high sierra overscan issue

posted on this a few days ago, no support/fix

found another post with multiple reports on this issue dating back to october 2 and yet NO posts on a fix

(The specified item was not found.

so, fresh post... anyone have a fix for those of us who have NEVER had an issue with overscanning on macs before the 10.13.1 update?

(10.13.1 on mac mini (late 2014))
