Displacement changes the vertexes of your object using a grey scale image and creates a real surface based on the image you are using. The more detail the picture is, the more detailed your object will be. For your Displacement to work well, you have enough vertices / polygons of your object. The advantage of this parameter is that it creates extremely realistic surface indents. When you look at the camera from any angle, your object will look detailed in every sense. Unfortunately, every good thing has a price: Displacement is a process that requires a lot of computation and Vram. So, use it carefully.
