Disabling Multiple Displays
Overview
Exam administrators can restrict the use of multiple displays during an exam. If more than one display is detected, Proctorio will display the following message on the Before You Begin page: "Multiple display screens detected. Please disable all but one monitor."

Troubleshooting
To resolve the issue, physically disconnect the monitor from your device; in most cases, disabling or powering off the monitor will not satisfy the requirement.
If you are unable to disconnect the additional display(s), please try the troubleshooting steps provided below.
