The LG “screen share” option is a very convenient feature that has brought peace
to many households. However, when this option does not work, it can be a huge pain. Like
every problem, this problem has easy fixes too!
These solutions are mainly targeting screen sharing issues via PC/laptop. If you are using
your iPhone or Android, head over to our blog, there is a link to it below, here we mention
phones as well.
Without further ado, let’s troubleshoot your LG TV screen sharing!
Number 1. Restart your TV, Computer, WiFi, Router
By simply rebooting your computer or laptop you will most likely solve the minor software
glitch that is preventing your device from mirroring properly. If this doesn't help,
also reboot your TV and the Wi-Fi router too.
Number 2. Power Reset Your TV
Another very effective thing to try in any kind of TV-related issue. Unplug the TV power
cord from the wall, wait for 1 minute, plug the power cord back in.
Number 3. Use Window-P or Display(F10) To Connect
When you are trying to screen share from your laptop or PC, try using Window-P ("Presentation
display mode") or Display Button instead of Windows+K ("Connect quick action") to open
the window which connects you to the TV. Once you press the button, the window as shown
in the picture will appear. Click Connect To Wireless Display
Find your TV in the list of the options on your Laptop
Click on it to establish the connection
Number 4. Delete Pairing History On LG TV
Most TVs only allow screen sharing with one device; therefore, you may be facing an issue
with connecting a new device. Remove any devices that the “screen sharing” app shows. This
option can be found by navigating to the “delete paired devices” option on your LG smart
TV. Once the connections are removed using the remote, and following the on-screen instructions,
you can then attempt to pair the TV with a new device.
Follow these steps to delete your pairing history:
Open the Screen Sharing window on your LG TV
Click on Delete Pairing History with your remote
That is it. You can also restart your TV to make sure everything works smoothly.
Number 5. Use Ethernet cable
If the wireless connection is still failing you, try switching to the good old Ethernet
cable instead. First, connect your TV and the Ethernet cable, then turn on your WiFi.
Number 6. Disable Your Firewall
Sometimes your Firewall in your anti-virus might be hindering the connection of your
TV and the device you are trying to connect. So try disabling your Firewall Protection
and see if it does the trick.
Number 7. Check Your Network
In order for the screen sharing options on your TV to work properly, both your TV and
the device you are trying to screen share should be connected to the same WiFi network.
Number 8. Turn Off Quick Start/ Simplink Features
Some features that were meant to make your TV smart sometimes have the opposite effect.
Let's try tweaking a few settings to see if they were the culprits. On your remote, simply
go to Settings>All Settings>General>Quick Start/Simplink>Off. After you do that, turn
the TV off, wait a minute, turn it back on.
Number 9. Turn off Bluetooth
Both Bluetooth and screen mirroring options use wireless technology, so they might interfere
with each other. Check if your Bluetooth option is turned off on your TV, restart it, and
then try again.
Number 10. Check for the Right Input
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. Additionally, you
can attempt to set it to “Bluetooth” as well for some methods of connecting your devices
wirelessly.
Number 11. Remove the Obstacles
There is a chance that the screen mirroring has failed to work because some objects are
blocking the wireless signal. Make sure there are no objects like a microwave and baby monitor
located near the TV or your smartphone.
Number 12. Check your WiFi router
The Wi-Fi router is used in this process, so you need to check the WiFi router if the
problem still exists. See if it has sufficient bandwidth or not. Remove all other devices
connected to the router, apart from the laptop and the TV. Then try to attempt the connection.
If it does, that means the problem was with the router and not your two devices.
Number 13. Use Third-Party Devices
If all has failed to work, try using a separate streaming device like Chromecast to use the
screen mirroring function on your LG TV.
