How to block "<xxx> requests screen sharing to your TV" dialogs appearing on your TV.


Has anyone else experienced someone from "outside" trying to request screen sharing?

A dialog popped up on my LG OLEDTV recently:

" requests screen sharing to your TV
Do you want to accept this request?"

Now this was someone from outside trying to connect to my TV (from an Android phone, as it happens), and apparently, there is no way whatsoever to block this from happening. They don't even need to be connected to my WIFI to make dialogs appear on my TV.

I asked LG about it, and all they could offer was:

The only way to stop this from happening will be from not accepting the request and to try and find who is connecting and asking them to stop.

Am I the only one who thinks this is completely unacceptable? There should be a way to block people from outside my household from intruding themselves on my TV. It should be possible to block screen sharing completely, but it seems not.

On a completely different topic, I've never seen so many adverts taking up so much screen space on any other web site. If I didn't have a good enough reason to use an Ad Blocker before, I do now! Advertising on the Internet is completely out of control.



  • This has happened to me now 3 times now in 2 months.
    Am I the only person who has had this happen?
    It is very annoying! Just watching the TV and suddenly this "unsolicited" dialog pops up, presumably from someone walking by outside. I do not believe it's a neighbour, as it's a different device each time.
    There needs to be a way to turn this "feature" off.


  • I understand your concerns about privacy and intrusive screen sharing requests on your LG OLEDTV. It can be unsettling to have someone attempt to connect to your TV without your permission. While I can't provide real-time updates on specific issues or threads beyond my knowledge cutoff date in September 2021, I can offer some general information and suggestions.

    Check for Software Updates: First, ensure that your TV's firmware is up to date. Manufacturers often release updates to address security and privacy issues. If there's a known vulnerability, a software update might help mitigate it.

    Review Sharing Settings: Check your TV's settings for screen sharing or mirroring options. Some TVs allow you to enable or disable screen sharing features. Make sure they are set according to your preferences.

    Network Security: Ensure your home Wi-Fi network is secure with a strong password. This can help prevent unauthorized access to your devices.

    Contact LG Support: If you haven't already, reach out to LG support again, explaining your concerns and asking if there have been any updates or solutions to this issue since your last inquiry.

    Change Your Network Password: In cases where you suspect someone might be attempting to access your TV without permission, consider changing your Wi-Fi network password. This can help prevent unauthorized access to your network.

    Firewall and Security Software: If your TV allows for it, you might consider using a firewall or security software that can help protect your TV and other devices on your network.

    Regarding online advertising, it's a common concern, and many users choose to use ad blockers to improve their browsing experience and reduce the intrusion of ads. However, it's worth noting that while ad blocking can help with ads on websites, it may not directly address issues related to your TV screen sharing.

    Please remember that the specific features, your Internet Package and settings on your TV may vary, so it's essential to refer to your TV's user manual or contact LG support for the most accurate and up-to-date information on managing screen sharing and privacy settings
