How to Fix Miracast not working on Windows 10

If you are one of the users who did not have the Miracast Status as Available, there’s no need to worry. You can still use Miracast on your computer to project display wirelessly. How?

There can be one of the two reasons behind this issue:

1. Did you Upgrade your Computer to Windows 10?

Is the Windows 10 installed on your computer is an upgrade from Windows 8 or other previous OS? If yes, that means Windows 10 on your device might not have the inbuilt Miracast support. If you want to use the Miracast technology on your computer, you will have to buy a Miracast Adapter. Miracast Adapters are easily available in the market.


2. Your Computer had Windows 10 pre-installed?

If your computer came with Windows 10 pre-installed, then you should have no problems using Miracast. The problem is probably due to outdated Wi-Fi or Display Adapter’s drivers. Simply update the drivers and you will be free of this issue. You can update the drivers from your computer’s manufacturer’s website.
