Material with displacement

Hi I finaly ceate a displacement material, but it applies itself on different way depend 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
