Model Overview The projector EB-780Ei by Epson utilizes LCD technology and, according to the spec sheet, achieves 4200 ANSI lumens, a contrast of 5000000:1 at a resolution of HDTV 1920 x 1080. This is a laser projector with a light source designed to last for 30000 hours – equivalent to a usable life of 20.5 years at 4 hours a day.
To ensure a rectangular image even with asymmetrical placement, the projector includes digital keystone correction for both the horizontal and vertical axes. With its built-in wide-angle optics, the device belongs to the category of short-throw projectors. An image width of 2 meters is realized from a short distance of 50 cm.
A look at the light output reveals: The 4200 ANSI lumens are sufficient to illuminate an image width of up to 564 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 376 cm.
In terms of video signals, the device processes resolutions up to Full HD 1080P and 4K. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. Since the projector supports Miracast and Airplay screen mirroring, video signals can also be streamed wirelessly from the end device.
Regarding noise emissions, the model proves to be exceptionally quiet during operation, producing just 30 decibels.
