Model Overview

According to Vivitek, the RU43723 model provides 5500 ANSI lumens, a contrast ratio of 20000:1 alongside a WUXGA 1920 x 1200 resolution. With its built-in laser light source, the projector achieves a manufacturer-stated lifespan of 20000 hours – equivalent to a usable life of 13.7 years at 4 hours a day.
To compensate for angled projection positions, the model features 2D keystone correction, which digitally corrects trapezoidal distortion. With its short projection distance, the short-throw model excels in smaller rooms, requiring only 100 cm of wall distance for an image width of 2 meters.
Looking at practical performance, up to 753 cm can be illuminated with 5500 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 502 cm.
Regarding signal processing, the model is compatible with incoming 1080P content as well as 3D. Thanks to MHL support, screen content from mobile devices can be transmitted via cable, including charging power for the device. Connectivity for fixed installations is rounded off by an RJ45 port for remote maintenance and an HDBaseT interface, which transmits bundled video, audio, and control data over long cable runs. Equipped with a microphone jack and built-in speakers (5W), audio signals during presentations can be played back directly without an external audio system.
Since entering the market in 2020, production has been discontinued; the manufacturer no longer actively offers the model.
