Short throw projector Optoma ZH450ST 4200 ANSI lumens DLP 1080p 3D
The Optoma ZH450ST is a compact short-throw DLP projector with Full HD 1080p resolution and 4200 ANSI lumens brightness. Designed for continuous, low-maintenance use, it employs DuraCore laser technology for up to 30,000 hours of operation without lamp replacement. The unit features a fixed short-throw lens (7.51 mm), a built-in speaker, RS232 control, and an external power supply in a compact white chassis that uses post-consumer recycled plastics.
The ZH450ST provides bright 1080p images from a short distance, enabling installation less than half a metre from the screen or wall. Laser illumination reduces power consumption compared with lamp-based models, offers a long service life up to 30,000 hours, requires minimal maintenance and is mercury-free. The projector is compact—up to 34% smaller than previous Optoma models—uses an external power supply for reliability and energy efficiency, and its packaging and chassis incorporate high levels of recyclable and PCR materials.
Position the ZH450ST less than half a metre from the projection surface for a short-throw image. Connect video sources to the projector's input ports and use RS232 for remote monitoring or control where available. Power the unit via the supplied external power supply and adjust focus/keystone as needed for a sharp 1080p image. For best results, place the projector on a stable surface or mount it according to installation guidelines and ensure adequate ventilation around the chassis.
For reliable long-term operation, keep vents clear and operate the projector in a clean, dust-minimized environment. Use the RS232 interface or network control (if provided by the installation) for centralized monitoring in corporate installations. Select screen sizes and placement consistent with the projector's short throw specifications to avoid image distortion and ensure optimal focus across the image area.
