Improved wireless display and collaboration in classrooms. ScreenBeam enables app-free screen sharing for all devices, without the need to download an app or establish a physical connection. Simply click to wirelessly connect a mobile device to the display in the room. Teacher and guest devices have different connection options, including Wi-Fi mode, Miracast™, and network infrastructures. Teachers can display up to four student screens simultaneously, and with a Windows 10 device, they can take notes in Office 365 apps and share them from the display in the room. With ScreenBeam Ghost Inking™ technology, Windows Inking latency is eliminated for a more intuitive and natural pen-on-paper experience, as well as a top-notch wireless collaboration experience.
