Video walls
Video walls are made of smaller LCD displays (nowadays standard is 49" and 55" in format 16.9) forming bigger screen area, in bigger resolution (smaller displays resolution are added up). Thus, large screens of different shapes can be made in different formats, for example: 2x2, 3x1, 2x2, 3x2, 3x3, 4x2, 4x3, 4x4, 5x4 ... 10x2 and more).
