When sharing a full-screen presentation in applications such as Keynote, Powerpoint, or Google Slides with Highfive, there are a few things to keep in mind. Because of the way these applications work, it is not always straightforward to share a single window with only the presentation showing.
Note that these instructions only apply if you’re using any of the presentation software mentioned above. Sharing a window from any other application will work as you would expect.
With screen sharing window selection, sharing a full-screen presentation isn't as straightforward as one would expect because the original presentation window you are working in when you click the “Start Presentation” button in Powerpoint or Keynote is different than the window that is actually showing the presentation.
What this means in practice is that you may have to start the presentation before you select the window to be shared in the Highfive application, depending on the presentation software you are using.
In the case of Keynote on Mac, the second window that is created when starting a presentation is not recognized as a real window by the macOS operating system. As a result, the second window won’t show up in the Highfive screen sharing window selector.
How To Share A Full-screen Presentation
The only way to share a full-screen Keynote presentation is to click on the Share Screen button and use the Entire Screen option when presenting.
The reason you cannot use Highfive to select the new window that gets created by Keynote (which actually displays the full-screen presentation) because it is not recognized as a real window by the macOS operating system. Therefore, it will not appear as a selectable window when we ask the macOS operating system for all the windows you can share.
Powerpoint (Windows and macOS)
If you are using Powerpoint (both Windows and Mac), you will be able to present and share a full-screen presentation:
- Open your presentation in Powerpoint.
- Select the Slideshow tab and begin your presentation at the desired slide.
- Navigate back to the Highfive application by using Alt-Tab (Windows) or Cmd-Tab (Mac).
- Select the Share screen button.
- Select Pick a window.
- Select the full-screen Powerpoint presentation application window.
Google Slides or other web-based tools (Safari)
Safari will open a separate screen when you click the “Present” button that is not reported as a selectable window by the operating system, so the only way to share a full-screen presentation is to click on the Share screen button in the Highfive application and then select Entire screen.
Google Slides or other web-based tools (Chrome)
Chrome opens the presentation in the same window as the browser, so if you share a single window, it will work as expected. You don’t have to do anything except pick the window that contains your presentation.
Google Slides or other web-based tools (Internet Explorer)
Internet Explorer will open a separate screen when you click the “Present” button that is not reported as a selectable window by the operating system, so the only way to share a full-screen presentation is to click on the Share screen button in the Highfive application and then select Entire screen.
Google Slides or other web-based tools (Microsoft Edge)
Sharing individual windows is currently not supported with Microsoft Edge. Click on the Share screen button in the Highfive application and then select Entire screen instead.
