# Sharing your screen during an Amazon Chime meeting
<a name="screen-share"></a>

You can share your screen if you use the desktop client or web app to join a meeting, or you have a supported in-room video system. If you use the desktop client, you can also stop notifications from appearing while you're sharing your screen. Remember the following:
+ If your network connection slows down, Amazon Chime prioritizes audio over video. The system pauses all video except your video tile and the screen share, and the following error message appears: **Video paused to prioritize your audio connection**. The system restores video after it resolves the network problem.
+ The Amazon Chime web app supports screen sharing on Google Chrome and Mozilla Firefox for Windows, macOS, and Linux desktops. You don't need a plugin or extension. If you installed the Amazon Chime screen share extension for Google Chrome versions 34 -71, and you now run a more recent version of Google Chrome, Amazon Chime bypasses the extension and uses the browser's native capabilities. 

**Note**  
If you want others to see your mouse pointer while you present, you must share your entire screen instead of an individual window.

The steps in the following sections explain how to share your screen and use the various screen sharing tools.

# Sharing your screen
<a name="share-your-screen"></a>

When you share a screen, you can share any open program window, or you can share your entire screen. The following steps explain how to do both.

**Note**  
If you want others to see your mouse pointer while you present, you must share your entire screen instead of an individual window.

**To share your screen during a meeting**

1. On the call control bar at the bottom of the meeting window, choose **Start screen**.

   The **Choose what to share** dialog box appears and displays thumbnail images of the applications that you're currently running.

1. Do one of the following:
   + To share an application window, choose the desired thumbnail image.
   + To share your screen, choose **Entire screen**, then choose **Entire screen** again. 

1. Choose **Share**.

Desktop users in the meeting see a **Shared screen** pop-up, and mobile users see an alert to either view or ignore the shared screen. Meeting attendees who view your shared screen can use their pointers to zoom in and out.

# Using the screen share control bar
<a name="share-controls"></a>

When a meeting host or attendee shares their screen, the screen share control bar appears: ![\[A dark gray bar with four icons.\]](http://docs.aws.amazon.com/chime/latest/ug/images/meeting-shared-screen-controls.png) 

Moving from left to right: 
+ **Hide all video** – Hides all attendee video tiles, including yours.
+ **Zoom in** – Zooms in on the shared screen.
+ **Zoom out** – Zooms out of the shared screen.
+ **Undock screen to share in a new window** – Moves the shared screen to a separate window. Other attendees continue to see the undocked window. To re-dock, close the undocked window. The shared screen appears in its original location.

# Stopping notifications while sharing

To stop notifications from appearing while you share your screen, update your Amazon Chime settings. This only applies to the desktop client.

**To stop notifications**

1. In the desktop client, open the horizontal ellipsis menu next to your name and choose **Settings**.

1. Choose **Meetings**, and under **Notifications**, choose **Suppress all notifications while screen sharing**.

# Playing videos while sharing your screen
<a name="screen-share-audio"></a>

When you play a video while sharing your screen, other meeting attendees can see the video, but they can't hear the audio. Why? By design, Amazon Chime only captures and distributes audio from microphones.

To include audio with a video, you can use the following tools to redirect the audio as a mic input to Amazon Chime.
+ OBS and a virtual camera: [https://streamlabs.com/streamlabs-obs](https://streamlabs.com/streamlabs-obs).
+ VB Cable: [https://vb-audio.com/Cable/index.htm](https://vb-audio.com/Cable/index.htm).
+ An HDMI to USB adapter cable. You route the signal out from HDMI and back in via USB.
+ Loopback: [https://rogueamoeba.com/loopback/](https://rogueamoeba.com/loopback/).

# Hiding your screenshare view
<a name="hide-screenshare-view"></a>

If you select the Amazon Chime meeting window while sharing your screen, you and others see an infinite number of meeting windows. For example:

![\[Repeated instances of the Amazon Chime meetings window, out to infinity.\]](http://docs.aws.amazon.com/chime/latest/ug/images/infinity-mirror.png)


Hiding your screenshare view prevents that from happening.

**To hide the view**

1. In the left control bar, choose the **Media layout** icon (![\[An icon showing a stylized app screen with three panels.\]](http://docs.aws.amazon.com/chime/latest/ug/images/left-control-5.png)).

1. Choose **Hide my own screenshare view**.

   A check mark appears next to the option, which remains selected until you change it.
