How To Set up Miracast And Troubleshoot Its Problems In Windows 10

Miracast enables certified (Miracast-certified) devices such as laptops, smartphones, and tablets to communicate with TVs, monitors, and projectors. Its main purpose is to replace cables and wires from the device to display. It can be thought of as an 'HDMI over Wi-Fi' tool. Miracast allows users to broadcast photos, music, videos and other media from mobile devices and computers to larger screens (thus, it allows you to see your device's screen content on a bigger screen).

Miracast is a similar technology to AirPlay and Chromecast, however, these technologies are somewhat different. Miracast technology is built upon Wi-Fi Direct, which allows two devices to form a direct P2P (peer-to-peer) wireless connection and discover each other without a wireless router. It creates its own network on which paired devices can share data. As mentioned, Miracast is rather like an HDMI connection without physical cables that allows users to pair devices.

Later Android smartphones and Windows computers with Intel chips have access to Miracast - if you have a system that is a few years old, you will probably have access to it. Today, this technology is often built-in - most Smart TVs, Amazon Fire TV, Android TV, Roku and other devices support Miracast. There are many Miracast receivers, however, not all work properly, if at all.

To use Miracast, you need both devices to support it. To broadcast to the screen of a device, chipset, operating system, and driver support is needed. For Windows users, you must have Windows 8.1 or Windows 10. Older versions need third-party apps to support Miracast.

In the guide below, we show how to set up Miracast for Windows 10 users. Also, how to troubleshoot the most common problems relating to this technology.

How To Set Up Miracast

If you have a TV or other device that supports Miracast, then simply turn it on. If your display device does not have the built-in Miracast support, then you need to plug a Miracast adapter (such as Microsoft Wireless Display Adapter) into your device.

In Windows 10, the screen mirroring feature can be found in Action Center among other Quick settings. Click the Notification area button on the Taskbar (it is placed near the date and time) and click the "Connect" button. If you do not see the "Connect" button, click "Expand" to view more settings.

A list of available Miracast devices will appear. Click the device name you wish to connect to and the connection process will begin. You may need to enter a PIN to verify that a connection you are trying to establish is secure, or simply to complete the connection on your display device. You can also change the projection mode by choosing between monitor extensions, mirroring, and disabling primary PC display. If you want to mirror/broadcast only the primary screen, select the "Second-Screen Only" option.

If there are no available devices displayed, you might want to add a device using Windows settings. Type "bluetooth" in Search and click the "Bluetooth and other devices settings" option.

Update Display And Network Adapter's Driver

If Miracast is not working, update your drivers. Device driver is software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly. To update Display adapter and Network adapter driver, use Device Manager. To open Device Manager, right-click the Start button and select the "Device Manager" result from the contextual menu, or type "device manager" in Search and click the "Device Manager" result.

update display and network adapter driver step 1

In Device Manager, you will see a list of devices connected to your computer. Find the "Display adapters" category and expand it, right click your display adapter, and select "Update driver" from the contextual menu.

update display and network adapter driver step 2

You will be asked if you want to search for an updated driver software automatically or to browse your computer for driver software. If you select the first option, Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, you must locate and install drivers manually. Using this option requires having previously downloaded a driver on your computer or USB flash drive. We recommend that you select the first option - select it and follow the instructions. If first option does not solve the problem, download the latest drivers from the manufacturer's website.

update display and network adapter driver step 3

Once the display adapter is up-to-date, find the "Network adapters" category in the Device Manager's list and repeat the steps. See if this solves the problem and Miracast is now working without problems.

Snappy Driver Installer (SDI) is a powerful free driver updater tool for Windows that can store its entire collection of drivers offline. Having offline drivers gives Snappy Driver Installer the ability to have access to fast driver updates, even if there is no active Internet connection on your computer. Snappy Driver works with both 32-bit and 64-bit versions of Windows 10, Windows 8, Windows 7, Windows Vista, and also works with Windows XP. Drivers are downloaded through Snappy Driver Installer in 'driverpacks', which are simply collections (packs) of drivers for various hardware such as sound devices, video cards, network adapters, etc. It can also show duplicate drivers and invalid drivers. It separates the updates that require you to restart your computer so that they are easier to distinguish. You can download Snappy Driver Installer from here.

Check WLAN AutoConfig Service

Windows Services (also know as services.msc) are used to modify how Windows services run on your system. These services are responsible for running available programs and managing many system settings and resources. You can modify a service's settings for security, troubleshooting, and performance-related reasons. In this case, you need to check if the WLAN AutoConfig service is running and if it is a startup type set to Automatic. WLAN AutoConfig service provides the logic required to configure, discover, connect to, and disconnect from a wireless local area network. It also contains the logic to turn your computer into a software access point that other devices or computers can connect to your computer wirelessly using a WLAN adapter that can support this. To check if the WLAN AutoConfig service is running and it is a startup type is set to automatic, open the Run dialog box. Press Windows (Win) key + R, or simply right-click Start and select "Run" from the contextual menu. In the Run dialog box, type "services.msc" and press Enter or click "OK".

check WLAN autoconfig service step 1

You will see a list of Windows services, find WLAN AutoConfig and right-click it, select "Properties" from the contextual menu.

check WLAN autoconfig service step 2

In the WLAN AutoConfig Properties window, find "Startup type" and set it to "Automatic". Ensure that "Service status" is running. If it is not, then press the "Start" button to start it. Click "Apply" and exit Windows Services. Try to restart your computer and see if Miracast is now working.

Restore Your System Using Restore Points

If Miracast stopped working after you installed software or made other changes that could affect it, we recommend you use System Restore. A restore point is a collection of important system files stored by System Restore on a given date and time. System Restore reverts everything to a saved restore point, but first, you must have one recorded. If a restore point does not exist on your computer, System Restore has nothing to revert to. To use this tool, you must have created restore points. With a created restore point, this feature will bring your system back to the previous working state, without affecting your files and data. If you have any system restore points that were created before you started experiencing problems with Miracast, you might be able to fix the problem by performing a System Restore. To restore your system, launch Run by pressing the Windows Key + R and type "rstrui.exe". In the Run dialog box, press Enter or click "OK".

restore your system using restore points step 1

In the System Restore window, click "Next".

If there are restore points created, you will see a list of them. Mark the "Show more restore points" checkbox, which should display more restore points. Select the most appropriate restore point (depending on the time created, etc.) and click "Next".

restore your system using restore points step 3

Confirm the restore point. Your computer will be restored to the state prior to the event detailed in the "Description" field. If you are happy with your choice, click "Finish" and the system restore process will begin.
