Media Reviews

Epson CB-680 can project a large 80-inch screen at a projection distance of approximately 52cm*2. The ultra-short-throw projection effectively avoids shadows on the projection surface and reduces direct projection light to the human eye, making lessons in front of the screen more comfortable.

With a brightness of 3,500 lumens*1 for white and color and a contrast ratio of 14,000:1*1, the Epson CB-680 delivers clear, bright, natural color images in bright classroom environments.
