Screen Sharing
Presenters can share their screen, an application window, or a browser tab with all participants. Screen sharing works most reliably on desktop devices using a current Chromium-based browser.
Starting Screen Sharing
Click the screen sharing button in the toolbar (monitor icon). The button appears grayed out when inactive and turns blue when active.
Your browser will open a sharing dialog where you choose what to share.
Select one of the sharing options (see below) and confirm.
Sharing Options
| Option | Description |
|---|---|
| Entire screen | Shares everything visible on your screen. If you have multiple monitors, you can select which one to share. |
| Application window | Shares only a specific application window. The application must already be open. |
| Browser tab | Shares only a specific browser tab. Available in Chromium-based browsers. |
Sharing Computer Audio
When starting screen sharing, you can optionally enable audio sharing to transmit your computer's system sound to all participants. This is useful when showing videos or audio demonstrations.
Look for the Share audio checkbox in the browser's screen sharing dialog to enable system audio transmission.
Stopping Screen Sharing
There are two ways to stop sharing your screen:
- Click Stop sharing on the floating toolbar that appears after you start sharing.
- Click the blue screen sharing button in the BigBlueButton toolbar again.
While screen sharing is active, the shared content replaces the presentation in the main display area for all participants. A button to enlarge the shared content is available at the top right.
Screen sharing on smartphones and tablets may be unavailable or limited depending on the browser and operating system. Safari support varies by version and platform. For the best experience, use a desktop computer with a Chromium-based browser.
Before sharing your screen, close unnecessary tabs and windows to avoid accidentally revealing private information.
