Using Blank Screen

Overview

LanSchool Air's customizable Blank Screen feature enables you to push a Blank Screen to your students' computers. When you enable Blank Screen, students are not able to view or listen to anything on their device until the Blank Screen is disabled by the instructor. The feature can be used, for example, to:
  1. Get students' attention or return students' attention back to you
  2. Limit computer-related distractions including video and audio
