So I have a 2010 Macbook Air, 1.6GHz, and I am trying to hook it up to an external display, this Insignia:


I have an HDMI -> MiniDisplayPort cable from Amazon that I've connected. In both closed clamshell mode and extension mode, a tiny bit of the screen on all four sides is cut off from the monitor -- the entire top menu bar is cut off, and a bit of the bottom dock is cut off. The settings in Display Preferences is 1080p. I've tried holding alt, and I do not see any listing for 1920x1080 -- I only see 1080i, and lower resolutions, none of which fix the problem of the menu bars being cut off. Could it be the HDMI -> MiniDisplayPort Cable? I've ordered a Male VGA -> MiniDisplayPort and will try that, but in the meantime, does anyone have any other ideas?

    Have you tried changing the settings on the TV? Does it have an overscan setting?

In the display settings on your mac for the tv, is there a slider for "Underscan"? That's what allowed me to shrink the picture down a bit so the corners weren't cut off as much.


As @xpereta indicated, you are suffering from overscan. Unfortunately not all TV's let you disable overscan. Sometimes they will, but they won't call it overscan - does your TV have a "PC" or "Game" mode? If so, setting the input you have your Mac plugged into to one of those modes should turn off the Overscan and should thus eliminate the clipping you are seeing.

  • setting my TV to Game mode worked for me, I am using Windows 10 and insignia TV 56 inch. thanks much! Commented Jul 2, 2019 at 7:12
