Full HD 1920 x 1080 laser projection for business and education.
The Epson EB-770F is a Full HD ultra short throw 3LCD laser projector for classrooms and meeting spaces. It delivers 4,100 lumens of colour and white brightness, while its 0.25–0.35:1 throw ratio enables projection close to the display surface.
4,100 lumens of colour and white brightness support presentations in classrooms and meeting spaces. The Full HD 1920 x 1080 image is generated by Epson 3LCD technology.
The 0.25–0.35:1 throw ratio helps match the projector to the available installation distance. Its ultra short throw design places the projector close to the projection surface.
The laser light source is rated for 20,000 hours in Normal mode and up to 30,000 hours in Extended mode. This is the approximate time until brightness decreases to 50% of initial output; actual life depends on use and environment.
