Miracast allows you to wirelessly mirror your Windows screen to a TV or compatible display. However, after a Windows update, some users experience issues such as connection failures, black screens, or the “This device doesn’t support Miracast” error.
If Miracast stopped working after a Windows 10 update, follow the troubleshooting steps below.
Common Miracast Issues After Windows Update
After installing updates, you may notice:
- Unable to detect wireless display
- “Miracast not supported” message
- Screen flickering during connection
- Connection drops frequently
- No option to connect to wireless display
Updates sometimes change driver compatibility or network settings.
Fix 1: Check If Miracast Is Still Supported
First, confirm your system still supports Miracast.
- Press Windows + R
- Type:
dxdiag
- Press Enter
- Click Save All Information
- Open the saved file
- Search for Miracast
It should say Available. If it says not supported, the update may have affected drivers.
Fix 2: Update Graphics Drivers
Miracast depends heavily on graphics drivers.
- Press Windows + X
- Select Device Manager
- Expand Display adapters
- Right-click your GPU
- Select Update driver
Alternatively, download the latest drivers from:
- Intel website
- AMD website
- NVIDIA website
Restart your PC after updating.
Fix 3: Update Network Adapter Drivers
Miracast also requires Wi-Fi drivers.
- Open Device Manager
- Expand Network adapters
- Right-click your Wi-Fi adapter
- Click Update driver
Ensure your adapter supports Wi-Fi Direct.
Fix 4: Reinstall Wireless Display Feature
Sometimes the Wireless Display feature gets disabled.
- Open Settings
- Go to Apps
- Click Optional features
- Click Add a feature
- Search for Wireless Display
- Install it
Restart your computer.
Fix 5: Enable Miracast in Settings
To connect:
- Press Windows + K
- Select your wireless display
Or:
- Open Settings
- Go to System
- Click Display
- Select Connect to a wireless display
Ensure your TV or monitor supports Miracast.
Fix 6: Roll Back Windows Update
If Miracast stopped working immediately after an update:
- Open Settings
- Go to Update & Security
- Click Recovery
- Select Go back to the previous version
This may restore compatibility.
Fix 7: Check Firewall and Antivirus
Sometimes firewall settings block Miracast.
- Temporarily disable antivirus
- Allow Wireless Display through firewall
- Ensure private network profile is active
Use a secure Wi-Fi network.
Fix 8: Reset Network Settings
If connection issues persist:
- Open Settings
- Go to Network & Internet
- Click Status
- Select Network reset
- Restart your PC
This refreshes network configuration.
Ensure Both Devices Are Compatible
Miracast requires:
- Wi-Fi adapter supporting Wi-Fi Direct
- Graphics driver supporting WDDM 1.3 or higher
- Updated firmware on receiving device
If hardware does not meet requirements, Miracast will not function properly.
Final Thoughts
Miracast not working on Windows 10 after an update is usually caused by outdated drivers or disabled features. Updating graphics and network drivers, reinstalling Wireless Display, or rolling back problematic updates often resolves the issue.
If none of the solutions work, verify hardware compatibility or consider using a wired HDMI connection.
