1] What is Miracast
Miracast is a standard for wireless connections from devices like laptops, tablets, smartphones, etc., to external displays or larger screen like TVs or monitors. It can broadly be described as “HDMI over Wi-Fi”, replacing the cable from the device to the display and making it work on a wireless network.
Nowadays Miracast support comes built into the device, and it was first offered in Windows 8.1. With Miracast, you can easily create a wireless connection between your computer and other display devices such as Monitors, TVs, and Projectors. Miracast allows sending up to 1080p HD video (H.264 codec) and 5.1 surround sound which is more than enough for average users.
There are many advantages of using Miracast. The list includes faster content projection, works over the existing network, works with older wireless hardware, and automatic detection of receiver support. However, it is not here to replace an older way to connect to projectors but offers a modern approach i.e. wireless technology, if you have the right set of hardware.
2] How to check if Miracast is supported on your device
Press ‘Win+R’ on your keyboard and then type in ‘dxdiag’ and hit Enter.
Press the ‘Save all Information’ button located at the bottom and save the text file at the desired locations.
Now open the text file and look for ‘Miracast’ and next to it will be the current availability status.
An alternate way to check Miracast support is by going to Display settings (Windows 10 Settings > System > Display). Once you are there, look for Connect to a wireless display under Multiple Displays and click on the Detect button.
3] How to get current Miracast drivers for your PC
These methods apply to displays that directly support Miracast or support through third-party Miracast hardware. The latter can make any display a Miracast capable device.
Microsoft offers an app available in the Microsoft Store—Microsoft Wireless Display Adapter—that you can install. Once installed, it will also install the wireless driver that will work with your current display if it supports Miracast out of the box.
If the display doesn’t support Miracast, then you can use an external device. Depending on the OEM, Windows should be able to download and install the driver. If not, you can go to Windows 10 Settings > Update and Security > Click on Optional Updates.
Locate the driver for the third-party Miracast adapter or Miracast Receiver, and install it. You can also download the software directly from the OEM website and install it.
4] Set up & use Miracast on Windows 10
Step 1: If your TV comes with built-in Miracast support, then turn it On. Else connect the external adapter into the HDMI port of your television and power it on.
Step 2: Now on your Windows PC, navigate to Start -> Settings -> Devices -> Connected Devices.
Step 3: Click on ‘Add a Device’ and wait for the adapter to appear in the list. Click on the receiving adapter and that’s all. You’ve set up the wireless display.
You can now configure both the displays by pressing ‘Win+P’ and selecting a relevant option.
If that does not work for you, repeat the steps again and check.
5] How to wirelessly project your Windows 10 PC to an HDTV
Now that the device is available as one of the external displays to which you can mirror or project your computer, follow these steps to project.
Step 1: Open the Action Center, and click on the Project option. You can also use Windows + P
Step 2: This will bring up the option which is used to duplicate or extend the display. In the end, click on the Connect to a Wireless Display link.
Step 3: This will open another flyout where new devices can be scanned using the Wi-Fi connection, and the older connected screen will be listed. Select the device you have configured earlier. Once connected, your Windows 10 device should now be mirrored over the WiFi network using a video stream.
Note: This works even if your laptop is connected to Ether as it will use the wireless adapter to project.
6] Windows 10 Miracast not working
Sometimes you face problems in making Miracast work like you may get a not supported message or there may be no sound. Try these suggestions:
- If the connection doesn’t work out for you, the first thing you need to check is your device drivers. Ensure that all the Display and Wi-Fi drivers are up to date and your computer supports Wi-Fi direct.
- If the problem persists even after updating and installing proper drivers, then it is recommended to try out another Adapter. I would recommend the Microsoft Wireless Display Adapter. Due to a lot of manufacturers and available variety of products, there could be any compatibility issues.
- Make sure you are setting this up on a secure Wi-Fi network. It may not work on an open Wifi network.
- The last and final step to the solution would be to consult the respective manufacturer and ask for a solid solution to the problem.
