Seven years ago I bought a 32-in HD TV from ALDI, it's OK but not so fabulous in this day and age. Later today I hope to upgrade to a 50-inch LG 4k Smart TV, relegating the ALDI one to the bedroom.
In expectation of necessity I have already registered an LG account, I'll likely need it to set up the new TV properly.
I don't envisage using any of the Smart TV features: those are generally provided (and without intrusive adverts) by the APPle TV 4k unit. I have a soundbar and a pair of 2nd gen HomePods to provide additional audio if the built-in speakers are not as good.
