Vivitek delivers non-stop performance for galleries and museum applications with the compact DU4381Z-STWUXGA laser projector.


4 July 2023, Hoofddorp, The Netherlands - Vivitek - the visual display brand for all meeting spaces – has delivered a Short Throw laser projector packed with non-stop performance, value and durability with the introduction of the new DU4381Z-ST WUXGA. Ideally suited to the needs of galleries, museums, the education sector and and commercial applications, the DU4381Z-ST offers 6,100 lumens of high brightness – an increase over its predecessor, the DU4371-ST - a 3,000,000:1 contrast ratio, and up to 30,000 hours of laser light source life.


Large screen projection in tight spaces


Thanks to its advanced design, the DU4381Z-ST brings the benefit of large projection sizes to any venue, even with limited installation space. With its 0.5 short-throw lens, this projector only needs a distance of two metres from the wall to achieve an impressive image size of 185 inches. At a distance of 3.23 metres, it can still deliver a razor-sharp projection with a diagonal image of 300 inches.


Additionally, the DU4381Z-ST's lightweight design of 10.5 kg and 360-degree positioning options enable limitless positioning possibilities, granting venues like museums and galleries unparalleled freedom in projector placement. It eliminates previous limitations that hindered creative installation and immersive visual experiences.


The DU4381Z-ST is equipped with DLP® DarkChip3 and BrilliantColor™ technologies to ensure a brilliant bright and colour-uniform picture with a brightness of up to 6,100 lumens thanks to the advanced laser phosphor light source. Additionally, it has a 3D synchronization port for compatibility with the active 3D synchronization protocol for IR (infrared). To facilitate installations where the image signal needs to be transmitted over long distance by cable, the HDBaseT ™ interface and a standard CAT5e / 6-LAN interface have been integrated in the DU4381Z-ST.


Uninterrupted performance


With this projector being powered by a laser light source, it is perfectly suited for 24/7 operation. The advanced projector’s fan error auto protection will bring users peace of mind that the image will never fail. Even in the rare event of a fan failure during operation, the projector will still function stably without the need for immediate shut down. This ensures uninterrupted gallery presentations, museum immersive infotainment and even lessons and presentations to continue without interruptions.


Easy Monitoring and management


For network monitoring and management the short throw projector supports Crestron® RoomView ™ software. The Vivitek PJ-Control tool can also be utilized with the DU4381Z-ST to control viewing options, settings, scheduling, and display adjustment features. For added convenience, it also helps users to control multiple projectors remotely over the network, allowing for the creation of projector groups for simultaneous control.

Commenting on its introduction, Holger Graeff, General Manager, Vivitek EMEA, said: “Performance, brightness, value and durability are the hallmarks of Vivitek projectors, and the new DU4381Z-ST majors in all of them. With this new model, we’re offering new levels of performance and value to deliver a projector that’s class-leading and meets the needs of its target market.”
