Optoma ZH450ST Short Throw Laser Projector
The Optoma ZH450ST Short Throw Laser Projector delivers high brightness Full HD performance in a compact and energy-efficient design. With 4200 lumens of brightness, it produces clear and vibrant visuals even in well-lit environments. As a result, it is ideal for boardrooms, classrooms, and professional spaces where clarity and impact are essential.
In addition, this short throw laser projector combines flexible installation with long-life DuraCore laser technology. Its compact form factor allows for easy placement, while maintaining reliable and consistent performance.
High Brightness and Short Throw Performance
The short throw lens allows large images to be projected from a short distance. Therefore, users can position the projector closer to the wall while avoiding shadows during presentations.
With 4200 lumens, the projector performs exceptionally well in bright environments. Consequently, it supports clear communication without the need to dim the room.
Efficient Laser Technology and Eco Design
DuraCore laser technology reduces power consumption by up to 45% compared to lamp-based alternatives. As a result, the projector delivers up to 30,000 hours of maintenance-free operation, lowering total cost of ownership.
Moreover, the eco-conscious design includes up to 50% post-consumer recycled materials in the chassis. Packaging uses up to 97% recyclable materials, while the compact size improves logistics efficiency and reduces carbon emissions.
Full HD Clarity with HDR Support
Full HD 1080p resolution ensures sharp and detailed visuals without compression. At the same time, HDR and HLG compatibility enhance contrast and depth, creating more lifelike images.
Accurate colour reproduction further improves presentations, videos, and graphics. Therefore, users benefit from consistent and engaging visual quality across different content types.
Flexible Installation and Advanced Control
Support for 360-degree and portrait projection allows installation in a wide range of environments. In addition, advanced control options such as RS232, LAN, and compatibility with Crestron, Extron, AMX, and PJ-Link enable seamless integration into professional AV systems.
This level of control makes the projector well suited for corporate and education deployments.
Reliable Operation and Low Maintenance
Designed for continuous use, the projector supports 24/7 operation in demanding environments. However, short standby intervals during extended use help maintain long-term performance.
Additionally, auto power-off functionality reduces unnecessary energy consumption, helping to lower operational costs.
Practical Features for Everyday Use
A built-in speaker provides convenient audio for presentations without requiring external equipment. Meanwhile, USB power allows easy connection of streaming devices and accessories.
In summary, the Optoma ZH450ST Short Throw Laser Projector combines brightness, efficiency, and flexibility in a compact form. Not only does it deliver strong performance, but it also supports low-maintenance, long-term use in modern professional environments.
