Medium-sized TVs are televisions with an image diagonal between 40 and 55 inches, or between 102 and 140cm. These televisions are available with Full HD or Ultra HD support. The selection of medium-sized TVs ranges from basic Full HD 43-inch models to high-end 55-inch 4K televisions. To make the right choice from this range, you look at the sound and image quality and the resolution, for example. Most medium-sized TVs have smart TV functions so you can access apps such as Netflix and YouTube.
