Difficult to answer without an example but if your pixels blurr?

In the displacement map image_map set texture filtering to none.
For Poser9 / PP2012 set is to crisp

In the firefly render settings set MSR to 0.2

Also check image dimentions:

512x512
1024x1024
2048X2048
4096x4096 (the Max Poser can handle for a single texture)

Anything in between will cause additional blurring.( interpollation of the pixels)

Displacement maps can be VERY sharp in a rendering.
