Description
The Duo sends the same image two ways at once — 4K over HDMI straight to the panel at the front of the room, and USB to your laptop for the class joining online. You do not have to choose between the students in front of you and the ones at home, or unplug anything to switch.

Why it helps in the classroom
HDMI output means the Duo works with no computer at all — plug it into the panel and it just shows. That matters for relief teachers, for rooms where the laptop is unreliable, and for anyone who would rather not troubleshoot software with thirty students waiting. The physical buttons help for the same reason: freeze, zoom or snapshot without hunting through a menu.
Purchase orders are welcome from schools and government institutions.
