Eco-friendly compact high brightness Full HD short throw laser projector
The ZH521ST is one of Optoma's most compact and hassle-free Full HD 1080p DuraCore laser projectors to date. Designed for maintenance-free continuous operation, this 5300 ISO lumen projector delivers powerful image performance with flexible installation features and extensive connectivity options in a sleek, compact form factor, up to 34% smaller than previous Optoma models.¹
To support Optoma’s commitment to sustainability, the ZH521ST cuts power consumption by up to 45% compared to Optoma’s lamp-based projectors.² Energy-saving DuraCore laser technology ensures a long product lifespan of up to 30,000 hours without the need for additional lamps, requires minimal maintenance, and is mercury-free, further lowering its carbon footprint.
With Optoma Management Suite (OMSC)™ you can also remotely manage this projector and other compatible devices with ease. This powerful cloud-based solution offers effortless control, real-time monitoring, and scheduling, helping to reduce downtime, streamline operations, and cut operating costs.
This latest model is also compatible with Optoma's new Smart Control App* for Android and iOS, several features can be managed without the need for a PC. Power on and off, adjust the volume, modify and set display modes and make image adjustments remotely via your smart phone.
Enhanced for golf simulation, this projector features a purpose-built throw ratio and curated golf sim picture modes. For a more immersive and true-to-life playing experience, Optoma has worked closely with colour experts at GSPro to develop a dedicated GSPro mode.4
Geared for conference rooms, boardrooms, and other corporate spaces, the ZH521ST has a short throw lens meaning it can be positioned less than half a metre from any wall. For ultimate convenience it comes with RJ45 and RS232 connection for monitoring and controlling and a built-in speaker.
