With the W350, topeby offers a LCD projector that features 580 ANSI lumens, a contrast of 1000:1 and a resolution of HDTV 1920 x 1080. The LED unit of this model is rated for up to 30000 hours of runtime – calculating to 20.5 years at four hours of use per day. For basic image adjustment, the device is equipped with horizontal and vertical keystone correction, allowing digital compensation for trapezoidal distortion at angled projection setups. A look at the light output reveals: The 580 ANSI lumens are sufficient to illuminate an image width of up to 245 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 163 cm. For media input, video signals up to 1080P and 4K 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.
