The Optoma ZH400ST is a professional short-throw laser-phosphor projector engineered for demanding applications in education, corporate boardrooms, and interactive spaces where space constraints and ambient light are primary concerns. Delivering Full HD 1080p resolution (1920x1080) with a high brightness output of 4000 ANSI lumens, it produces crisp, vibrant images that remain clearly visible even in well-lit environments. The standout feature is its ultra-short-throw lens design, which allows for a large projected image from an exceptionally close distance. With a throw ratio of 0.25:1, the projector can cast a 100-inch diagonal image from just 0.5 meters away, virtually eliminating shadows and glare while maximizing usable space in front of the screen or interactive whiteboard. This makes it an ideal solution for collaborative spaces where presenters need to stand directly in front of the display.

Utilizing a durable laser light source, the ZH400ST offers an extended operational life of up to 30,000 hours with minimal brightness degradation, significantly reducing total cost of ownership by eliminating lamp replacements and associated maintenance downtime. The sealed laser-phosphor optical engine is highly resistant to dust, ensuring consistent color performance and image stability over time in varied environmental conditions. The projector supports a comprehensive suite of connectivity options, including HDMI ports with MHL support for streaming from mobile devices, VGA, and network connectivity for control and content management via Crestron, Extron, and PJLink protocols.

Designed for flexible installation and ease of use, the ZH400ST features motorized zoom, focus, and vertical lens shift for precise image alignment without digital keystone correction, preserving image integrity. It includes advanced features like edge blending and warping for multi-projector setups and supports 3D content for immersive educational or entertainment applications. With built-in 10W speakers and audio output, it accommodates basic audio needs while offering expansion options. The combination of laser reliability, high brightness, ultra-short-throw convenience, and professional installation features makes the Optoma ZH400ST a robust and versatile visual solution for modern interactive and presentation environments.
