Zoom: Presenting

This article details the basics of presenting and screen sharing in Zoom, including using the chat during a meeting.

This article covers the following topics:

Screen Sharing in Zoom

  1. The host and participants can share their screen by clicking Share in the meeting controls.

  3. (Optional) Enable these features on the left side of the screen share pop-out menu:
    1. Check Share Sound to share any sound played by your computer shared in the meeting (you can choose between mono and stereo sound).
    2. Check Optimize for video clip if you will be sharing a video clip in full-screen mode. Do not check this otherwise, as it could make the shared screen blurry.

  4. Click the blue Share button in the lower right corner of the window.

Sharing a Portion of the Screen

  1. Click Share Screen.

  2. Select the Advanced tab at the top of the window.

  3. Click Portion of Screen.

  4. A green box will appear, to drag over the part of the screen you would like to share. If you drag the portion you're sharing to a new location, screen sharing will pause and the green box will turn orange until you have finished dragging it to a new area.

Share Screen Menu

When you start sharing your screen, the meeting controls will move to the top of the screen. You can click and drag this to another location on the screen if you would like.

Obstructed Window While Screen-Sharing

Other participants may report seeing gray boxes obscuring the screen while you are screen sharing. These gray boxes are the windows for your Zoom controls and chat. This can be fixed by changing your screen sharing settings:

  1. Click the green New Share button in the control panel.

  2. In the window that pops up, look to the right side of the window. If the Optimize for video clip checkbox is checked, click it to deselect this option.

  3. Select the window you want to share, and click Share in the lower right hand corner.

For more information about screen sharing, please see this Zoom "Sharing Your Screen, Content, or Second Camera" documentation.

Sharing a Pre-Recorded Video

Zoom allows participants to share video with audio to participants. 

  1. Click Share in the meeting controls.

  2. Select the video from the available screens. We suggest having the video open in a separate tab, to make it easier to find.

  3. Select Optimize for video clip from the bottom of the "Share" window. This should automatically select Share sound as well. If it doesn't, select that option as well.

  4. Click Share.

Sharing a PowerPoint

By default, your PowerPoint presentation will take up your whole screen, hiding the "Chat" and "Manage Participants" controls. Follow these instructions to contain your presentation in a browser window, rather than on a full screen.

  1. Open the PowerPoint you want to present.

  2. Click Slide Show in the top menu toolbar, then click Set Up Slide Show.

    Play Slideshow and Start Slideshow from Current Slide buttons
    Your presentation will display in a window.
