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))
Mac mini, macOS High Sierra (10.13.1)
The same overscan issue occured after installing High Sierra update when using a Mac mini set up and a HP 23xi monitor. I've found the solution is to use the HP monitor controls (the bottom right buttons found on the monitor itself). Go into menus and find Image Control then Custom Scaling to switch the Overscan control from Auto to Off.
There doesn't seem to be a solution to be found from within the Apple software though a workaround is to go to Settings each time you logon, then to Resolution and select Scaled. Then select 1600 x 900 (which corrects the dimensions) and then select 1080p.
While this works for HP23xi and Mac mini (2012) it may be different for other monitor set ups, but if possible try addressing the display problem through the monitor's own controls and not the Apple software.
Same issue here. Still no fix as of Feb '18.
