A:Answer Most TVs now (any brand) can be hooked up to your wireless router, are 4K, and are smart. An example of Smart is not needing plug ins for roku, Netflix, and many more apps. Think new smart phones like iPhone compared to the older flip phones.
I'll only buy a TV that is smart.
As far as this LG TV, the size is up to you, but find LG TVs has the best sound quality to the point you do not need to buy a sound bar. The blend of picture quality, sound, and price are very good.
