The projector D4520 by Vivitek operates as a 3D-BrilliantColor-DLP device with 4600 ANSI lumens, a XGA 1024 x 768 resolution and a contrast of 2200:1. According to Vivitek, the included lamp lasts up to 1500 hours. Both optical image shifting (lens shift) and digital keystone adjustment are included, enabling exact alignment on the screen. Thanks to the interchangeable lens system, the device can be equipped with optional lenses to react flexibly to different room sizes. Exact values for specific rooms are provided by the Projector Calculator. Looking at practical performance, up to 591 cm can be illuminated with 4600 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 394 cm. Regarding signal processing, the model is compatible with incoming 1080P content. This model dates back to 2013 and is no longer part of Vivitek's current product range.
