Windows 11 makes it easy to duplicate your screen so the same content appears on both your computer monitor and an external display such as a TV, projector, or second monitor. Screen duplication is useful for presentations, watching movies on a larger display, teaching online classes, demonstrating software, or sharing your screen during meetings. Instead of extending your desktop across multiple displays, duplicate mode mirrors everything from your primary screen.
Whether you’re using an HDMI cable, DisplayPort, USB-C, Miracast wireless display, or a docking station, Windows 11 provides several ways to duplicate your display. If one method doesn’t work, another usually will.
In this guide, you’ll learn multiple ways to duplicate your screen in Windows 11, how to switch between display modes, and what to do if screen mirroring isn’t working.
What Is Screen Duplication in Windows 11?
Screen duplication, also called screen mirroring, displays identical content on two or more screens simultaneously. Whatever appears on your laptop or desktop monitor is also shown on the connected display.
This differs from Extend mode, where each display becomes part of a larger desktop, allowing different windows to remain open on separate screens.
Duplicate mode is commonly used for:
- Presentations
- Classroom teaching
- Video streaming on TVs
- Business meetings
- Software demonstrations
- Gaming on larger displays
- Training sessions
Windows 11 supports both wired and wireless display duplication.

Wait a few seconds until Windows detects the display.

Windows + P
