Ditto provides an easy to use application for sharing/mirroring your screen to the room display. It is compatible directly from the Chrome web browser without installing anything. There are also applications for Windows, Mac, iPad, and Android devices. SSRI IT pre-installs the app on all PRI laptops.
Ditto can also be used with Zoom or Teams meetings. Join the meeting on your device. Then share the meeting screen to the room display using Ditto. The meeting will use the microphone and camera on your device.
The basic idea is that you open the app on your device or visit https://connect.goditto.com/. Enter the room code shown on the room display. Then choose what to share.
