File Texture Aliasing Issue for Displacement Map in Arnold

I created a displacement map in Photoshop and when I render with Arnold, I get these striations in the transitions. This is causing it to look blurry when zoomed out, and all the extra, unnecessary detail is causing issues when rendering. I have tried messing with the file texture filter attributes but I don't really know if this applies when rendering with Arnold, or what settings to try. I have also tried converting displacement to geometry but I lose the shape of the displacement I was going for. Any suggestions would be appreciated.

It could be your settings.

your displacement map needs to be higher bit depth
you're probably using a 8 bit integer texture
needs to be 16 bit float or 32 bit float

If you want to send me your file, I can have a look. Filtering was the first thing I thought of too.

Have you tried the Deform > Texture? I get predictable results using that.

Maybe one of the lights?

It shouldn't blur when zooming out, try adjusting the texture filter.
