How to Setup & Fix Miracast on Windows 10

If you are frustrated with squinting at your smartphone or tablet device to read those tiny lines on streamed videos and presentations, or your super-gaming effects are crippled due to a small screen, Miracast is the solution tp your problem. With Miracast, you can magnify the display in your mobile or tablet in a screen as big as your TV. Read on to learn what Miracast is and how to set it up quickly on your Windows 10 system.

What is Miracast?

As tempting as it is to call Miracast a device, it is in truth a wireless technology standard launched by the Wi-Fi Alliance to facilitate seamless connections between TVs, laptops, smartphones, and projectors irrespective of their brands.

What Miracast-enabled products can do is essentially mirror the small screen of your smartphone, tablet, PC or laptop onto a bigger screen like a TV or projector screen without the need for any Wi-Fi network or HDMI display cables. The only thing you need is for the connected devices to be in close Wi-Fi range.

For the Miracast technology to be fully utilized, both the transmitter (phone, laptop or tablet) and the receiver (TVs, projectors) should support Miracast. While the latest gadgets and operating systems have the technology built-in, unsupported devices can be made Miracast-ready by using specially designed Miracast adapters.

Luckily, Windows 10 comes with built-in Miracast support, making it easy to connect with other devices. But if you have upgraded to Windows 10 from prior versions of the Windows operating system, they may lack current drivers. To ensure that your Windows 10 device does support Miracast, first run the quick test below.

How to check if your Windows 10 device supports Miracast

  1. Press Win+R in your keyboard.

  2. Type dxdiag and click enter.

  3. Click on Save all information at the bottom of the screen that appears and save the text file to a location of your choice.

  4. Open the text file and search for Miracast. If enabled, you’ll find available next to it.

Fix common Miracast problems on Windows 10

As simple as the setup is, at times you may run into problems while setting up Miracast. You may get an error stating that "The device doesn't support Miracast and you can't project wirelessly". Below are some fixes and suggestions when you try connecting your display device to Windows 10.

  1. Device Drivers not updated - As mentioned earlier, if you had a Windows 8 and then upgraded to Windows 10, then your device drivers may not be the current versions. The latest drivers need to be installed.

  2. Display adapter not working - In case your display device doesn't have built-in Miracast support and an adapter is used, chances are the adapter was not a right fit for your device and has to be replaced.

  3. Wi-Fi not enabled - Though the Miracast transmitter and receiver don't have to be on the same network, the Windows 10 PC should have the Wi-Fi option enabled.

  4. Restart and Reconnect - Restart your PC or mobile and remove the connected display device. Now retry the connection from the beginning as described in the steps above.
