How to Manage External Displays Connected to Your Chromebook

With recent updates, Chrome OS has added support for managing additional monitors connected to your Chromebooks and Chromeboxes. The UI is simple, and options straight forward. Let us take a look.

Managing External Monitors on Chromebook

Open chrome://settings/display on your Chromebook to get access to the menu where you have all the controls for external displays.

You can select the display that you wish to make changes to and use additional options provided below to modify things. Here is a list of things you can control.

  • Mirror as a secondary display or make it primary
  • Change resolution
  • Change orientation. Available options are Standard, 90, 180 and 270 degrees
  • Adjust Overscan (Overscan is extra image area around the four edges of a video image that may not be seen reliably by the viewer, says Wiki)

So those are the basic controls you get on your external monitors on a Chromebook. Here is a screenshot of this screen. This is from my Chromebook without connecting an external display. So, you will see most of the options disabled.

  1. My “Manage displays” screen does not give me the options to change resolution, orientation, or overscan settings. I do have my Chromebook mirrored to a TV via HDMI cable, but it would be great to try out different resolutions to see what looks best. (I have the Samsung Chromebook.) Is there something I need to do to get an update that will allow these setting changes? Thanks!
