OK, acquired it. Patch now. And markgo has some further recommendation:

Don’t hook your TV to the Web. Ever.

TV producers won’t ever pay for correct safety. Theirs is a low margin enterprise and as soon as the TV is bought, they aren’t going to spend any cash to help it. In fact, they’ll nonetheless make cash—by promoting your viewing information and promoting.

It’s a lure! So says u/robot_:

Feels like a trick to get me to reconnect it to the web. As soon as I noticed advertisements on my costly ass OLED TV, I knew it was time to disconnect it from the community eternally and let an AppleTV run the apps. I can’t consider anybody finds advertisements on a tool they paid for acceptable.

However should you don’t join it to the web, how will it get updates? Kevin McMurtrie is aware of what to do:

You plug it in periodically, within the hopes that sometime LG will repair bugs in HDMI/eARC or the video processors.

In reality, LG is fairly good about offline updates. As malor factors out:

You may replace LG OLEDs by USB, which is what I’ve been doing. The efficiency of my C2, as pushed by my PC, has improved considerably with updates. The precise user-visible habits hasn’t modified that I can see, however … I simply use it as a dumb display with no community. In the event that they’ve finished something evil, … I might don’t have any solution to know.

Wait. Pause. Sloth doesn’t consider the hype:

Except you may have particularly added a port … ahead in your router/firewall, it is a full non-issue.

In the meantime, right here’s ecofeco’s easy abstract:

Sensible TVs: Dumb thought.
