Model Overview The Benq HT4550i is a 3D-DLP projector that brings 3200 ANSI lumens, a UHD (4K2K) 3840 x 2160 resolution alongside a contrast of 2000000:1. The built-in LED technology features a light source lifespan of 20000 hours. With four hours of daily operation, this corresponds to a period of 13.7 years.
To compensate for angled projection positions, the model features 2D keystone correction, which digitally corrects trapezoidal distortion.
A look at the light output reveals: The 3200 ANSI lumens are sufficient to illuminate an image width of up to 575 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 383 cm.
For media input, video signals up to 1080P and 4K as well as 3D are supported, meaning standard Blu-ray formats are processed effortlessly. Furthermore, thanks to Android TV, the projector functions as a standalone entertainment center for various video-on-demand services. As an additional feature, an integrated media player enables the direct playback of files without an external source device. Furthermore, the model is Bluetooth-enabled, allowing audio signals to be sent wirelessly to external speakers. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. Since the projector supports Airplay and Chromecast screen mirroring, video signals can also be streamed wirelessly from the end device.
Since entering the market in 2023, production has been discontinued; the manufacturer no longer actively offers the model.
