Displacement tesselation question

Hi I create a displacement material, but it applies itself on different way depending the object; on the screenshot you can see the tesselation on the sphere is high but on floor and on the plane its lighter the tesselation is low even if I modify the parameter in the material, do you know how can I fix that? I post 3 screen shot one with the lit preview one with the wireframe and one with the material nodes, if it can help or if you know how can I modify the tesselation for floor and the plane it would be great…
thanks alot
