Facing and issue with displacement map

Hey everyone
I am quiet new to using unreal engine 4 and I am facing an issue with displacement map in the engine. When i bring my height map into material editor and apply it to my mesh, my mesh seems very distorted on the edges. I am uploading a screen shot of both my viewport render and my material editor.

You need more resolution/tessellation to reduce those artifacts. POM would probably be a better alliterative to displacement for that asset.
