As a projector, the Vamvo VF250B combines LCD technology with 375 ANSI lumens and a resolution of HDTV 1920 x 1080. The manufacturer specifies a durability of 30000 hours for the LED light source – calculating to 20.5 years at four hours of use per day. Should a perpendicular setup to the screen not be possible, the integrated keystone correction (horizontal and vertical) helps to realign the image into a perfect rectangle. Looking at practical performance, up to 197 cm can be illuminated with 375 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 131 cm. For media input, video signals up to 1080P are supported. Furthermore, the model is Bluetooth-enabled, allowing audio signals to be sent wirelessly to external speakers. Since the projector supports Miracast and Airplay screen mirroring, video signals can also be streamed wirelessly from the end device.
