Choosing a TV mainly depends on image quality, sound quality and function. Generally, a 32-inch TV is placed in the bedroom, and there are two options. First, because opening digital signals requires a set-top box and installing a second set-top box at home requires an extra charge, you can choose network TV or digital all-in-one machine, which can save a lot of trouble. Second, you can mainly watch TV, and you can choose a mid-range model with few functions but good results. As for USB, I think, don't ask too much.
