Description
Optoma ZH430UST Ultra Short Throw Laser Projector
The Optoma ZH430UST Ultra Short Throw Laser Projector delivers powerful Full HD performance with shadow-free projection in compact spaces. With 4000 lumens of brightness, it produces clear and vibrant visuals even in well-lit environments. As a result, it is ideal for classrooms, boardrooms, and collaborative spaces where visibility and interaction are essential.
In addition, this ultra short throw laser projector combines flexible installation with long-life DuraCore laser technology. Its compact design allows placement close to the wall, while maintaining strong and consistent image performance.
Ultra Short Throw Performance for Interactive Spaces
The ultra short throw lens enables a 100-inch image from less than half a metre away. Therefore, presenters can stand close to the screen without casting shadows or blocking the image.
This makes it especially effective for interactive applications, classrooms, and meeting environments where engagement matters.
Efficient Laser Technology and Eco Design
DuraCore laser technology reduces power consumption by up to 45% compared to lamp-based projectors. Consequently, it delivers up to 30,000 hours of maintenance-free operation, lowering long-term costs.
Moreover, the projector uses up to 50% post-consumer recycled materials in its chassis. Eco-friendly packaging contains up to 97% recyclable materials, while the compact size improves logistics efficiency and reduces carbon emissions.
Bright Full HD Visuals with HDR Support
Full HD 1080p resolution ensures sharp and detailed images without compression. At the same time, HDR and HLG compatibility enhance contrast and depth, creating more lifelike visuals.
Accurate colour reproduction further improves presentations, video playback, and graphics, ensuring consistent and engaging results across different types of content.
Flexible Installation and Advanced Control
Four corner correction allows precise image alignment, even in challenging installation environments. In addition, support for 360-degree projection provides greater flexibility in positioning.
Comprehensive control options, including RS232, LAN, and compatibility with Crestron, Extron, AMX, and PJ-Link, enable seamless integration into professional AV systems.
Reliable Performance and Low Maintenance
Designed for continuous use, this projector supports 24/7 operation in demanding environments. However, brief standby periods during extended use help maintain optimal performance.
Additionally, the auto power-off function reduces unnecessary energy consumption, helping to lower operating costs over time.
Practical Features for Everyday Use
A built-in speaker provides convenient audio for presentations without requiring external equipment. Meanwhile, USB power enables easy connection of streaming devices and accessories.
In summary, the Optoma ZH430UST Ultra Short Throw Laser Projector combines brightness, efficiency, and ultra short throw convenience. Not only does it deliver reliable performance, but it also supports interactive, shadow-free presentations in modern professional environments.
