Black Screen

BlackScreen.VIP does exactly what the name says. Click and the browser tab fills the whole display with pure black, rendered as an exact RGB 0,0,0 canvas rather than a dark video. That's useful in more situations than it sounds. On OLED and AMOLED panels, true black switches pixels off. On a multi-monitor desk, a black window on the screen you aren't using cuts glare without rearranging your setup.

The same page switches to white, red, green and blue, plus yellow, orange, pink and purple. Cycling through those is the standard way to spot a dead subpixel, which stays dark on white, or a stuck one, which stays lit on black.

There's also a download option. Pick PNG, JPG or WEBP and a size, from HD at 1920 by 1080 through 2K, 4K and 5K up to 8K at 7680 by 4320, or mobile, square and custom dimensions, and you get a solid-color image. Designers and video editors can use it as a backdrop or mask without opening an image editor.

An all-tools page groups the other screens: color screens, sound and timers, lighting, screensavers, prank screens, meeting screens and fake update screens. Everything runs in the browser with no signup or upload. The privacy policy says the only data involved is an optional feedback form and an optional analytics setup, and that nothing you view or type on the screen leaves the page.
