Microsoft wireless display adapter not connecting to Surface Pro 3

Found the issue in my firewall, just need to figure out now how to apply a rule

Here's how I fixed the problem without a system reset.

1. Go into Device Manager and from View make sure show hidden devices s selected.
2. There should now be an item that has an exclamation point. Remove it and all of the devices with the same name followed by #1 #2 etc if there are any.  I'm sorry that I didn't make a note of what it was and I can't remember. But if this is your problem, it will be there. Make sure to uninstall all of the same named devices.
3. Restart. Do not rescan. I tried that and it didn't work. I had to restart to make it work.
4. After a restart I slide in from the right side and selected Devices from Charms. I selected project and the Add a Wireless Display was back. I tapped it and it found the MS Wireless Display Adapter. I connected and it worked fine.

I'm sure this has been resolved already...however...I had the same issue with my Surface Pro 3 and would like to share what resolved the issue.  It seems this is an inherent Microsoft issue that haunts them since Windows 98.  I remember having graphic card issues back then and I quite simply deleted the graphics driver from the Device Manager.  That's right deleted - then reboot.

The MS Display Adapter works beautifully with my BlackBerry Z30...two clicks and I was connected.  Therefore, it's not the adapter.  The fix is the following with Surface Pro 3:

Search for Device Manager > Double click Display Adapters > Right click Intel HD Graphics Family > Click Unistall > Check "Delete driver software for this device" > Click Ok > Reboot > Once fully rebooted, follow instructions to install MS Display Adapter (open right charms > Devices > Project > MS Display Adapter...) then bingo! You are now connected.

Worked like a charm!  ;)

"If you have a firewall, temporarily disable it. If you have AVG, open the program and click on "Firewall". Click on "change" to the right of the "Firewall Mode, Automatic". Select the bottom button that says "Disable Firewall (not recommended)" and click "apply". (This made me nervous, but AVG assured me that my virus scan was still active, and said that I could reactivate my firewall when finished with my display). I attempted to pair the devices and the projector works PERFECTLY. I can't speak to other firewalls, but my hunch is that by temporarily disabling them, the devices should connect. Hopefully this information is helpful. Please let me know if this works for you!"

The info on conflicts with  firewalls and AV programs is including in the Wiki article on Trouble Shooting Miracast.http://answers.microsoft.com/en-us/windows/wiki/windows8_1-networking/trouble-shooting-miracast/51d24be3-8d15-4c29-8e13-767ec365fbd8

• item #3.

I've had the same issue: MWDA was detected by SP3, but when I tried to connect, the SP3 screen flickered and connection was lost...

I was doing this as a non-admin... After I logged in as administrator it worked. Now it also works on my non-admin account. Might be a coincidence, but I'm glad it works now ;-)
