Windows 10: Can't connect to Miracast

I am having the same problem.

I have, per the last instructions, removed the offending device.

I then navigate to the WIN 10 Devices page to confirm it is gone. Secondly I navigate to "connected Devices" and it is not there either.
The Device is a wide screen TCL ROKU Smart TV 4k edition. In the TV settings I have confirmed it is connected to the correct WiFi that my PC is connected to. Screen Mirroring is enabled.

The Problem:
I go to the Action Center, expand the icon listing to see both "Connect" and "Project". I click on Project and do not see my device. I click on "Connect to a wireless display". I see only my two bluetooth headsets and sometimes I will see my LG soundbar connected to the TV. The TV itself does not appear.

That screen has an option for "Find Other Types of Devices". Which, in what I am getting used to as MS Win 10 going into its "I have no idea what's going on..." loop, I get sent back to the "Connected Devices" pane of Settings.

NOW, here I try to "Add a Device" and... wait for it... It finds the device labeling it as an "Entertainment Device", runs through it's progress bar (doing whatever Win 10 does when this happens), and the device shows up on the "Connected Devices" list.

Now is when I get ready to bail on WIN 10 as absolute junk. The thing still won't show up as a wireless display that I can cast to.

Per DXDIAG and the netsh command for such things my system is capable of wireless displays.

What the heck.

 

"Connect" and "Project" don't work.
Edge will work if it's something that can be cast (miracast), i.e. video or photo.
Photo Viewer might work, too.
Look for "Cast media to device", when Edge is looking at a video or picture.

Wifi direct requires that the TV only have wifi enabled, there is no router involved, hence the name "wifi direct".
On my Sony TV, it will override what ever is being shown on the TV. Sometimes have to turn the TV off to reset.

 

Thank you. Very informative. But as I was trying to cast some TV over to the Smart TV from my PC using KODI. This is a significant, albeit annoying issue. Now I need to figger out how WiFi direct works

 

It may be stupid, but make sure your TV is connected to the same Wifi as your laptop or PC.

 

Never stupid, but, in my earlier post I did state that my connected devices pane "saw" the T.V.
I am pretty sure it could not unless the WIN 10 PC and the TV were on different networks.

Also when I check the network settings on the TV it is on the correct network.
There is another issue. Earlier someone posted that the "Project/Connect" functions just don't work in Win 10.

With that I did notice that some APPS can broadcast to the TV. With that in mind I found the ROKU Media player app. That APP can see the KODI app folders on my PC. I am beginning to believe that in WIN 10 apps have to exist on both ends to allow "screen casting" to function, say an transmitter and a reciever app, but no.... Tube Cast requires no receiver app. iit just works.

Wierd Stuff. But, It's Micropsoft. They are so crappy they could screw up a whores wet dream.

 

I wanted to jump onto this old thread to let people know I found a simple solution for connecting a Windows 10 pc to a wifi display, using the Connect app in the notification area. When you click Connect, check you Anti-Virus app for Firewall connections. You will see the new connection listed as Public. Switch that to Private and it worked for me...worth a try. I struggled for weeks with this problem.

 

ugh...

Seems to be a number of steps missing here mackjay. When I click "connect" in my notification area I never see any firewall or Anti- Virus app things. So I am missing something here.

 

You have to go to your anti-virus program and look at the firewall setting. Be sure your network is set to "Private". Mine was defaulted to Public (Avast Anti-virus), when I changed to Private it made the connection work. In other words, your anti-virus could be blocking the Miracast connection.
This was on my PC. On the tablet I only have Windows Defender for anti-virus. I noticed the firewall is set to Private and the connection works on that as well.

 

Okay

There is very little in my McAfee firewall settings that mentions or governs the "private" or "public" status of my network connection. IF I look under firewall settings I can find a section called My Network Connections. In there I can see my network. But the only hint here that this is a private or public network is buried one more layer, but it only says in the description that it was Automatically added by trusting a private network.

There is nothing here that lets me change that status. So, guessing at the missing steps, I go to my network and sharing and check there. Buried three layers down from the nominal windows "settings" app screen I find my connection in Network and Sharing under the Control Panel there is a item that says the network connection is Private. From HERE I can go to "advanced" settings and turn on things line "network discovery" for BOTH private and public networking. On my system all of the network discovery and automatic setup of connected devices IS turned ON.

Still my ROKU TV will not see my WIN 10 PC in the lists for allowed or blocked devices. It's a ROKU TV It is connected wirelessly to network and I get my streamed television in that manner. BUT I can not miracast from the WIN 10 PC to the ROKU TV even though the ROKU TV IS listed as connected under "other devices" in the "Connected Devices List" in the Settings app interface that WIN 10 uses.

So as far as I can tell from all of this is that I have met all of the conditions set forth here, and they fail. Unless there is something that I missed this did not work.

 

Well now this is interesting.

Buried DEEP in the Network and Sharing Center, via a link on the left side menu is a link marked "Change Advanced Sharing Settings". Way down here, well away from ANYTHING you can easily find through the nominal WIN 10 settings options is this place where you change the sharing options of WINDOWS.

Here there are three major sections:
Private [mine says] "(current profile)"
Guest or Public
All Networks

Private, Guest or Public, BOTH HAVE SEPARATE CONTROLS FOR TURNING ON NETWORK DISCOVERY

Then there is the All Network section in here I MAY have found my problem. In this All Network Section is a category called "Media streaming" with a link to choose options. HERE FINALLY I get a hint as to what is wrong. There is a button here to turn on or turn off media streaming. Mine is OFF by default. I am turning it ON to see if that changes anything.

I will return if THIS works.

This little beast my lay at the heart of a lot of people's problems. This area says my streaming media is not turned on. Yet when I press the button it won't work. I do NOT get the ok button to turn it on. At least I have something else to research.

 

AWinter, I did what the other user stated of changing the network to private, you need to open the firewall settings and when attempting to connect you'll see a new network is trying to connect, you need to change that to private network and the firewall settings will allow the pop up and you'll be connected to your tv, hope this help.

Thanks!

 

I'm glad to see this has worked for at least some. In case you want more info, here is where I found the solution for my situation. I use Avast anti-virus, but this may work for other brands. Scroll to the final message in the thread for the solution: Avast Firewall Blocking miracast display
