How to Cast Windows 11 to a Smart TV Wirelessly

Screen casting from Windows 11 to a Miracast-compatible smart TV or wireless monitor allows you to duplicate or extend your desktop without physical cables. Windows 11 includes native Miracast support, meaning you can connect in seconds using built-in keyboard shortcuts or system settings. This guide outlines the exact steps to connect your PC to your TV, choose the right display mode, and resolve common connection problems.

Step 1: Prepare Your Devices

1. Enable Wi-Fi on Windows 11: Miracast uses Wi-Fi Direct. Ensure Wi-Fi is turned on on your PC, even if it is connected to the internet via Ethernet.
2. Turn on the TV’s Screen Mirroring: Ensure your smart TV is powered on. Depending on the brand (such as Samsung, LG, Sony, or Roku), you may need to open a specific input or app named Screen Mirroring, Smart View, Screen Share, or AirPlay/Miracast.

Step 2: Connect Using the Windows 11 Cast Menu

The fastest way to connect is using the built-in Windows Cast shortcut:

1. Press Windows Key + K on your keyboard to open the Cast menu in the bottom-right corner of your screen. (Alternatively, open the Quick Settings panel by clicking the Network/Battery/Sound icons on the taskbar, then click the Cast tile.)
2. Wait for Windows 11 to scan for available displays.
3. Click the name of your smart TV or wireless display from the list.
4. If prompted on your TV, accept the incoming connection request or enter the PIN shown on the TV screen.

Step 3: Choose Your Projection Mode

Once connected, you can change how your screen appears on the TV:

1. Press Windows Key + P to open the Project menu.
2. Select your preferred display mode:
   • Duplicate: Shows the exact same screen on both your PC and the TV.
   • Extend: Uses the TV as a second monitor, expanding your desktop space.
   • Second screen only: Turns off your PC monitor and displays output solely on the TV.

How to Disconnect

When you are finished presenting:

1. Press Windows Key + K.
2. Click Disconnect next to your connected TV.

Troubleshooting Tips

• Display Not Detected: Ensure both the TV and the PC are on the same Wi-Fi network if required by your TV model, and restart the TV’s screen mirroring mode.
• Miracast Compatibility: To verify if your PC supports Miracast, press Windows Key + R, type dxdiag, press Enter, click Save All Information, and check the generated text file for the line Miracast: Available.
• Driver Updates: If connection fails repeatedly, update your graphics drivers and Wi-Fi network adapter drivers via Device Manager or Windows Update.
