I have a MacBook Pro with Touch Bar. I plugged in my external 1080p display (HP 25bw) in clamshell mode and it almost works great - except the screen is too large for the monitor. My dock is too far down off the edge, and my menu is too far up.

For example, when I took the attached screenshot, the Chrome window fills the entire screen I can see:The chrome window is all I see

I have checked and the display options are using native resolution of the monitor (1920x1080 @60hz).

Does anyone have any suggestions for me? Thanks so much.

Note: For any with this same monitor model in the future, thanks to @bmike I found the steps for disabling overscan for this particular monitor model here: https://discussions.apple.com/thread/4994857?tstart=0

Typically this is an issue when you connect over HDMI and the display / TV / monitor settings can be adjusted to turn off or reduce the “overscan” which in effect is zooming in in the center of the signal.

Search here for overscan and you’ll see a lot of results:

Specific steps for HP 25bw monitors are as follows:

  1. Press the Menu button to open the OSD settings.
  2. Scroll to "Image Control..." and press OK.
  3. Select "Custom Scaling" and press OK.
  4. Select "Overscan" and press OK.
  5. Select "Off" and press OK.
  6. Select "Save and Return" until the OSD menu closes.

Same steps will work for MacBook Pro 2018 connecting to HP Pavilion 25xi.

  • Excellent, thanks! I wasn't aware of the term "overscan". Your answer led me to being able to find the steps for disabling overscan on my monitor and now it works perfect. I'll accept in 5 minutes when the system lets me do so. – malexdev Sep 3 '17 at 15:46
  • Perfect @gearheadalex Please edit my answer with details on what the fix was - buttons to press or terminology on the display menus or a picture. That will help lots of people going forward. Cheers and thanks. – bmike Sep 3 '17 at 15:49
