To stream your screen on Windows 11, you can choose from several methods depending on whether you want to project it to a local wireless display, broadcast it online, or share it in a video conference. The most common method for projecting your screen to a nearby display involves using Windows' built-in casting features.
Projecting to a Wireless Display (Casting)
Windows 11 offers a straightforward way to project your screen to a compatible wireless display, such as a smart TV, projector, or another PC. This feature primarily uses Miracast technology.
How to Cast Your Windows 11 Screen
Follow these simple steps to project your display:
- Prepare Your Display: Ensure your TV, projector, or other compatible display device is turned on and set to the correct input source (e.g., HDMI input that supports Miracast, or a dedicated "Screen Mirroring" mode).
- Activate Connect: On your Windows 11 PC, press the Windows logo key + K simultaneously. This will open the "Cast" flyout menu on the right side of your screen.
- Select Your Device: From the list of available devices, select the wireless display you wish to cast to. Your PC will attempt to connect.
- Follow On-Screen Instructions: You may be prompted to enter a PIN displayed on your TV, or to accept the connection on the receiving device. Follow any additional instructions that appear on either screen.
Once connected, your Windows 11 screen will be mirrored or extended to the wireless display.
Supported Wireless Display Technologies
Windows 11's built-in casting primarily relies on Miracast.
| Technology | Description | Compatibility |
|---|---|---|
| Miracast | A wireless standard that allows devices to project their screens to compatible displays without cables. | Supported by many modern smart TVs, wireless display adapters, and Windows 10/11 devices. |
Troubleshooting Tips for Casting
- Ensure Wi-Fi is On: Both your Windows 11 PC and the wireless display should be connected to the same Wi-Fi network (though Miracast can sometimes work peer-to-peer).
- Update Drivers: Make sure your Wi-Fi and graphics drivers on your Windows 11 PC are up to date.
- Check Device Compatibility: Verify that your display device explicitly supports Miracast.
- Restart Devices: A simple restart of both your PC and the display device can often resolve connection issues.
- Firewall Settings: Ensure your firewall isn't blocking the connection for the "Wireless Display" feature.
Streaming for Online Broadcasts
If "streaming your screen" means broadcasting your desktop live to an audience on platforms like Twitch, YouTube, or Facebook Gaming, you'll need dedicated streaming software.

Screen Sharing in Video Conferencing
For sharing your screen during online meetings or video calls, the functionality is typically built directly into the video conferencing application you are using.
Common Video Conferencing Platforms
- Microsoft Teams: Popular for business and education.
- Zoom: Widely used for various types of online meetings.
- Google Meet: Google's video conferencing solution, integrated with Google Workspace.
General Steps for Screen Sharing in Meetings

- Locate Share Button: Look for a "Share Screen," "Present Now," or similar icon (often an arrow pointing up or a monitor symbol) usually located at the bottom or top of the meeting interface.
- Choose What to Share:
- Entire Screen: Shares everything visible on your desktop, including notifications.
- Window: Shares only a specific application window, hiding other desktop content.
- Browser Tab: (Common in web-based apps like Google Meet) Shares a specific browser tab.
- Start Sharing: Click the share button to begin broadcasting your selected content to other participants in the meeting.
By understanding these different methods, you can effectively stream your screen on Windows 11 for various purposes, whether it's for casual viewing on a TV, professional online broadcasting, or collaborative video calls.
