Delivering 3,600 lumens of brightness with a 0.496:1 throw ratio, it can produce a large 100-inch image from less than four feet away while helping reduce presenter shadows. Optoma DuraCore laser technology provides up to 30,000 hours of low-maintenance operation, while DLP imaging delivers sharp text, detailed graphics, and vibrant video. Smart Control compatibility simplifies setup and image adjustment from a mobile device. Dual HDMI 2.0 inputs, a built-in 15W speaker, flexible keystone correction, 360-degree installation, and network management capabilities make the ZH351ST ideal for demanding education and business environments.
Bright 3,600-Lumen Laser Projection
With 3,600 lumens of brightness, the ZH351ST delivers clear, readable Full HD images even in rooms with ambient lighting. Presentations, spreadsheets, educational content, and video remain vivid and easy to see, making the projector well suited for classrooms, meeting rooms, training facilities, and other professional environments.
Space-Saving Short Throw Design
The 0.496:1 short throw lens produces a large image while positioning the projector close to the screen. A 100-inch image can be created from less than four feet away, making installation easier in compact rooms while reducing distracting shadows and light shining directly into the presenter’s eyes.
Long-Life DuraCore Laser Technology
Optoma DuraCore laser technology provides dependable, lamp-free illumination with up to 30,000 hours of operating life in Eco mode. Instant power on and off, reduced maintenance requirements, lower power consumption, and no replacement lamps help reduce operating costs while supporting reliable long-term use in business and educational installations.
Crisp Full HD 1080p Detail
Native 1920 x 1080 Full HD resolution delivers detailed presentations, sharp text, clear graphics, and vibrant video content. DLP display technology helps maintain consistent image precision and accurate color performance, allowing viewers throughout the room to comfortably read presentation material and enjoy professional-quality visual content.
Smart Mobile Setup and Control
Compatibility with the Optoma Smart Control app puts essential projector functions directly on a compatible iOS or Android device. Users can control power, select input sources, adjust image settings, receive status information, and use intelligent alignment functions such as Smart Fit, helping simplify both initial installation and everyday operation.
Flexible Image Alignment Options
Horizontal and vertical keystone correction of ±15 degrees, four-corner adjustment, portrait projection, and 360-degree operation provide extensive installation flexibility. These image adjustment tools make it easier to correct geometry when the projector cannot be positioned perfectly square to the screen, supporting more creative and practical installation locations.
Centralized Professional Display Management
Optoma Management Suite compatibility allows IT teams to monitor, diagnose, configure, and control compatible displays through centralized cloud-based or local network management. Real-time monitoring can simplify maintenance across multiple rooms or facilities, making the ZH351ST especially useful for schools, organizations, businesses, and larger professional AV deployments.
Convenient Connectivity and Built-In Audio
Dual HDMI 2.0 inputs provide convenient connectivity for computers, media players, and other digital sources, while VGA, audio, USB, RJ45, RS232, and additional control connections support professional installations. A built-in 15W speaker provides clear integrated audio, helping reduce the need for separate speakers in smaller rooms.
