Complete Guide to Computer Screen Mirroring: Wireless Connection to Large Screens for Windows & Mac

In meeting presentations or teaching scenarios, computer screen mirroring is one of the most common needs. Mastering wireless screen mirroring methods allows you to break free from cable constraints entirely.

1. Screen Mirroring Method for Windows Computers

Windows 10/11 systems have a built-in wireless display function:

Step 1: Enable the Projection Function

  1. Click the Notification Center in the bottom-right corner of the taskbar.
  2. Select the “Project” or “Connect” option.
  3. The system will automatically search for available wireless displays.

Step 2: Select a Device

Choose your screen mirroring device (such as a TV or mirroring adapter) from the list of detected devices, then click “Connect.”

Step 3: Choose a Display Mode

After connection, you can select from two modes:
  • Duplicate: The large screen shows the same content as your computer screen.
  • Extend: The large screen acts as a second monitor, expanding your desktop space.

2. Screen Mirroring Method for Apple Mac Computers

Mac users can implement screen mirroring via AirPlay:

Step 1: Confirm Device Conditions

Ensure your Mac and Apple TV (or TV supporting AirPlay 2) are connected to the same network.

Step 2: Click the Mirroring Icon

In the menu bar at the top of the Mac screen, find and click the “Screen Mirroring” icon (shaped like a display monitor).

Step 3: Select a Device to Connect

Choose your TV device from the drop-down menu—screen mirroring will be completed immediately after selection.

Professional Recommendation

For more professional and stable needs, it is recommended to use a hardware screen mirroring adapter. Typically, you only need to plug a USB button into your computer to achieve one-click screen mirroring, and it offers better compatibility with different devices.
