White Screen Test is a website that lets you change your screen to a bright white one. With a white screen, it's easy to see if your display has any dead pixels. You can also use the light from the white screen to read or do other things in the dark.
If you want to see other colors, you can do that too. You can choose from full black screen, red screen, green screen, blue screen, etc, or even select any custom color as the full-screen background.
Here are the steps to turn off your laptop, computer, or mobile device's bright white screen.
Go to white-screen.site on the gadget you want a white screen on.
Click the box that is white on the page.
When you click, the screen on your device will be bright white and in full-screen view.
Press the Esc key to get your screen back to how it was before.
You can also add a text message to the screen if you want to.
