Question: 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?
