How can I play a presentation on a shared display without losing my speaker notes?

Aim for a presentation mode that separates your presenter view from the audience’s slide display. In PowerPoint, Presenter View is designed to show notes on one display while the audience sees slides on another. Microsoft describes using two displays and extending the Mac desktop for this setup. [S1]

In Google Slides, you can open Presenter view and use its speaker-notes panel. [S2] The exact controls and behavior depend on your app and display arrangement, so treat this as a setup to test rather than a guarantee for every room.

Start with the app’s Presenter view and a separate-display arrangement if your device and room setup support it. That matches the two-display approach Microsoft describes for PowerPoint. [S1] Don’t assume that another option, such as mirroring or casting, will keep notes private. The supplied guidance does not establish that those methods behave the same way across apps and devices.

Before the audience arrives, open the presentation and check both screens: your device should show the notes you need, and the shared display should show only the intended slides. If the setup gives you no way to verify the audience view, use a tested alternative or present without sensitive notes.

Don’t rely on that without testing. Google’s guidance describes casting from Android and says notes can be shown or hidden on the device, but it does not establish that notes remain private from the TV in every casting setup. [S2] If possible, test with the actual display: open the notes panel, start casting, and check what appears on both the device and the TV.

If you cannot verify the audience view, hide or remove anything sensitive from the notes and choose a presentation method you have checked. The notes controls alone are not proof of what the shared display will show.

Rehearse the complete path you plan to use, not just the slide deck. For example, use placeholders rather than real room details:

1. Open [presentation app] and [test deck] on [presenter device].
2. Connect to [shared display] using the planned method.
3. Start Presenter view or the app’s equivalent.
4. Confirm your device shows a test note such as NEXT: introduce the project timeline.
5. Confirm the shared display shows the slide, not that note.
6. Advance one slide, then exit and restart the presentation once.

Check the audience display from the audience’s position if practical. Include the opening, a slide change, and the exit in your checks; confirm they don’t reveal material you meant to keep private. These are rehearsal checks, not guarantees about every device, app version, or casting configuration. If you cannot confirm what the display shows, use a different tested setup or keep private information out of the notes.
