Bests & Worsts Reviews from Amazon

I've tried everything and can't can't sound output aside from the basic TV speakers. Hdmi arc and optical out modes for sounds do not work. I had an LG oleg TV from 2016 and I could get it all working just fine. Also, this newer model is more dim than more 2016. How did that happen? I would skip the 2021 LG model. A failure year for LG. I would return this if I wasnt too lazy to dismount it from my wall and pack it up. Too much work. Just a loss at this point.
