A sneaky way to add a second screen to use PowerPoint Presenter View in Teams (Mac) with 1 monitor/screen

The problem

PowerPoint Presenter View is popular because it allows you to share your slides with the audience when connected to a projector or TV and you see your speaking notes. You can also access some of the expert features of Presenter View like jumping seamlessly to any slide, drawing on the slide, or zooming in on the slide while presenting (not all of these features are available on the Mac yet but you can learn more about the expert features in this article).

Presenter View works best with two screens, which is what is was designed for. The problem is that when people started working from home, they brought the corporate laptop home and have limited space. No second monitor or screen means you can’t use Presenter View like you did in the office.

The best 1 screen solution

When you display your slides full screen in Slide Show mode you can actually switch to Presenter View and share the hidden Slide Show window in the Zoom meeting. This way your attendees see high-res slides while you see your notes and have all the expert features of Presenter View. You can watch how to do this for Windows and for the Mac.

Other 1 screen solutions & potential downsides

In the past, Teams did not have any option to share just your slides if you had one screen on a Mac. PowerPoint has a hidden slide show window when it is running Presenter View Preview with one screen and in the past Teams would not reliably show this hidden window when sharing a window in a meeting. In my testing for this article (mid-February 2021), it seems like I am having success now sharing this hidden window in a meeting. The problem is that this method relies on a hidden window being recognized by Teams and it could break due to an operating system or Office update.

A hardware-based solution I published is to use a video capture device to create a “virtual” second screen on a Mac. Then you can use the normal two-screen Presenter View with all the features. This does require a video capture device, an HDMI cable, and an open USB port on your laptop. This may be bulky for a tight home work setup, requires a driver to be installed on your laptop, and you may not have a free USB port on newer laptops that may only have two ports.

The best solution I’ve found so far to add a second screen

Since Presenter View is natively built to use two screens, I’ve recently discovered what I think is the best solution I’ve come across so far to add a second screen. It is to create a “virtual” second monitor using a Virtual Display Emulator Plug. This small HDMI device makes your laptop think that you have a second monitor attached. Then you use Presenter View as you would with two monitors and share this “virtual” second screen in Teams. Because it is a hardware solution that does not require any drivers to be installed, it should be safe in almost all corporate IT environments.

What is a Virtual Display Emulator Plug

This device is also sometimes called a ghost monitor. It is used to make a computer think it has a monitor attached when it doesn’t. You might be asking, Why would anyone ever use this? This device is used in industrial situations for control computers that control machinery and do not have monitors. It allows technical staff to remotely connect to the computer and have a high resolution display of the processes that the computer is controlling. Without this device, a computer may not run properly or only allow a very low resolution default display which makes it hard to work with when accessing it.

It is a very small device that has an HDMI connector at one end and a small chip at the other end in a small enclosure. The chip emulates a high-res monitor. Here’s how small mine is compared to a quarter.

You can buy these plugs online. I got mine from a supplier of technology to the mining industry, showing how these plugs are used primarily for industrial purposes – at least up to now. You can get them through Amazon as a single plug, a two-pack, three-pack, or six-pack.

Connect the Plug to your laptop

To create a “virtual” second monitor with this plug, simply connect it to the HDMI port on your laptop or connect it to the adapter you usually use to connect an HDMI screen or projector to your laptop. I use the Apple USB-C to HDMI adapter that also has a USB-C power pass-through and a USB-A port.

Check the second display in the Mac OS

After you have connected the plug to your laptop, check the Display Settings. On the Arrangement tab you should see two displays now connected. On this tab make sure that the Mirror Displays checkbox in unchecked so that the desktop is extended on to the ghost monitor. You can click on a monitor in the arrangement and a red rectangle will appear on that screen so you know which screen is on which side. You can rearrange the monitors by dragging them if needed.

By default the Mac OS puts the Display Setting window for each monitor on that monitor so you lose the settings window for the ghost monitor. Click the Gather Windows button in the lower right corner of the Display Setting window on your laptop screen to bring all the Display Setting windows to the laptop screen.

You can click on the window for the ghost monitor and use the Resolution: Scaled option to set the display resolution if needed although the default usually perfectly fine. Depending on what plug you have, it may list different resolution options. As long as you select 1280 x 720 your slides will be clear to the audience. If your plug defaults to 1920 x 1080 that will work fine as well. You may want to consider the lower resolution if your attendees are using slower connections or cellular connections. Resolutions higher than 1920 x 1080 will not give the audience any better of an image and will slow down the display of your slides resulting in a poorer experience for the attendees (this article has more suggestions if attendees are using slower connections).

Set up PowerPoint to use Presenter View and a second screen

Now that your laptop thinks it has a second screen, you can set up your PowerPoint file to use Presenter View and select which screen the slides should be displayed on. In PowerPoint on the Slide Show ribbon, click on the Set Up Slide Show button to open the dialog box. In the Monitors section use the drop-down list of monitors to select the ghost monitor (usually called Monitor 2) as the monitor to display the slide show on.

Start Presenter View

Start your presentation in Slide Show mode using the Presenter View button on the Slide Show ribbon.

You should see Presenter View fill your laptop screen. You can confirm that there is a second screen showing the slides by clicking on the Swap Displays button in Presenter View which swaps the Slide Show and Presenter View between the laptop screen and the ghost monitor.

When viewing the Slide Show on the laptop you can return to Presenter View by clicking on the three dots in the lower left corner of the slide and selecting Swap Displays in the menu that appears.

Share second screen in Teams

Use Command+Tab to return to the Teams window since Presenter View takes up the entire screen. In Teams, share the second screen, the one with the slides being shown full screen. Here’s what the Teams sharing dialog would look like (Screen #2 would be shared).

Deliver your presentation using Presenter View

Once the audience sees the screen with your slides, you can start delivering your presentation using Presenter View. Don’t forget that Presenter View has some features that you make great use of in virtual presentations.

When done, end the presentation and disconnect the plug

Since PowerPoint thinks you have a second screen connected, end your presentation the same way you would if you had a physical second screen. Stop sharing the screen in Teams, end the meeting, and disconnect the plug. In most cases the next time you connect the plug the laptop will recognize the plug as a monitor that has been connected before and extend the desktop so you are ready to go.

Moving an app window from the ghost monitor

You can share more content than just PowerPoint slides, including websites or other apps like Excel or Word. If one of these apps accidentally opens on the ghost monitor, how can you move it back to the laptop screen? Right-click the app icon in the dock. Click on Options. Click on Desktop on Display 1.

The window will now be displayed on your laptop screen.

Why I think this may be the best solution to add a second screen for those with just a laptop screen

Here’s why I think this is the best solution so far:

  • This is the cheapest solution since the virtual display emulator plug costs about $10
  • It is a hardware solution that does not require any drivers to be installed so it is likely to be highly compatible with locked down corporate laptops
  • The plug is very small and takes up less space than the other hardware solution I published
  • Because your laptop thinks it has a second monitor, you can use all of the features of Presenter View when presenting without having to remember to pause and resume your screen sharing
  • This solution does not rely on a hidden window that may not be available in the future
