Teaching with Three Monitors

How can I use Zoom in my classroom with multiple displays, having my students, presentation notes, and presentation on different screens?

This tutorial will demonstrate how to enable Zoom for multiple monitor usage, how to set up your classroom computer (Windows/Mac) and displays, and how to use presentation mode in Microsoft Powerpoint or Google Slides.

You might wonder why you need three monitors. If you teach using the regular in-classroom tech podium, you are already using two monitors—the one in the tech podium and the one projected onto the screen at the front of the class. The third monitor is used to project onto a screen at the back of the room, showing the remote students who are attending in Zoom. This way, you can look at the remote students and it will seem like you are speaking to them because of your eye contact.

Configuring Your Windows Computer

When you log into a campus computer with multiple monitors, you'll be greeted with the BYU-I logo, as well as the start menu, taskbar, and potentially desktop icons.

Open your Display Settings, which you can find from the Start Menu:

When you click on "Display settings," the window that pops up has several important settings you need. Please note that you may need to scroll down to see all of these settings. First, the connected displays and their arrangement. Second, the Identify button. Third, the duplicate/extend menu. These are numbered in the screenshots below:

The displays and arrangement section shows each display, and it gives each one a number. If you have less displays than seems right—for example, if you have two monitors and a projector, but the settings show only two displays- you can click the "Detect" button to bring the missing displays up and add them to this section.

The number overlaid on each display allows you to know which display is which. Just by themselves, however, these numbers don't provide much information. Fortunately, it's very easy to identify the monitors; clicking "Identify" will make the number assigned to the displays appear on that display, as shown in this screenshot:

Lastly, the duplicate/extend menu allows you to determine how the displays will be handled. For the purposes of this tutorial, you want to choose "Extend desktop to [this/all] displays" from the menu. Duplicate will not allow you to use three separate displays for different purposes.

Configuring Zoom

Now that your Windows displays are ready to use, you need to make sure that your Zoom is set up correctly as well. From your Start menu, open Zoom:

You should be signed in to Zoom automatically. If not, click "Sign In," choose "Sign in with SSO," enter company ID "byui," and log in with your BYU-Idaho credentials. Now go to the Zoom Settings:

The Settings menu will have a variety of checkboxes and options, but for this tutorial, you only need two. You'll want to turn on the checkbox labelled "Use dual monitors."  When you turn this checkbox on, it will automatically turn on another checkbox labelled "Enter full screen automatically." It will be easier to move your Zoom windows around, between displays, if this checkbox is turned off. Go ahead and turn it off:


Now, when you start a meeting, you'll be given two Zoom windows—one with participants in Gallery view, and one with meeting controls/chat/etc. You can drag these windows between displays by clicking and dragging the window title and moving it either to the left or right side of the screen.

These Zoom settings are the same on Windows or Apple computers. In other words, you can follow these instructions regardless of which computer platform you are using.

Configuring an Apple Computer

On an Apple computer, click the Apple icon in the top left corner. Choose "System Preferences" from the menu that appears. This will bring you here:

Now you'll click on "Displays". Click the "Arrangement" tab, and make sure that "Mirror these displays" is turned off:

Using Presentation Mode with PowerPoint or Google Slides

Presentation Mode allows you to have your notes on one screen—only seen by you—and your slides on another (usually the projector). Your notes will display on your main monitor. This should be the computer screen at the front of the classroom already. If your notes don't show up on this monitor, you can set it as the main display  from Display Settings. In Display Settings, click on the display that you wish to be your main display (remember, if you don't know which one is which, you can use the "Identify" button.) This will bring up the following checkbox:

Open up PowerPoint, and load your presentation. On the "Slide Show" tab, in the "Monitors" group, select "Use Presenter View":

Now when you present, your slides will appear on a separate display from your notes. Again, if the notes and slides are flipped, all you need to do it set the main display from the Display settings.

You can use Presentation Mode with Google Slides as well. Open up your Google slideshow, which you can find from slides.google.com. Once your presentation is open, you'll go to the View menu and click "Present":

In the toolbar at the bottom, click "Notes," or press "S" on your keyboard to open the speaker notes:

This will open a separate window with your notes. If this window doesn't open automatically as a separate display, you can click and drag the title bar of the notes window to either the left or the right of the screen to move it to a different display.
