As a presenter, desktop sharing allows you to share your screen with other participants in the Conferences interface. Moderators are most often the presenter, but presenters can also be participants who are invited to be a presenter, such as a participant invited to be a guest speaker. Moderators can allow any participant to be a presenter at any time.

Desktop sharing is supported on all major browsers with either Java or WebRTC (web real-time communication).

Java

By default, the desktop sharing process runs as a Java application, which runs outside your browser by launching a Java Network Launch Protocol (JNLP) file called screenshare.jnlp.

  • The Java application must be downloaded and run each time you want to share your desktop. As part of the download process, the Conferences interface displays a set of images that guide you through the download specific to your operating system (Mac or PC) and browser (Firefox, Chrome, Internet Explorer, Edge, or Safari).
  • You can pause screen sharing at any time.
  • Users presenting on a PC can choose the screen sharing area in their desktop. Users presenting on a Mac share the entire desktop window by default.
  • If you have trouble installing the Java file, you may need to update Java to the most recent version.

 

WebRTC

Chrome and Firefox browsers support WebRTC sharing, which provides a built-in browser screen sharing experience.

  • WebRTC requires installing a browser extension before sharing your screen as a presenter and is supported for Chrome and Firefox. The extension only has to be installed one time per browser.
  • WebRTC does not support pausing screen sharing, but screen sharing can easily be enabled again at any time.
  • Regardless of your computer operating system, WebRTC allows you to share your entire screen or a specific application window.
