Note: this Solutions Doc assumes that you have connected your Chromebook to your projector using an HDMI cable or HDMI to VGA adapter. If you need help with this go here: https://help.bhrsd.org/support/solutions/articles/28000013320-connecting-a-chromebook-to-a-projector


Getting the Projector to Match Your Chromebook Screen


When you first connect your Chromebook to your projector it may display in extended mode (the projector acts a second monitor). This means the projector will show an additional desktop rather than the same one you’re viewing on your Chromebook. In this mode you can drag a window to the right and slide it on to the extended display.


Most teachers, however, use mirrored mode, which shows a mirror image of whatever is on your Chromebook’s screen. To enable mirrored mode do the following:

  • Hold Ctrl and press chromeos_full_screen on the keyboard.


This will now mirror your Chromebook’s screen to the projector.



Special Notes: TestNav & Display Settings


Note: If you are trying to use an application that uses KIOSK MODE (like TestNav for example), you need to adjust the display settings BEFORE launching the kiosk app. Do this by logging into the Chromebook as you normally do, then log out, then launch the kiosk app.


Note: If your projector and Chromebook do not share a common resolution you may notice that your screen shrinks or displays black borders. This is normal.


To access more display settings ( resolution, orientation, TV alignment, primary) enter the following in your browser and hit RETURN:

  • chrome://settings/display

You can also set your displays to mirror from the settings/display panel.
