I've got this issue with OSX El Capitan. My existing monitor show black border in resolution 1920 x 1080. The black border is shown only on left side of monitor. This never happen previously in Yosemite.

What I've tried but didn't work:

  • set resolution in safe mode
  • unplug and plug again my mini to VGA cable
  • Restart
  • play with my monitor setting (reset setting)

Here is the screenshot:

Same problem with my Acer monitor. I've researched a lot online. Next few days my ordered VGA-DVId will test my last resort. So I suggest you might change your monitor's input to DVI. This solved the issue for me.
