The W4100i is a 3D-DLP projector by Benq, whose specifications list 3200 ANSI lumens, a contrast of 3000000:1 and a UHD (4K2K) 3840 x 2160 resolution. Thanks to LED technology, the projector is rated for a lifespan of up to 20000 hours. Daily use of 4 hours makes an operational lifespan of over 13.7 years possible. Thanks to the combination of optical lens shift and digital keystone correction, the projected image's position can be adjusted very flexibly. The Distance Calculator helps find the optimal installation dimensions. 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. 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. Thanks to support for Airplay, screen content can also be cast wirelessly from a smartphone, tablet, or PC to the screen. In the specifications, the operating noise is listed at a mere 30 decibels, indicating very quiet cooling.
