Hi,
Used texture map for displacement but circular lines are coming.... any idea how can I fix this....?
Thanks.

URGENT please....!
I am in middle of the job....!
Thanks.

This looks like not enough information in the displacement map. Is it saved to 8 bit format?
-
yes... created in Photoshop 8 bit, have to increase to 16....?
I will give a try.
Edit:
I tried 16bit.... but same in render view. I photoshop zoom, I am not seeing any lines or bands, from where these are coming no idea....?

When you increased the file to 16 bit, did you redraw the gradients? I believe if the gradient already has 8-bit banding, the banding would still be there unless you recreate the gradients from scratch in the new workspace.
Also, might blurring the displacement map slightly help reduce gradient artifacts?
-
Even if you convert your bitmap to 16 or 32bit you will always be limited by the original 8bit data. Let's say you have a 360° panorama, converting the image in 32bit will not give you an HDR for free;)

As others already said, simply converting from 8 to 16 bits, will not gonna help. If you don't have an option to recreate map in 16 bits from scratch, simple gaussian blurring might help. I find that for 4K maps, 8 px blurring gives optimal result.
