Miracast is a wireless connections standard that displays content from laptops and smartphones on projectors or TVs. Any display can act as a receiver as long as what is powering it supports the Miracast standard.
Miracast supported devices
The technology involved uses the peer-to-peer Wi-Fi Direct standard requiring specific devices for communication. Users have at their disposal adapters plugged into USB or HDMI ports to add devices or displays which do not otherwise support Miracast natively.
Most of the latest computers running Windows 8.1 and 10 should support it, which means users may display the screen in another display such as a TV.
Verify if your computer supports Miracast
You can easily find out if your PC running Windows 10 supports Miracast or not:
- Tap on the Windows-key, type connect, and then press Enter. You’ll get the message “The device doesn’t support Miracast, so you can’t project to it wirelessly” or “’name’ is ready for you to connect wirelessly.”
Things will be a bit different in case you’re using Windows 8.1. You can run the DirectX Diag in order to get your answer, but this might not be very reliable. Here are the recommended steps:
- Press the Windows-key, type dxdiag.exe, and press Enter
- Confirm any prompt that will appear and wait for the scanning process to end
- Select Save All Information and pick a local directory
- Open the saved dxdiag.exe file and locate the Miracast entry
The wireless adapter also needs to support Virtual Wi-Fi and Wi-Fi Direct. You’re going to need a device that supports at least NDIS 6.3 because Wi-Fi Direct was implemented in that version.
The display driver also needs to support WDDM 1.3 and Miracast. If your driver is updated, it should be fine. Here’s what you need to do in order to find out:
- Press the Windows-key, type powershell and press Enter
- Use the command Get-NetAdapter | Select Name, NdisVersion to list the supported NdisVersion for every network
- Make sure it is at least 6.3
For WDDM support, you should check the previously saved DxDiag diagnostic log. Search for WDDM to display the support version.
