To share your screen, during a meeting session:

  1. Click Share screen
  2. When you screen share, you use browser specific interfaces.

    On the Share your screen permission window, select one of the following:

    • Your Entire Screen (in Chrome, Firefox, Safari (13+), or Edge)
    • Application Window (in Chrome)
    • Chrome Tab (in Chrome)
  3. Select the appropriate screen to share.
  4. Click Share
  5. CafeX notifies you at the bottom of the screen that you are sharing.
    • To hide the notification, click Hide.

Important: If you are using MacOS Catalina or later, you have to give permission to your browser to record your screen. See: Control access to screen recording on Mac.


  • Only one person can share their screen at a time.
  • Chrome and Firefox need permission to access you camera to be able to share you screen.
  • You can only share your screen if you are using Firefox, Chrome, Safari (13+) or Edge. You can only share your application when you are using Chrome. Participants who are using any other browser cannot share their screen, but they can view a screen shared by another participant.
  • Safari (13+) only shares the desktop on which the Safari window is open; you may need to move an application that you want to share to the Safari screen.
  • If your screen share includes your CafeX meeting, a receding set of nested screen images is displayed; this can be confusing for your meeting participants—consider minimizing your browser, or moving to another tab, if appropriate.
  • It may not be possible to share applications that use Chrome or Chromium libraries, other than Chrome itself.

To stop sharing, either:

  • Click Screen share

  • If the notification bar is at the bottom of screen, click Stop Sharing

Viewing a shared screen, including zoom and pan:

  • By default, CafeX displays the shared screen in your CafeX browser window.
  • To enlarge the CafeX meeting display, including the shared screen, click Fullscreen.
  • To zoom in so that you can see an area of the shared screen in greater detail, double-click on the shared screen, then drag the pan tool to move around the zoomed in image, then use the mouse or trackpad to zoom in or out further:
