What you’ll learn in this article:

What is Miracast?

Miracast is a standard wireless connection technology. It enables you mirror the device screen like laptops, tablets, smartphones to the displays like monitors, TVs and projectors without a USB cable. So you can simply regard Miracast as “HDMI over Wi-Fi“. 

Miracast now comes built into some devices, Windows 10 is one of them. If your display device doesn’t have the Miracast support, a Miracast adapter such as a Microsoft Wireless Display adapter can help you solve this problem. 

Read on to see how to use Miracast…

How do I solve Miracast not working on Windows 10?

See the error saying “The device doesn’t support Miracast, so you can’t project it wirelessly” when you check if your Windows 10 is ready to go? Don’t worry. The following solution may help you fix the problem.

  1. Is your Windows 10 from a upgrade of Windows 7 or other earlier version? 

    If so, your Windows 10 may not have the built-in Miracast support. In this case, you can make use of a Miracast adapter, like Microsoft wireless display adapter.
  2. Is your Windows 10 is of a clean-installed version? 

    If so, it should support Miracast then. Then why does this error still happen? Probably your display or Wi-Fi drivers are to blame. You can solve the problem through updating your drivers.

    To update these drivers, the direct way is to download from the manufacturer’s website. If you’re not comfortable playing with device drivers, we recommend using Driver Easy. It’s a tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs.
    1. Download and install Driver Easy. Then run it on your Windows.
    2. Click Scan Now.  All drivers problems of your computer would be detected less than 1 min.
    3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
      Note: You can do it for free if you like, but it’s partly manual.

    4. Reboot your Windows 10 and try to set up Miracast again.
