  • Mar 29, 2021 Open the Settings menu on your LG smart TV Check the “input” or “sources” option from this menu If it is set to “HDMI” or any other source, then you have located the problem Change this setting to the “mirroring” or “wireless screen sharing” option.
  • You will press the Smart menu key on your LG TV so that the entire menu will pop up on the screen. Use the navigation keys on the TV remote, find and select the Screen Share application listed on the screen. Finally, select the type of device that you wish to connect to for screen mirroring.

So I bought a new LG OLED55c8. I want to connect it to my computer because I want to use it as an additional screen. I find the TV in the 'add device' in the control panel. My TV also recognizes that my computer is attempting to connect. However, the connection fails and I'm prompted to try again. I'm running Windows 10.


Restart the devices that you want to use with AirPlay or screen mirroring. Learn how to restart:

  • iPhone, iPad, or iPod touch
  • HomePod*

Check for updates


Make sure that all of your devices are compatible with AirPlay and updated to the latest software version. Learn how to check for updates on:

  • HomePod*
  • Smart TVs

Connect your devices to the same Wi-Fi network

  • iPhone, iPad, or iPod touch: Go to Settings > Wi-Fi. Also, make sure that Bluetooth is turned on.
  • Apple TV: Go to Settings > Network. If your Apple TV uses Ethernet, check that the cable is plugged into the router that you use for Wi-Fi.
  • Mac: Click in the menu bar.
  • HomePod:* HomePod uses the same Wi-Fi network as the iOS device it was set up with. If your iOS device is in range of HomePod and connected to a different Wi-Fi network, HomePod will show an alert in the Home app that says 'Wi-Fi Network.” To connect HomePod to the same Wi-Fi network as your iOS device, open the Home app, press and hold HomePod, tap Settings, then tap 'Move HomePod to [Wi-Fi network]' at the top of the screen.
  • Third-party AirPlay-compatible speakers and Smart TVs: Go to the manufacturer’s website to learn how to connect them to your Wi-Fi network.

Check your AirPlay settings


If you can’t AirPlay to an Apple TV or HomePod,* check the AirPlay settings for that device.

  • On Apple TV, you might have restricted who can AirPlay.
  • On HomePod,* you might have restricted speaker access.
  • For AirPlay 2, you might need to invite others to control your home so they can AirPlay to your devices.

If you're using a Mac or PC, you can't AirPlay to HomePod* if you select Only People Sharing This Home.

Still need help?

If you have another issue using AirPlay, learn what to do.

If your music unexpectedly stops

If your music stops playing unexpectedly, use your device or Siri to start playing music again. In some situations, the Home app might be using your HomePod,* Apple TV, or AirPlay-compatible speaker as the main audio source for streaming music (even if your HomePod* or Apple TV isn’t currently playing music). Using Siri on that device or performing another task might cause playback to stop everywhere. You can also use an iOS device or computer with iTunes as an audio source to manually stream music instead.

If you see video but don't hear audio

If you don't hear audio when streaming video from your iOS device or Mac to your Apple TV, make sure that the volume is turned up and not muted on both your iOS device and your television or receiver.

If you're streaming video from an iPhone or iPad, check the Ring/Silent switch. If it's set to silent, you'll see an orange line. Toggle the switch to turn on the ringer.

If your content gets interrupted or your network lags

If you have a weak Wi-Fi signal or interference from a nearby device, like a microwave or baby monitor, try the following:

  • Make sure that you use the recommended settings for your Wi-Fi router.
  • Move or turn off other devices that might cause interference.
  • If you're trying to AirPlay to Apple TV, try connecting your Apple TV directly to your router with an Ethernet cable instead of using Wi-Fi.

LG Smart TV Unknown Device Is Disconnected Fix

Lg Tv Screen Sharing Not Working


Have you purchased a LG 'Smart TV' and found yourself inundated with 'Unknown Device Is Disconnected' messages? Well, let me show you how to permanently rid yourself of that nuisance.
After having a bad experience with an LG computer monitor many years ago, the last thing I would ever do is buy an LG TV. This LG 43UJ6300 43' Ultra HD TV was manufactured on October 2017 and came pre-loaded with firmware v03.60.50. It was purchased for me by a Best Buy customer service representative on November 22, 2017 as an 'equal replacement' for a Sharp 42' HDTV whose backlight had died under the terms of their Best Buy extended warranty I had purchased. The TV it replaced was a 42' regular HDTV, so I thought they were doing me a favor by giving me one inch bigger and Ultra HD. Little did I know that the smart TV was really dumb.
I was okay with it as a replacement at first, even though it lacks a headphone output jack like the old TV had. I had to buy a digital out converter to turn the digital out output into a headphone jack for those times when I want to watch loud TV late at night. For a year and a half, I had no problems with it. Of course, I was only using it as a regular TV. I had no interest in connecting it to the Internet or using any of its 'smart' features. That all changed in May 2019 when WWE announced that they would be discontinuing support for the WWE Network on PlayStation 3. I figured I'd use the WWE Network app through the LG TV I already owned, instead of paying $30 for a Roku Express stick. I would have had less headaches if I just paid the $30 and got the Roku.
On May 14, 2019 I started using the TV with the internet for the first time ever. The first thing I did was try to connect wirelessly to the router I have in the same room as the TV. It just hung on trying to find the wifi networks. That should have been my first sign that this TV's 'smart' features are a piece of crap. After exiting out and going back into the network settings, it found my router and there was no problem setting it up. I then set about downloading all of the apps I have/had on the PS3: WWE Network, Netflix, Vudu, Amazon Prime Video, Crackle, and YouTube. I also updated the TV's firmware, which involved going from v03.60.50 to v4.70.03, then to v5.80.02, and finally to v5.80.15 (which may not be the current anymore, but I'm not updating any further).
For a short while, the Internet-connected TV worked fine. Then I decided to change to a wired Internet connection. As the TV started to show ads and other garbage pop-ups every time I turned it on - I don't need to be reminded every time that it has a wired connection - I decided to unplug the Internet connection and only plug it back in when needed. From this point on, the TV had a mind of its own. There were several instances where it would restart (shut off and turn back on) without me doing anything. There were times when it was connected with a wired Internet connection, yet it would still show pop-up messages saying it was disconnected...only to magically be connected again two or three seconds later! On one night, Netflix played SO poorly on the TV, that I opted to connect the wire back to the PS3, where Netflix played beautifully. At this point, I decided to say 'screw you' to the 'Smart TV' and just buy that Roku stick later this year on Black Friday. (I don't need it right now as my sister has one on her TV, so I can watch the WWE Network there for the time being.)

The TV, apparently, realized I wasn't going to put up with its crap and decided to go all 'Maximum Overdrive' on me. I mean it didn't try to kill me. Well, it hasn't...yet. But that's when it decided to annoy the Hell out of me by popping up a non-descriptive 'Unknown Device Is Disconnected' message in the upper right corner of the screen several times each hour. Sometimes several times every few seconds. I did a web search and tried everything that other users had suggested, until I found the one thing that permanently solved the problem for me.
The cause of the problem is the Wifi Module inside the TV, though it also may be how a certain firmware version communicates with the Wifi Module. The only way to permanently solve the problem - aside from buying a new, non-LG TV - is to open up your TV and either clean, replace, or disconnect the Wifi Module. Also, do not upgrade the firmware, if you haven't done so already. Sadly, LG does not provide an option in the TV's software to disable pop ups in Home mode; that option only appears in store mode, which does not save picture and audio settings. That's why opening up the TV is the only way to go. (You can click on all of the images below to have enlargements opened in a new window, so you can take a better look at the details.)
What I'm about to demonstrate should only be done for TVs that are no longer under the one-year warranty. If your TV is still under warranty, call LG and have them handle it. Opening your TV will, likely, void the warranty. Please do NOT e-mail me or post comments asking how to do this on other model TVs. They will all, likely, have the same wifi module component in the same place, or someplace very similar, but they will have a different number of screws and different placement of the screws on the back. You will have to figure that out. Use this as a general guide for other LG TVs, but not as an exact guide.
1. Locate all of the screws on the back of your TV. The 43UJ6300 has 8 screws: 6 along the bottom, 1 by the side connectors, and 1 nearly-hidden by the back connectors.
2. You *MAY* also have to remove the legs, if you have your TV standing on its own instead of being affixed to a wall. I'm not 100% sure you need to remove the legs, but I did it anyway.

3. Once you open it up, you'll be surprised by how little there is inside. The Wifi Module is located at the bottom middle of the unit, right next to the power button.
4. The Wifi Module is held in place by the Wifi Bracket. On this TV, the bracket actually says 'Wifi Bracket' on it. There is only one silver screw holding it to the TV, which is clearly visible on the right side. The top of the bracket is also clipped under part of the TV, but that'll be easily to see once you unscrew it. (NOTE: If you're just disconnecting it, you *may* be able to disconnect the white ribbon cable running from the main board to the top of the wifi module without having to remove the bracket. That said, it'll be easier and safer to remove it after unscrewing the bracket, as you don't want to damage anything.)

5. Here we see the 43UJ6300's Wifi Module, which is attached to the bracket. For this TV, the sticker lists a LG Part Number of 'EAT63435701' with a manufacture date of September 14, 2017. The module itself is branded with a Product Name of 'RF Module' and a Model Name of 'LGSWFAC71'.
You have a few options on what to do next, depending on whether you want to wirelessly connect the TV to the Internet or not.
A. If you will NOT BE USING WIRELESS INTERNET, as was my case, you can simply (but carefully) disconnect the white ribbon cable from the Wifi Module. You can easily see it in the photo above. Mine took a little bit of effort to unclip from the module, but it was still really easy. You can still use a wired Internet connection, if you want, or just leave the TV as a TV and use Roku (or a similar device) for 'Smart TV' features.
B. If you WANT TO USE WIRELESS INTERNET, BUT DON'T WANT TO SPEND ANY MONEY, you can disconnect the white ribbon cable from the Wifi Module, clean the connectors with a microfibre cloth, then reconnect it. Some users have reported success with this, while others say that the message eventually comes back.
C. If you WANT TO USE WIRELESS INTERNET, AND WANT A SOMEWHAT GUARANTEED PERMANENT SOLUTION, you can buy a new Wifi Module. They are really cheap. For this TV, a LGSWFAC71 Wifi Module would cost about $10 to $20. Searching for EAT63435701 brings up different results for about the same price.
6. Since I chose to disconnect the Wifi Module, I taped the loose ribbon cable to the inside of the TV with a note saying, 'Wifi Module disconnected, so as to disable 'Unknown Device is Disconnected' message.' That way if anyone ever looks in there in the future, it will be known what was done :-)

And that's all there is to it. My Wifi Module has been disconnected for over two weeks now, and the 'Unknown Device is Disconnected' message has never appeared again. I hope that this TV lasts me a really long time, but if it doesn't, I hope that I'm never saddled with another LG product ever again. LG truly stands for 'Like Garbage'.
