Samsung WM75B Flip Pro 75" 4K Interactive Touchscreen LED Display from Samsung. The messy blackboard is replaced with this touchscreen display, which provides 4K visuals for more engaging lessons and interactive features that increases student engagement. With up to 20-person multi-touch, students can still walk up to write on the "board," or they can share their mobile screen from their seat with software like Apple's AirPlay 2. The screen can accommodate the display of up to 4 screens at once. Additional features, such as video calling and pushed content, allows the Flip Pro to move beyond the classroom and interact with the school itself and those outside its walls.
