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.

Let’s look at some of these method that we can do with this Dell Miracast Windows 10 problems

Method 1: Update Intel WiDi Driver for Dell Laptop

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 ( will be the last release.

Before we update the WIDI driver, you need to know about the compatibility of your device. So, we recommended to read this before.

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.

Problem by Foxbass

Bought Chromecast, followed directions, can’t get e6430 to connect. Have the correct miracast opening screen up on tv set to windows . Laptop claims it does not support miracast. Yet it is a 3rd gen processor with intel graphics. Have set lattitude to search for new device but it cannot find anything other than existing phone, wireless speaker, wireless head phones and fitbit.

You should be able to activate Miracast by holding the Windows Key down, pressing “P” (for “project”), and then clicking “Connect to a wireless display” in the sidebar that appears.

If that’s not working, then where exactly is the laptop claiming that it does not support Miracast?  And what WiFi card do you have?  Miracast is a notoriously finicky and ill-supported protocol, but if your system claims it doesn’t support it at all, then that’s probably your answer, and it’s probably related to the WiFi card.

If you wanted to upgrade that, the Intel 7260HMW would fit into that system and probably be a significant upgrade from whatever came with an E6430.  They’re about $30 on Amazon, but make sure you get the Wireless-AC 7260, not the Wireless-N 7260, since the latter only supports 802.11n.

I have no idea why Intel used the same model code for two different cards that have vastly different capabilities, but they did.  It’s also important to get the HMW, not the NGW in your case.
