Full HD laser projection designed for demanding professional environments
The Optoma ZH521ST projector has been designed to deliver impeccable image quality in all professional and educational settings. A short-throw model, it combines high brightness of 5,300 lumens with a Full HD 1080p resolution and a dynamic contrast ratio of 3,000,000:1. Its 0.79:1 short throw allows you to obtain a large image with limited projection distance, while its compact format, up to 34% smaller than previous comparable Optoma generations, makes integration easier. Its DuraCore laser light source, certified IP6X, offers up to 30,000 hours of use with minimal maintenance. Capable of operating 24/7 and projecting at 360°, the ZH521ST is a flexible, durable and high-performance solution for demanding environments.

Ideal brightness for large spaces
Designed for meeting rooms, professional spaces and golf simulation setups, the Optoma ZH521ST combines high brightness of 5,300 lumens with a Full HD 1080p resolution and a dynamic contrast ratio of 3,000,000:1. Its 0.79:1 short throw allows you to obtain a large image with limited projection distance, while its compact format, up to 34% smaller than previous comparable Optoma generations, makes integration easier. Its DuraCore laser light source, certified IP6X, offers up to 30,000 hours of use with minimal maintenance. Capable of operating 24/7 and projecting at 360°, the ZH521ST is a flexible, durable and high-performance solution for demanding environments.
DuraCore laser technology: performance and peace of mind
The ZH521 relies on a particularly reliable and economical DuraCore laser light source. Capable of reaching up to 30,000 hours of use without lamp replacement, this technology greatly reduces maintenance operations and associated costs. Certified IP6X for better dust resistance, this projector is designed for continuous operation in intensive environments. In addition, its optimized energy consumption and mercury-free design contribute to a more environmentally friendly approach.


Flexible installation and simplified management
Designed to integrate easily into all types of spaces, the Optoma ZH521ST features horizontal and vertical keystone correction of ±30° as well as 360° projection compatibility and portrait mode. These features allow for quick and flexible installation, even in complex configurations. The projector also includes advanced network control functions via RJ45 and Optoma Management Suite (OMS), making it easier to monitor and maintain multiple devices remotely in professional environments.
Its Golf Sim mode optimizes greens, blues and details, while the GSPro dedicated mode, developed with GSPro color specialists, enhances the realism of simulations. Four-corner geometric correction and keystone adjustment on the horizontal and vertical axes simplify image alignment when the projector is off-center or installed facing an uneven surface. A 15 W speaker, two HDMI 2.0 inputs, powered USB-A ports and full control connectivity finally make it possible to create an efficient audiovisual setup without multiplying equipment.
