The Miracast wireless display standard allows a computer running Windows 10 to mirror the current display to an external display or projector. For this feature to work successfully, hardware compatibility with the Intel WiDi platform is needed.


Intel WiDi compatibility needed for Miracast to mirror a display within Windows 10

If your Windows 10 computer is not mirroring the display to an external display or projector using Miracast, the first troubleshooting step to take is to ensure compatibility with the Intel WiDi (Intel Wireless Display) platform. The Dell hardware relies on the Intel WiDi feature to support Miracast, so WiDi compatibility on the imaging device and the client system is essential.

SLN304839_en_US__1icon NOTE: While compatibility with the Intel WiDi platform is needed for Miracast to mirror a display in Windows 10, please note that Intel will no longer provide support for their Intel WiDi Adapter Software. The current version (6.0.66.0) will be the last release. Please refer to the following Dell Knowledge Base article for more information: Intel is no Longer Providing Updates to the Intel WiDi Adapter Software.

On the client system, three Intel components are required to support WiDi functionality within Windows 10:

  • WiDi supported Intel Processor
  • WiDi supported Intel Graphics controller
  • WiDi supported Intel WiFi card

WiDi technology requires a set of compatible hardware, drivers, and software to work properly. This includes, but is not limited to, wireless and graphics drivers for specific platforms for each supported operating system. Many of the features in Windows 10 will not function correctly on older platforms due to driver limitations. As result, the following limitations will prevent Intel WiDi (or Miracast) support for Windows 10:

  • Legacy WiFi adapters that supported WiDi may not support it for Windows 10.
  • 2nd generation Intel processors do not support WiDi in Windows 10.
  • External display devices must explicitly state that they support WiDi. If they do, older devices may require a firmware update to support it in Windows 10.
  • Dell systems with embedded non-Intel graphics controllers (such as AMD) will negate WiDi support.
