The A357D is a LCD projector by KOGATA, whose specifications list 550 ANSI lumens, a contrast of 20000:1 and a HDTV 1920 x 1080 resolution. KOGATA lists a runtime of 30000 hours for the LED in this projector, which translates to 20.5 years with 4 hours of daily use. To ensure a rectangular image even with asymmetrical placement, the projector includes digital keystone correction for both the horizontal and vertical axes. Regarding projection size, the value of 550 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. Regarding signal processing, the model is compatible with incoming 1080P content and 4K. 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. In the specifications, the operating noise is listed at a mere 28 decibels, indicating very quiet cooling.
