Share Screens and Videos

Share your screen, desktop, or other content during a meeting, even while your video is on.

• The host can set default options to disable participant's ability to share or annotate on shared screens in their account Meeting Settings, or on a per meeting basis during the live meeting using the Security icon on the meeting toolbar. 
• The host can give slide control to other participants by using the Slide Control icon on the meeting tool bar.
• Start sharing after you have joined the meeting; or, launch a meeting with shared screens already open.

The Share Screen button is located on the meeting tool bar, click to begin the process. The ^ icon opens a selection of who can share.

Basic and Advanced Screen Share Options:

Basic

Share your entire desktop, specific application windows, whiteboard, or iPhone/iPad screen. When using 2 monitors they are identified as Screen1 or Screen2, only the content that is open on the selected Screen will be shared. 

Advanced

• PowerPoint as a Virtual Background: Allows you to utilize a slideshow presentation as your virtual background.
• Portion of a Screen: Share a portion of your screen represented by a green border. Portion size can be adjusted.
• Computer Audio: Share audio from the computer without sharing screens.
• Video: Share video content from your local device.
• Content from a 2nd Camera: Share a secondary camera connected to your computer; for example, a document camera or the integrated camera on your laptop.

Additional options found at the bottom of the Share Screen window:

• Share Sound: Share sound in video along with shared video.
• Optimize for video clip: Check this if you will be sharing a video clip in full screen mode. Do not check this otherwise, as it may cause the shared screen to be blurry. This should be enabled/disabled before and after the video you wish to play.
• Share to breakout rooms: Allows the host or co-host to share their screen from the main session directly into all open breakout rooms. Any active shares in any breakout rooms will be interrupted for the host's/co-host's shared screen. Annotation or whiteboard is saved before the host's shared content is viewed.
• Meeting hosts can broadcast their microphone audio to all breakout rooms in a meeting. Previously, only device audio could be shared to breakout rooms from the main session.

When you have clicked on the Share button on the bottom right of the Share Screen window, the sharing process is started. Once 80% of devices acknowledge receiving the shared screen, you will see a notification banner stating 'Participants can now see your screen'.

Annotation on Shared Screen

Annotation tools are available when Share Screen is launched. When sharing a Desktop/application, select Annotate on the menu to open the tool bar.

To enable this setting in your account, go to Settings > Meeting > In Meeting (Basic) >

Allow host and participants to use annotation tools to add information to shared screens

 

Controlling Slides Shared by Another Participant

A presenter in a meeting or webinar can give slide control to other participants, so that others can control the progression of slides for the presenter. Slide control can be given to multiple participants in a meeting. Available in Microsoft PowerPoint, Office 365 PowerPoint, Google Slides, and Keynote.  

To enable the setting in your account, go to Settings > Meeting > In Meeting (Basic) > Slide Control
 

Assign Slide Control

1. Start a meeting or webinar.
2. Begin sharing a Keynote, PowerPoint, or Google Slides presentation.
3. On the sharing toolbar, click Slide Control.
   Note: This option will only be available when you are in presentation mode.
4. Select one or more participants you wish to give slide control. The slide control button will update with number of participants with slide control next to the icon.

After you’ve assigned slide control to a participant, they will retain slide control as long as you continue sharing. The slide controls will disappear if you exit presentation mode, but they will reappear when you begin presenting again. You can revoke an individual’s access by clicking their name in the list, or revoke all access by clicking the Stop Slide Control button or stopping sharing completely.

Using Slide Control

When you’ve been given access to slide control and the presenter enters presentation mode, a banner notification will appear, informing you of the new access. The slide controls will appear just below the banner, in the bottom-left corner of the presentation view.

• Click the left arrow  and right arrow  buttons to move the presentation backwards or forwards.
• Alternatively, you can use the left and right buttons on your keyboard to move the presentation backwards or forwards.

Share Multiple Screens Simultaneously

The setting to allow multiple screens to be shared simultaneously can be useful for a real-time comparison of documents or other materials by participants. This feature can either be enabled in the Zoom web portal prior to a meeting or webinar (on version 5.11.0 or higher), or enabled during a meeting by the host. 

Remote Support must be disabled for the host before the option appears as described in this article.

To enable the setting in your account, go to Settings > Meeting > In Meeting (Basic) > Screen Sharing > Under How many participants can share at the same time?, choose Multiple participants can share simultaneously (dual monitors recommended).

Or enable the setting per live meeting:

1. Start your Zoom meeting as the host.
2. To the right of the Share Screen button, click the upward arrow  and then select Multiple participants can share simultaneously.
   This allows multiple participants to share their screen at the same time.
   

Note: Participants using the Zoom mobile app can only share if no one else is sharing.

Share screens simultaneously during meeting

Any participant (including the host) using the Zoom desktop client can click Share Screen to begin sharing. Even if someone is already sharing a screen, another participant can begin sharing. 

Depending on their setup, participants will see the following:

• Participants using dual monitors can see the two most recently shared screens on each monitor.
• Participants using a single monitor see the most recently shared screen. Participants can select View Options to change the screen they are viewing.
• Participants using the Zoom mobile app see the first shared screen. They cannot change the screen they are viewing.

As the host, you can choose to switch to the option One participant can share at a time for any portion of the meeting.
