Micropolygon displacement uses  adaptive subdivision to displace the geometry at the time of rendering only , there is no microdisplacement map, it just use displacement map with automatic ( adaptive subdivision), the details in front will create higher resolution of the geometry and the details in back lightweight geometry like you have with LOD, resulting in less usage of memory and faster rendering , the settings should be available under subdivision setting of the model you using it for where you can choice if you want to use Adaptive subdivision , the result of it will be visible only in a render It is a great feature for many reasons especially if you use it for environmental renders like detailed ground planes or high details of a close up models, it also prevent clipping and fuzziness in animations . Micropolygon displacement doesn't do visually things much differently than a regular displacement, but what really matters here is the adaptive subdivision and the lower usage of memory that are so precious especially when you use GPU for rendering

I don't think that we would find this in the material room, more likely in the render settings. But I haven't seen that either.
