How do I use Zoom to monitor all meeting participants' desktops?

Quick Links: | Prerequisites | Instructions | Troubleshooting |

Zoom allows hosts to view all participant screens simultaneously. This guide explains how to utilize the "All screens mode" in Zoom for viewing all meeting participants' screens simultaneously, ensuring that hosts can monitor participant activity effectively. This mode provides a comprehensive view of both the participant's video and desktop, essential for some workflows.

This is not an officially-supported proctoring solution. While Zoom's "All screens mode" could be used to achieve proctoring goals, instructors MUST comply with the Policy for the Use of Digital Technologies in Teaching and Learning.

Students need to be notified that this monitoring will be used during selected assessments as early as possible. Notification should be in:

  • the course syllabus
  • the course description
  • and throughout the Canvas course by the student load date or student access date.


  • A Zoom account.
  • Familiarity with Zoom's meeting control tools.
  • A computer with dual monitors is recommended (but not required) for an optimal experience.

Step-by-Step Instructions

To use Zoom's "All screens mode," do the following:

Before the meeting

  1. Navigate to your Zoom settings page
  2. Under Meeting > In Meeting (Basic), ensure that Screen Sharing is enabled.
  3. For the option “How many participants can share at the same time?”, select Multiple participants can share simultaneously. Using dual monitors is recommended for this setting.
  4. Check the All screens mode checkbox to enable this feature for the meeting.

During the meeting

  1. Start a Zoom meeting as the host.
  2. In the meeting control toolbar, select the small up arrow next to Share Screen [1].
  3. From the additional screen sharing options, choose Start All Screens Mode [2].
    Enable all screens mode
  4. A prompt will appear. (Optional) Select Allow participants to view shares [1] if you want students to be able to see everyone else's screen. Depending on your use case, we suggest leaving this option off.
  5. Review the details, then select Start [2] to continue.

  6. Participants will receive a prompt to share their desktop. They can choose to Start Sharing or select Not Now to decline.

  7. As participants share their screens, their videos and shared desktops will appear side-by-side [1] . Participants who do not share will be displayed at the top of the window [2].
  8. If participants are not allowed to view screens, they will only see other participants' video tiles in gallery or speaker view.
  9. As more participants share their screens, additional pages will be created. Use the left and right arrows to navigate between these pages [3].
  10. To exit "All Screens Mode," select the All Screens indicator [4] in the top-left corner of the meeting window, then click Stop All Screens Mode.

  11. Participants can stop sharing their screen at any time from their device. The host can also stop this from the advanced sharing options where this mode was initiated.


  • If you cannot enable "All screens mode," check your account's settings or contact the Technology & Learning Program for assistance.
  • Ensure participants have a stable internet connection to prevent disruptions during screen sharing.
  • If participants have trouble sharing their screens, verify they have selected Start Sharing when prompted.
