Want a 55-inch smart TV or standard TV? We recommend TVs this size for medium-sized to large living rooms with a viewing distance between 2.5 and 3m. There's a large assortment of 55-inch televisions, from 4K TVs to advanced OLED models. With an OLED TV, you can enjoy deep black tones and a bright contrast because the pixels light up and dim individually. That way, movies and series look vibrant.
