Fix: Wireless Display "Your display couldn't connect"

 You may find when trying to project to an wireless display Windows will fail with the following error message, even though other similar computers on your network can project just fine:

    Something went wrong.
    Your display couldn't connect.



Intel ProSet/Wireless Software > Modify > Wireless Software Extensions





Windows Defender Security Center > Firewall & network protection > Restore firewalls to default





Try again projecting and confirm it is working fine now.

  4. I had trouble projecting from my desktop to my laptop. The other way around would work fine. I discovered that it was because I had both my Intel Graphics and NVidia 1070 GTX adapters enabled simultaneously (I had enabled multi-gpu support in BIOS in order to force the onboard graphics to enable in conjunction with discrete graphics so that I could use the iGPU in XSplit as a video capture device while leaving my NVidia card and CPU dedicated to the DirectX game I was capturing. Disabling the iGPU in Device Manager on my desktop fixed it so that I could project to my laptop. When I was done projecting, I could re-enable Intel Graphics in order to assist with game capture in XSplit.

    TLDR; Windows can't handle Miracast properly with multiple graphics adapters enabled simultaneously. Disable the adapter you aren't using at the source in order to fix connecting to a remote display. Hopefully, Microsoft sees this and fixes it in a future build.

    1. Thanks Ahmed, I think you should post your findings back to Microsoft through the Feedback Hub.

    1. If I understand this correctly, your graphics driver has to support Miracast (run DxDiag > Save All Informatio button > Open text result and look for Miracast) and a wifi adapter (to suport WiFi Direct). I would suggest updating both drivers to the latest version available from AMD and then if still not working opening a thread on https://community.amd.com and https://answers.microsoft.com (Windows 10 / PC Projection)

  6. Miracast for Windows 7 is a new wireless display technology that is finally coming of age. Miracast allows teachers to magically display what is on a computer/device screen to a large screen HDTV or HDMI-capable projector WITHOUT any cables!

    1. Sorry to hear that. From what I understand, your graphics driver has to support Miracast and a wifi adapter that supports WiFi Direct. Run DxDiag > Save All Informatio button > Open text result and look for Miracast.

      I would suggest getting the latest versions of the graphics and wifi drivers from Intel (https://downloadcenter.intel.com/) either manually or better using the "Intel® Driver & Support Assistant", or whichever manufacturer for each. Check driver details or with the manufacturer if they support Miracast / Windows Wireless Display.
