more situations than you might expect. A few common ones:
- Test a new display for stuck pixels, dead pixels, and backlight bleed before the return window closes.
- Save battery on OLED and AMOLED phones and laptops, where black pixels switch off entirely.
- Clean a monitor or TV by making smudges and dust easy to spot against solid color.
- Set up lighting for photos and video, using white as a soft fill or black as negative fill.
- Focus by removing every distraction behind a single floating window.
- Have a little fun with novelty screens designed purely for harmless pranks.

Black Screen is built and maintained by a small independent team that cares about fast, honest web tools. We are not a large corporation, and we are not trying to become a social network. We read the messages people send us, fix the bugs they report, and add tools when there is a real reason to. Many of the languages and features on the site exist because users asked for them.
If you have an idea, a bug, or a question, a real person reads what comes in. You can always reach us at admin@black-screen.dev or through our Contact Us page.
