Why is material with 'Displacement and Bump' set only showing 'bump' displacement in Cycles? Problem
I am trying to apply a static displacement map to a plane. Even though I am using the Cycles renderer, and I have configured the Principled BSDF shader to use &quot;Displacement and Bump,&quot; I am still not seeing any variation in the plane's geometry.

Windows 10 version 2004
Blender 2.83.0
Cycles Renderer

Cycles Feature Set: Experiemental



Actual Result
It appears that the plane has a bump map effect, but the displacement aspect isn't working.
Expected Result
The plane should have both a bump map and displacement map effect, where the geometry of the plane is being modified by the black and white displacement vector that's being fed into the material output node.
Additional Details
Here's the wood texture I'm using

Here's a preview of the plane. It's flat, despite having the bump texture on it. The displacement isn't actually modifying the plane's geometry, like I'd expect it to.


Here's what my node editor looks like:

Here are my material settings:
Does your plane have enough subdivisions? A flat plane with only one face obviously can't be displaced so you need to add some geometry in edit mode or by using a subdivision modifier before the displace modifier
