Display problems on my Mac mini
I recently upgraded my Mac mini to OSX Mavericks 10.9.2. On my Dell monitor, there appears to be a 'black border' surrounding the desktop instead of it fully fitting to screen. I've looked in System Preferences but there isn't the Underscan slider for me to maually scale the display, but when I connect it to my LG TV, this 'Underscan' option is available. Prior to upgrading to Mavericks, it was perfect. I'm just wondering if the display settings have changed in Mavericks and if people have had the same problem.
Thanks
