Using multiple displays (docking stations, projectors, secondary monitors) with Chromebooks: mirror, extend, and orient displays as well as changing the zoom (sizes of everything) level.
Getting to Display Settings
Click on the time in the bottom right corner
Changing the Display Size (how big and small items appear)
If things are appearing too big or too small on your screen, such as on a smartboard display, you can change the zoom level to make everything appear larger or smaller.
Once in the display settings click and drag the slider next to Display size to increase or decrease the size of items on the screen:
Mirror Chromebook on second display
To mirror (both your monitor and Chromebook will have the same screen) check the box.
To extend (you can drag windows between them as two separate monitors), un-check or leave it unchecked
Setting a different primary display (Docking station setups)
By default, the built-in (Chromebook) display is the primary display. To change this, click the secondary display and then use the dropdown menu next to ‘Screen’ to change it to ‘Primary display’.
To change back, go to the non-primary display (in this case, now, the ‘built-in display’) and use the dropdown menu to select ‘Primary display’.
Orient Chromebook display with second display (Docking station setup)
The blue highlighted box shows which display you have selected below the image (in this case, the ‘built-in display’ aka the Chromebook display).
Click and drag the box into the position around the second box (docking station monitor) that makes sense for your setup.
The red arrows in the examples below indicate which directions windows will need to be dragged in order to move them between the primary and secondary displays. In this case, the small box is the Chromebook display.
