Most TVs are dumb if you never hook them up to the Internet. I don’t allow my OLEDs on the Internet generally and simply use a different device to stream and do all the things (webOS is actually pretty cool but LG is obnoxious like this sometimes). Even if your TV is good enough, this shit happens anyway. At least if my shield gets obnoxious, I can replace it with a different device.
If it’s any consolation I don’t think any of them I’ve run into REQUIRE Internet to use them as a dumb screen. I wouldn’t buy one that did either. Lol.
