Windows can use multiple displays in several ways, extending or duplicating your primary monitor. You can even turn off your primary monitor. Here’s how to change secondary display settings with a simple keyboard shortcut.

Using the Windows + P “Project” Menu

To quickly change how Windows 10 and 11 handle multiple displays, press Windows + P.

A dark-gray menu titled “Project” will pop up on the right part of your screen this differs if the PC is running Windows 10 or 11 see images below

Windows 11

From here, you can use the mouse or cursor keys and Enter to choose the option you’d like. Here’s what the options do:

• PC screen only: This mode only shows video on the primary display, even if a second one is connected.
• Duplicate: This mode duplicates the video output from the primary display onto a second display, which can be ideal for presentations.
• Extend: This mode extends the desktop across as many displays as you have connected. It stitches them all into one large virtual desktop, and you can move windows between them.
• Second screen only: This mode only shows video on the second display, while the primary display remains blank and unused.
