If Wireless Display is not working in Windows 11, the cause is usually a missing feature, a driver issue, or a problem with how the PC and display are paired. The good news is that most cases can be fixed without changing any hardware.
This guide walks through five practical fixes, starting with the most common causes and moving to less obvious settings that can block Miracast and wireless projection.
1. Make Sure Wireless Display Is Installed
Windows 11 does not always include Wireless Display by default. If the feature is missing, your PC may not detect wireless screens even though the hardware is fine.
- Open Settings and select Apps.
- Choose Optional features.
- Look for Wireless Display in the installed features list.
- If it is missing, select Add an optional feature and install Wireless Display.
- Restart projection or try connecting again after installation.
2. Check That Your PC Supports Miracast
Wireless Display in Windows 11 depends on Miracast support. If the laptop or desktop adapter does not support Miracast, Windows will not be able to project to a wireless display.
- Press Windows + R, type dxdiag, and press Enter.
- Wait for the tool to finish collecting information.
- Look for the Miracast entry in the report.
- If it says Available, your PC supports wireless projection.
- If it says Not supported by graphics driver or similar, the graphics or Wi-Fi driver may be the issue.
If Miracast is not available, the problem is often a driver limitation rather than a Windows setting.
3. Update or Reinstall the Display and Wi-Fi Drivers
Outdated, broken, or incompatible drivers are one of the most common reasons Wireless Display fails. This is especially likely after a Windows update or a graphics driver change.
- Open Device Manager.
- Expand Display adapters and Network adapters.
- Right-click your graphics adapter and choose Update driver.
- Right-click your Wi-Fi adapter and do the same.
- If the problem continues, uninstall the adapter and restart Windows so it can reinstall the driver automatically.
4. Verify the Wireless Display and Target Device Settings
Sometimes the Windows PC is fine, but the receiving display is not ready to accept a connection. Smart TVs, wireless adapters, and casting devices often need the right input mode or screen-mirroring setting enabled.
- Make sure the TV or wireless display is turned on and set to the correct input or casting mode.
- Check that screen mirroring, Miracast, or wireless display is enabled on the receiving device.
- Remove old or duplicate pairings from the display device if it has a device list.
- Bring the PC and display closer together to rule out weak wireless signal or interference.
- If the display supports both 2.4 GHz and 5 GHz, try the other band if available.
5. Reset the Connection and Clear Stuck Pairing Data
If Windows remembers a bad connection state, the pairing can get stuck and keep failing until the saved connection is removed.
- Open Settings and go to Bluetooth & devices.
- Find the wireless display or cast device if it is listed and remove it.
- Open Action Center or Quick Settings and try Project again.
- Choose Duplicate, Extend, or Second screen only, depending on how you want to connect.
- If the device still fails, remove it from the receiving display's saved devices list and pair it again from scratch.
When Wireless Display Still Won't Work
If none of the fixes help, the issue is usually one of three things: the hardware does not support Miracast properly, a driver is incompatible with Windows 11, or the receiving display does not support the connection method you are trying to use.
- Check the PC manufacturer support page for Windows 11-compatible graphics and Wi-Fi drivers.
- Try a different wireless display, TV, or Miracast adapter to isolate the problem.
- Use an HDMI cable temporarily to confirm the PC can output video normally.
- If the PC is managed by work or school policies, projection features may be restricted.
What to Try First
If you want the fastest path, check the optional Wireless Display feature first, then confirm Miracast support with dxdiag, and update the graphics and Wi-Fi drivers. Those three steps solve most Windows 11 wireless display problems.
