Screen Share with Windows 10

[Manav Dhingra]

You simply need to  disable Intel Management Engine Driver in system devices in  Device manager (Win+X+M) , then it works flawlessly every damn time, it's not LG's fault, it is Intel's . You can enable it once connected and what's more, if you change projection mode to 2nd screen only, you can use your pc at 2560x1600 @30Hz.

Hello,

I have a LG50UM76 and I don't even see the screen sharing app in the menu.
On another model I could find it but on this one not, how can I make it appear?

One more thing to try is to set wireless adapter to maximum performance.

Settings > Power & sleep > Additional power settings > Change plan settings > Change advanced power settings > Wireless adapter settings > Power saving mode

Hey Everyone and thank you all for the thread and the tips! I also created the account just to say thanks and share/highlight this solution:
 

• Both my TV and Laptop were getting internet from the same Wi-Fi network
• I disconnected them both from WiFi, leaving the wifi radio of both ON
• I restarted the Laptop
• Then clicked the PC's "New notifications" window (down right corner) and chose connect

and it worked. It seemed that Laptop the restart was crucial.

If that doesn't work you could try after the restart to click from the PC's "New notifications" window first

• Just in case you can switch on the  media streaming options from the windows menu

   as per
• Project and then choose duplicate or extend
• and then the "Connect" or the "Connect to a wireless display"

Hope this helps and much luck to all of you! After all I'd prefer HDMI if possible as strangely the connection seemed a bit sluggish.

Cheers and good luck again

FYI: the above setting is VERY important, for device and multimedia sharing, as @KPWK has found. You get a nice GUI wijdow where you can allow or disallow devices as required. NOTE: it often happens that Feature Updates to Windows10  (and some large updates) e.g. 1809 to 1903 etc will reset the Media Streaming back to OFF, so DO remember to recheck after any big update or Feature Upgrade happens, and set it back ON if needed.  Also note, that many older TV models might only use the 2.4G WiFi, so ensure both devices use the same network, and not have your sending device on the 5G one.

FYI: for those that have devices that have Miracast support inbuilt (e.g. a later Windows 10 OS device), here is a useful article to read and try out if it works with your TV. No guarantees of course, as there are a few catches and caveats, as the post threads here show.

This isn't working. I keep getting the "Couldn't connect" error 

[dejavu619]

Managed to finally resolve this problem:

 

1. Connect your laptop to the router using an ethernet cable. Don't worry this is only temporary.

2. Connect the TV's Wi-Fi to the same network that the laptop is connected to

3. Start the Screen Share app on the TV

4. On your laptop, choose the option to connect to a wireless display and choose the name of your LG TV

5. Once your laptop display has been cast, you can connect to WiFi and remove the ethernet cable from your laptop

Hi all,

I was also struggling to get this to work. Wasted many hours. Here is what eventually worked for me... I'm running both a Surface Book/Surface Book 2...

I had to set the frequency band on the WLAN adapter for the Surface Books to 2.4ghz... Join the 2.4ghz on the LG Smart TV (OLED running WebOS). That worked for me. I tried on the 5ghz but no luck. However on my Galaxy Note 8, I'm able to miracast on the 5ghz band with no issues. *shurgs*...

I do notice on the 2.4ghz band, there is a bit of a lag on fast motion. But on the 5ghz (phone) it's smooth.

I hope this helps others.

Nothing has helped. I've tried EVERYTHING. I've spent maybe 30 hours now working on this. I can cast other devices to my LG EF9500, I can cast my pc to my other pc. I think it's a driver issues with my network adapter Intel wifi6 AX201 and the TV getting past the authentication/security handshake. I see my TV in "connect a display", I get a notification on the tv that my PC is trying to connect. It just never does.  There was a driver update maybe a year ago with release notes saying it fixed issues connecting to LG TVs. Tried that driver, didn't work. I've tried several drivers for both network adapter and display adapter. This has been so frustrating. It's definitely the last time I pay LG $3,500 for a TV.

In event viewer under administrative events, I see errors every time I try to miracast to my tv. It says event 6062 Lso was triggered. Source: Netwtw10 (which is a driver) 

\Device\NDMP43

Intel(R) Wi-Fi 6 AX201 160MHz

 

Can anyone tech savvy help?

Try to disable Intel management engine under Device Manager > System Devices

I've wrestled with it, too. Check if your PC and LG TV are on the same Wi-Fi network. Sometimes, that's the sneaky culprit. Also, make sure your TV and PC firmware are up to date. If it's still playing hard to get, a good ol' restart often does the trick! And if you decide to install Windows 11, check out this site with deals (
