What do people use a white screen for?

As a soft light for photos and video, a bright surface to trace on, a way to inspect a display up close, or a plain backdrop instead of whatever was on the screen.

How do I make it full screen?

Press Open fullscreen, or Start and connect the TV or phone. On a computer, F11 usually goes fullscreen and hides the browser bars.

Does it stay on all night?

The page asks the screen to stay awake, but the TV or computer’s own sleep settings still apply. Turn those off for a long-running screen.

One color, edge to edge

A white screen is a soft light for photos and video, a surface to trace on, a quick way to check a display for dust and dead pixels, or simply a way to blank a screen. Open it fullscreen and the color fills the whole display, edge to edge.

The color is part of the link, so it opens the same on a TV, a phone or a laptop, and the page asks the screen to stay awake. Nothing is stored on our servers and no account is needed. A free link shows a small ownscreen.com at the bottom; a live screen shows the color alone. Black, pink, red, green, blue, yellow, gray and a warm white are one pick away, and the editor takes any color you like.

Put it on a TV

Make it above. The preview is exactly what the screen shows.
Open it on the screen. Press Open fullscreen on that device, or send yourself the link. For a TV with an account, open ownscreen.com/tv and enter its code on your phone.
Leave it running. It fits any screen size and asks the screen to stay on.
