Miracast - Whats it and how to check for it?

Miracast is an open standard to connect your screen wireless with Miracast capable TVs or Miracast dongles. These dongles need typically an external power and provide an HDMI connector for your screen or beamer. 






As it is an open standard it works also with Android devices. Chromecast is nothing else than Googles name for Miracast. ;-) The only exception as always is Apple. Apple only works with Apple and nothing else. Means when you want to use such a function on Apple devices you need specifically Apples Airplay feature.


Miracast is a further development from originally Intels WiDi (Wireless Display). And it is supported since Windows 8.1.


To make sure your device is supporting it please validate that you have the latest wireless NIC and video card drivers.


It uses a standard called WiFi Direct. This is a second direct wireless connection between your Miracast adapter and your device. This ensures that you can surf in the internet while streaming your video to the Miracast capable device.


Wireless Network Interface Card (WLAN NIC)
NDIS Version minimum supported  6.30
Powershell Command to check is:
Get-NetAdapter | Select Name, NdisVersion




Video Driver Support
To check the support for the video driver you need at least an WDDM 1.3 driver version!
Therefore simply start the diagnostic program "DXDIAG" on your system.
Open the tool and click on "DISPLAY" tab and check the driver model.
