A:AnswerI don't think an internet connection is "absolutely" required. But you will need to connect if you want to use the "smart" features, and get periodic firmware updates.
A:Answerthis for the 48B4 model... there is a right and left part. Look at the stand and it indicates which is right or left. The stand pieces are held in place by 2 screws but you have to slide the stand pieces slightly in to a couple of grooves. When this is done the screws provided will be aligned with the threaded holes going in to the TV. It's easy to miss but not difficult when you look at the parts closely.
A:AnswerThe sound works fine with this TV without a sound bar and there are several options with regard to sound quality. For instance, you can set it to lower the sound for background music and noises.
A:AnswerThe TV does have pre-loaded screensavers, so if you walk away, after a while (you can set how long for them to come on after a certain amount of inactivity), they'll come on. I'm not 100% certain, but I believe you can upload your own photos as screensavers. I haven't looked, but I don't think you can change the background wallpaper. Before I bought mine a few weeks ago, I watched many YouTube videos about this model specifically, and mostly by professional reviewers. You could check them out for more detailed info, and perhaps leave a question in the comments box. A few got back to me pretty quickly.
A:AnswerHopefully, this is helpful: Yes, the LG B4 OLED TV does support Auracast. LG has confirmed that Auracast is available in their 2025 OLED TVs, including the B4 series. This feature allows for one-to-many audio broadcasting, enabling multiple users to connect headphones or hearing aids simultaneously for shared listening.
