Want a new 40-inch OLED TV, or a 55-inch one? We recommend TVs of this size for medium-sized rooms with a viewing distance of 2 to 4m. An OLED television has pixels that light up and dim individually, without LED backlight. This way, you can enjoy realistic images with a powerful contrast. Black parts of the screen are truly black and every color tone is visible. Your favorite movies and series look realistic.
