It would be useful to know what you already got for the job.
You probably tried other settings for Displacement than what's default in the render settings?
You got a proper, custom-made and hi-resolution displacement map that's not a JPG and preferably 16 bit or more?
Is it for an animation or for a still?
And - what's currently wrong you would want to have better?
I used screen size 0.5 with hi-res B&W texture, lines and edges was not smooth. It was still and very closeup camera view.
I saw Corona displacement tutorial... used same technique but I was not getting result which I was needed. If any special setup for that.... please would like to see that.
@burnin: I was also doing bitcoin...!
Thanks.

Sorry if I repeat myself, but most problems I have seen with displacement come from the used maps.
Your displacement map is not a JPG or something lossy, it's a TIFF or something else in a lossless format with 8 bits per channel (or better 16 or even 32)?
And the resolution was big enough to give enough information to the rendered parts of the image with your chosen render resolution? So, if you use your displacement map in the Diffuse channel everything looks smooth in the rendering (with no sampling for the texture in Diffuse to get the real deal)?
Sometimes a little smoothing (blurring) of the texture helps, but only if it is hires enough and you might lose details nevertheless, of course,
