Thanks to Windows 11, you can save energy, extend a portable PC’s battery life, and lengthen your screen’s lifespan if you configure your monitor or screen to automatically turn off after a certain period of time. Here’s how to set it up.

First, launch the Settings app by pressing Windows+i on your keyboard. Or right-click the Start button and select “Settings” in the menu.

In Settings, select “System” in the sidebar, then click “Power & Battery.”

In Power and Battery options, click “Screen and Sleep” to expand the section if necessary.

Expand the "Screen and Sleep" section.

The “Screen and Sleep” menu will reveal two to four options, depending on the type of PC you have. If you’re on a battery-powered tablet PC or laptop, you’ll see four options. If you’re using a desktop PC, you’ll see only two options.

To set how long it takes for your screen to turn off (if your PC is inactive), click the drop-down menu beside “On battery power, turn my screen off after” and select a time period, such as “5 minutes.”

Similarly, use the drop-down menu labeled “When plugged in, turn my screen off after” to choose a screen turn-off time for when your computer is hooked to a steady power supply. If you never want the screen to turn off, select “Never.”

Using the drop-down menus, choose a time for when you want your Windows 11 PC to turn off its screen.

On this same page, you can also configure your PC to go to sleep after a certain time period as well, if you’d like. Sleeping is a special low-power state where your computer stops running tasks but can be resumed quickly when you need it.

When you’re done, close Settings. From now on, when your PC sits idle for the length of time you specified, your monitor or screen will turn off automatically. To turn it back on, wiggle your mouse, tap your screen, or tap a key like the space bar.

Also, If you’d like to keep your screen on but prevent burn-in on a CRT or Plasma display, you can set up a screen saver instead. Good luck!
