The Epson EB-770Fi gives a classroom a detailed display that can also be used for annotation. It suits lessons where a diagram or document is developed with the group, with the projector close to the display wall. The screen becomes part of the explanation instead of only showing finished material.
Pen contribution makes that role useful in practice. Colour projection supports illustrated lessons, and familiar high-definition video can use the same display. The close projection arrangement reduces the length of the beam path through the teaching area.
Laser illumination supports recurring use with longer rated operating intervals. Management and sharing tools help different staff use the room, while the supplied interactive accessories give the package a defined scope. It is the interactive option for a teaching space that needs both detailed viewing and work at the screen.
