- The Miracast not supported by the graphics driver problem prevents you from projecting your screen.
- Miracast is a wireless technology allowing you to stream content from a device to a screen or projector.
- First, verify if the devices are compatible. This guide will show you how to fix Miracast if it's not supported.
- You also have to verify your connection. Sometimes it can be as easy as that.
So, you want to connect your device via wireless to a new display. But something goes wrong and you get an error message informing you that Miracast is not supported by your graphics drivers.
What could we ever do about this? Before we delve into the solutions, let’s take a few moments to talk about what Miracast really is.
Miracast, on simpler terms, works just exactly like a HDMI cable, but without the need to actually plug it in.
This feature enables you to mirror various device screens, such as tablets, laptops to displays like monitors, TVs or projectors without the use of an USB cable.
The possibilities are virtually limitless. So enough theory-crafting, and let’s get back to finding the solutions of how to fix Miracast not supported.
What can I do if Miracast is not supported by graphics drivers?
- Verify Miracast compatibility
- Set up Miracast
- Check your Wi-Fi connection
- Disable your VPN
- Reinstall your network drivers
1. Verify Miracast compatibility
1.1 Verify your network adapter
- Press Windows key + R to open up a Run dialog box.
- Type powershell in the field and press Enter.
- Type the following command and press Enter to verify if you have the right network adapter driver version:
Get-netadapter|select Name, ndisversion
- If the returned value that is being displayed is above 6.30, your machine is up and running to support Miracast in respects to network capabilities;
- Close the Powershell.
1.2 Verify your graphics card
- Press Windows key + R to open up a Run dialog box. In this run box you’ll type dxdiag and press Enter to open the DirectX Diagnostic page;
- Once the page is opened, expand the Display tab and look at the bottom of the Drivers column for the Driver Model. If the driver model isn’t showing WDDM 1.3 or higher, your system is not compatible with a Miracast connection.
Sometimes, the easiest way to fix a problem is by finding out if your machine can support Miracast in the first place.
2. Set up Miracast
- Turn on the selected device you wish to project to.
- Press Windows key + I and select Devices.
- In the Bluetooth & other devices section, click Add Bluetooth or other device.
- Click on Wireless display or dock.
- Click your display device to project your Windows 10 machine to it.
- You’re all set, enjoy.
3. Check your Wi-Fi connection
- Press Windows key + R to open up a Run box.
- Type ms-settings:network-wifi and press Enter to open the Network & internet Settings menu.
- Check that Wi-Fi is turned On.
Miracast uses Wi-Fi Direct, so the only thing to worry about is that your devices are connected to the same network.
4. Disable your VPN
Some third-party VPN solutions will regularly reject connections from Wi-Fi Direct. So it’s a good idea to disable the VPN’s in question to solve any connection issues.
Additionally, you may also disable your antivirus and firewall. Don’t forget to enable your security tools as soon as possible to protect your computer.
5. Reinstall your network drivers
- Press Windows key + R and type devmgmt.msc in the field, and press Enter.
- Click on the Network adapters menu, then right-click on your Wireless Network Adapter and then click on Uninstall Device.
- Restart your machine.
- On start-up Windows will reinstall your network drivers.
- You’re good to go.
If the error keeps showing up, then the best solution is to just uninstall and reinstall your network drivers.
In some instances you’re dealing with corrupted drivers or a faulty installation, so the best solution is to re-install them. You can also do that with specialized software for driver updates.
