Underscan slider missing after 10.13.2 Update

I have returned to my Mac Mini today after the 10.13.2 High Sierra update overnight. My mini is connected via a KVM switch to a 42" monitor. Prior to the update I had to set the underscan so that it would appear on the screen correctly. The update seems to have fixed my underscan issue but I now can't turn it off.

Is there any way to set underscan (probably back to zero) when the slider option doesn't exist any more in display preferences?

Mac mini (Late 2012), macOS High Sierra (10.13.2)

Didn't work for me on my Macbook Pro. The underscan bar still doesn't show after updating to Sierra.

What external monitor and connection are you using...?

FWIW were are working on Mac Mini's here, so perhaps you should also post over in the MacBook section of these forums.
