Screen sharing allows hosts and speakers to present their screen to attendees during a live event.
Note: Screen and media sharing from the stage can only be done via the Media Tray - not from the Studio. For information on sharing media from the Studio, see our separate guide for hosts and co-hosts.
The Media Tray is located to the left of the AV controls, below the Gallery.
Speakers, crew, and moderators do not have access to the Studio’s media section
Instead, they (along with hosts and co-hosts) can upload and share media directly from the Media Tray
If a host or co-host shares media from the Studio, anyone on stage with permission can take control of that media
Start Screen Sharing
On Chrome, Edge, or other Chromium-based browsers
Join the event studio.
Click Share in the Media Tray located on the bottom toolbar.
Choose what you want to share:
Entire Screen – shares everything on your monitor.
Window – shares a specific application window.
Browser Tab – shares a single browser tab.
Select your screen, window, or tab.
Click Share.
Your selected content will appear in the event for attendees.
In the media tray, there is also a setting that allows anyone on stage, including attendees, to share media via the Media Tray. The host can choose between these two options:
Hosts & Speakers allows on-stage speakers can also control the active media
Anyone on stage allows on-stage users to share media, including attendees.
How to Share Computer Audio
When sharing a browser tab or screen, you may have the option to include audio from your computer.
To share audio:
Click Share. If there are existing items in the media tray, you'll select New Share.
Choose what to share (Chrome Tab/Window/Entire Screen).
Enable Also share tab audio if available.
Click Share.
Important
Browser tab audio is generally the most reliable option.
Some browsers or operating systems may not support system audio sharing.
If attendees cannot hear your shared audio, stop sharing and start again while ensuring audio sharing is enabled.
How to Stop Screen Sharing
There are several ways to stop or minimize a screen share during an event:
From the Media Tray
Hover over My Screen.
Click the three-dot menu (...) and select Stop Sharing.
To Minimize the Screen Share
Hover over My Screen in the media tray.
Click Minimize.
From the Stage
Hover over the screen share on stage.
Click the arrow icon in the top-right corner to minimize it.
To End the Screen Share from the Stage
Hover over the screen share on stage.
Click the X (Stop Sharing) icon.
Once screen sharing is stopped, your camera feed or previous stage layout will resume automatically.
What Attendees See
When screen sharing is active:
Attendees see the shared screen in the main presentation area.
Hosts can continue speaking while sharing.
Other speakers can remain on screen depending on the selected layout.
Chat, Q&A, and engagement features continue to function normally.
Adjusting Layout (Focus Mode)
You can change how the screen share is displayed using Focus Mode. Available options include:
Split
Large
Fill
Solo
To adjust the layout hover over the screen share on stage and select a layout option.
Troubleshooting Screen Sharing
Screen Share Button Is Missing
If you do not see the Share button:
Refresh the event page. Good news - you're event will not end when the host refreshes.
Make sure you have joined the event as a host or speaker.
Ensure your browser is up to date and screen sharing permissions are enabled.
Try using Google Chrome for the best experience.
Screen Share Starts but Attendees See a Black Screen
This can happen when:
Sharing protected content (such as DRM-protected video).
Sharing certain applications that block screen capture.
Graphics acceleration conflicts occur.
Try:
Sharing a browser tab instead of an application window.
Sharing your entire screen instead of a single window.
Restarting your browser.
Screen Sharing Permission Denied
If your browser or operating system blocks screen sharing:
macOS
Open System Settings.
Go to Privacy & Security → Screen Recording.
Enable permissions for your browser.
Restart the browser.
Windows
Check your browser permissions and any security software that may be preventing screen capture.
No Audio During Screen Share
If attendees cannot hear audio from your shared content:
Confirm audio sharing was enabled when starting the share.
Try sharing a browser tab instead of a desktop window.
Verify the audio is playing through your computer.
Stop sharing and restart the share with audio enabled.
Screen Share Appears Blurry
For the best quality:
Use a wired internet connection when possible.
Close unnecessary applications.
Share a browser tab when presenting web content.
Avoid scaling your operating system display excessively.
Use a modern version of Chrome.
🔁 Infinite Mirror Effect (Expected Behavior)
If you share your entire screen while viewing your event, you may notice a repeating “infinite mirror” effect.
This is normal behavior, not a bug
Your audience will only see the intended shared content, not the mirror effect
Recommendations for Hosts
For the best screen sharing experience:
Use Google Chrome whenever possible.
Close unnecessary applications before going live.
Test your screen share before your event begins.
Share a browser tab when presenting slides or videos.
Share audio directly from the tab when playing media.
Have any presentation materials open and ready before starting the share.
Use a second monitor if available to monitor the event while presenting.
Run a practice session before important events.
