How to Set Your Primary Display in Windows 11 Extended Mode

If you use more than one monitor, you might notice your apps opening on the wrong screen. Setting a “primary” display fixes this. It tells Windows which monitor should hold your main taskbar and clock.

Why set a primary display?

Setting a primary display helps keep your workspace organized. It ensures your desktop icons and start menu appear exactly where you want them, making your computer easier to use.

What happens when you are done?

Once you finish, your chosen monitor will become your main workspace. The taskbar and system clock will move to that screen, and new apps will open there by default.

To start, open your Windows settings. You can press the Windows key + I on your keyboard, or click Start and select Settings.

Once in the Settings menu, click on System on the left side, then select Display on the right.

Windows will show you a map of your screens. Click the Identify button to see a number appear on each monitor so you know which is which.

Make sure the dropdown menu is set to Extend these displays.

To change your main screen, follow these steps:

1. Click on the rectangle representing the monitor you want to be your primary display.
2. Scroll down to the Multiple displays section.
3. Check the box that says Make this my main display.

Note: If the option to check the box is greyed out, that monitor is likely already set as your primary display. You may need to restart your computer for all your app icons to move to the correct screen.

Summary

Using multiple monitors is a great way to get more work done. By setting a primary display, you take control of where your windows and taskbar appear. If things don’t look right immediately after changing these settings, a quick restart of your computer usually clears up any display glitches.
