    Click the box next to "Mirror Display" if you want to exactly mirror what's on your Windows/Mac screen on your Chromebook. You can also leave this blank if you want to treat your Chromebook as an extension of your computer's monitor so you can drag and drop stuff to the right or left of your main screen.
    • You can adjust the Retina (macOS only), Framerate, and Quality settings.
    • You are done, after you make these adjustments. Your Chromebook should be acting like a monitor for your computer. When you are finished with Duet, close the program window from your Windows/Mac computer first so you can view your Chromebook and close the app.
    • If you are having trouble connecting Duet to your Chromebook, you might need to select Connect to IP Manually . To get your Chromebook's IP address, go to Settings > Network on Chrome OS and click the network you're currently connected to. Towards the bottom of the page, you'll see a series of numbers and periods next to a section called "IP Address." That series of numbers and periods is what you'll copy and paste into the Connect to IP Manually field.

      • Right-click your Windows desktop and select Display Settings . Select Extend these Displays under the "Display" header and click Apply . Now, your Chromebook will be an extension to your Windows monitor.
