How to Fix the Your Device Doesn’t Support Miracast Error and Get Wireless Screen‑Casting Working

If you’ve ever tried to wirelessly mirror your screen to a TV or monitor and seen the message “Your device doesn’t support Miracast, so it can’t project wirelessly”, you know how frustrating it can be. This error usually appears when your hardware isn’t compatible, your drivers are outdated, or certain settings need adjustment. The good news is that most of the time, this issue is fixable with a few straightforward steps.

Quick Answers: Why This Happens

What causes the “device doesn’t support Miracast” error?

Hardware incompatibility: Your graphics card or Wi-Fi adapter may not support the required technology (WDDM 1.3 for graphics, NDIS 6.30 for Wi-Fi).
Outdated drivers: Your network adapter or graphics drivers may be too old to support Miracast properly.
Wi-Fi disabled: Miracast requires Wi-Fi to be turned on—even if you’re using an Ethernet connection.
Missing Windows features: The Wireless Display feature may not be installed on your PC.
VPN or firewall interference: Third-party security software can block the connection.
Wrong wireless mode: Your adapter may be locked to 5 GHz only, which can cause compatibility issues.

What Is Miracast and How Does It Work?

Miracast is essentially a wireless HDMI cable. It lets you mirror your PC, phone, or tablet screen to a TV, monitor, or projector without any physical cables. Unlike Chromecast or AirPlay, which stream through the internet, Miracast creates a direct peer-to-peer connection between devices using Wi-Fi Direct.

Miracast has been around since 2012 and is built into Windows 8.1 and later, as well as many Android devices (Android 4.2+). That said, just because your operating system supports it doesn’t mean your hardware does—and that’s usually where the problem starts.

Check If Your Device Actually Supports Miracast

Before trying any fixes, you need to confirm whether your device can even use Miracast. Two components must work together: your graphics card and your Wi-Fi adapter.

Check Your Graphics Driver

Press Win + R, type dxdiag, and hit Enter.
Click Save All Information and save the file somewhere easy to find.
Open the saved text file in Notepad.
Search for Miracast under System Information. If it says “Available” or “Available, with HDCP”, your graphics support it.
Also check the Driver Model under Display Devices—it should be WDDM 1.3 or higher.

Check Your Network Adapter

Press Win + X and select Windows PowerShell (Admin).
Type this command and press Enter:

Get-netadapter | select Name, ndisversion

Look at the NdisVersion number. It needs to be 6.30 or higher for Miracast to work.

If either of these checks fails, your device doesn’t support Miracast natively. You’ll need to either update your drivers or use a Miracast adapter (like the Microsoft Wireless Display Adapter) to add the functionality.

Fixes You Can Try

1. Make Sure Wi-Fi Is Enabled on Both Devices

Miracast uses Wi-Fi Direct, which means Wi-Fi must be turned on—even if your PC is connected via Ethernet.

On Windows 10:

Press Win + R, type ms-settings:network-wifi, and press Enter.
Toggle Wi-Fi to On if it’s off.

On Windows 11:

Press Win + I to open Settings.
Go to Network & internet → Wi-Fi.
Make sure the Wi-Fi toggle is set to On.

Also check that Wi-Fi is enabled on the device you’re trying to connect to (TV, monitor, or another PC).

2. Install the Wireless Display Feature

Windows may not have the Wireless Display feature installed by default, especially on fresh installs or N editions.

Type optional features in the Windows search bar and press Enter.
Click Add a feature (Windows 10) or View features (Windows 11).
Search for Wireless Display and check the box next to it.
Click Install and wait for the process to complete.
After installation, type project in the search bar and click Projection settings.
Set the dropdown under “Some Windows and Android devices can project to this PC when you allow them to” to Available everywhere.

3. Update or Reinstall Your Wireless Network Adapter Driver

Outdated or corrupted network drivers are one of the most common causes of this error.

To update the driver:

Press Win + R, type devmgmt.msc, and press Enter.
Expand Network adapters.
Right-click your wireless adapter and select Update driver.
Choose Search automatically for drivers.

To reinstall the driver:

Follow the same steps above, but select Uninstall device instead.
Check the box for Delete the driver software for this device.
Click Uninstall, then restart your PC.
Windows will automatically reinstall the driver when your computer starts back up.

If Windows doesn’t find the latest driver, visit your PC or network adapter manufacturer’s website to download it directly.

4. Change Wireless Mode to Dual Band

If your wireless adapter is set to 5 GHz only or a specific 802.11 mode, it may not work with Miracast.

Right-click the Start button and select Device Manager.
Expand Network adapters.
Right-click your wireless adapter and select Properties.
Go to the Advanced tab.
Look for Wireless Mode Selection or 802.11 a/b/g Wireless Mode.
In the Value dropdown, select Auto or Dual Band 802.11 a/b/g.
Click OK and restart your computer.

5. Disable VPN or Third-Party Firewall Software

VPN clients and certain firewall applications can identify Wi-Fi Direct as a security risk and block the connection.

Temporarily disable any active VPN connections.
If you’re using third-party firewall software (not Windows Defender), disable it temporarily to test.
Try connecting to Miracast again.

If this fixes the issue, you can add the Wireless Display feature to your firewall’s allowed apps list instead of keeping it disabled.

6. Update Your Graphics Driver

Your graphics card needs to support hardware-accelerated screen mirroring for Miracast to function.

Visit your graphics card manufacturer’s website:
- NVIDIA: nvidia.com/drivers
- AMD: amd.com/support
- Intel: intel.com/support
Download and install the latest driver for your specific GPU model.
Restart your PC after installation.

7. Enable Integrated Graphics in BIOS (Advanced)

If you have a dedicated graphics card (like NVIDIA or AMD) that doesn’t support Miracast, but your CPU has integrated graphics (like Intel HD Graphics), you can enable the integrated GPU in your BIOS.

Restart your computer.
As soon as the manufacturer logo appears, press the BIOS key repeatedly (usually F2, Del, Esc, or F10).
Navigate to Advanced, Chipset, or Configuration (varies by motherboard).
Look for Integrated Graphics, iGPU, or Internal Graphics.
Set it to Enabled or Auto.
Press F10 to save and exit.

What NOT to Do

Don’t assume your device supports Miracast just because it’s running Windows 10 or 11—hardware matters more than the OS version.
Don’t rely solely on Windows Update for drivers—manufacturer websites often have newer versions.
Don’t keep VPN or firewall software running while testing Miracast—they can silently block the connection.
Don’t use a Miracast dongle if your graphics card doesn’t support hardware mirroring—it won’t work even with the adapter.

When to Contact Support

If you’ve tried all the fixes above and still see the error after 24-48 hours, it’s likely a hardware limitation rather than a software issue. At that point, consider:

Using an alternative like Chromecast, AirPlay, or a physical HDMI cable.
Upgrading your Wi-Fi adapter to one that supports Wi-Fi Direct.
Contacting your PC manufacturer’s support team to confirm Miracast compatibility for your specific model.

Conclusion

The “device doesn’t support Miracast” error is annoying but fixable. Start by checking if your hardware actually supports Miracast using the DxDiag tool and PowerShell commands. If it does, try updating your network and graphics drivers, enabling Wi-Fi on both devices, and installing the Wireless Display feature. Most users find that reinstalling the wireless network adapter driver solves the problem when nothing else works. If your hardware simply doesn’t support it, a Miracast adapter or alternative streaming method like Chromecast can get you back up and running.
