With Windows 8.1 natively supporting Miracast, we saw a demonstration of screen mirroring via Xbox One at the ongoing //build/ conference. If I want to mirror my laptop screen running Windows 8.1, what extra hardware would I need both on receiving end and transmitting end to support Miracast?

    Would people who are downvoting/closing this question also please explain why they are doing so. – Mayank Jun 28 '13 at 02:00

Transmitting end:

  • WiFi device with NDIS 6.3 driver. (Check with Get-NetAdapter | Select Name, NdisVersion in PowerShell.)
  • Video driver that supports WDDM 1.3 (new for Windows 8.1).

Receiving end: Any device certified for Miracast? Netgear Push2TV confirmed to work.

    You can in powershell write: "Get-NetAdapter | Select Name, NdisVersion" to get the NDIS version of your WiFi card... And you can run: "DxDiag.exe" to find out what WDDM version your graphics driver is... – mattsson Jul 17 '13 at 20:40

    Per @zmurf I checked and my graphics card driver model is WDDM 1.3 and my Wifi NDIS version is 6.3. This tuturial (http://blogs.msdn.com/b/matt-harrington/archive/2014/05/02/how-to-project-from-a-computer-to-a-tv.aspx) suggests I cannot mirror. Is there something else I need? – MrMas Oct 03 '14 at 03:44
  • Same here. WDDM 1.3 and NDIS 6.3. I don't have the option to add a wireless monitor. – Pluc Nov 19 '14 at 16:12

    Turns out that not all WDDM 1.3 drivers support Miracast. Upgrade to the latest driver available at the manufacturer's web site and see if that helps. NVIDIA did not add support until around a year after Windows 8.1 was released. – Truisms Hounds Jul 07 '15 at 20:32
