As I understand it Poser and Daz handle displacement maps totally differently. Poser looks at bumps and displacement as a flat surface that does not indent. So dead black is the base and lighter shades of gray to white move up. In daz middle gray is the flat plane. Anything darker is seen as indented while anything lighter gray is seen as pushing up. In addition poser file settings generally come into daz set way to low. You should raise them to 100% and see how that looks. You may also have to play with the + and - some to get the proper depths.  In the long run daz has a more flexible system than poser but most files are created for poser not daz.
