This projector is named EF-11, originates from Epson, and its data sheet shows 1000 ANSI lumens, a contrast of 2500000:1 and a resolution of HDTV 1920 x 1080. The image geometry can be adjusted via the built-in keystone correction so that a clean, rectangular display is achieved even with non-ideal placement. Regarding projection size, the value of 1000 ANSI lumens allows for an image width of up to 321 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 214 cm. For media input, video signals up to 1080P are supported. As an additional feature, an integrated media player enables the direct playback of files without an external source device. Since the projector supports Miracast screen mirroring, video signals can also be streamed wirelessly from the end device. A look at the data sheet confirms a very subtle fan noise for the projector at just 27 decibels.
