Optoma ZH451ST 4200-Lumen Full HD Short-Throw Laser DLP Projector

The Optoma ZH451ST 4200-Lumen Full HD Short-Throw Laser Projector brings high-brightness laser projection and spatial flexibility together in a compact, lightweight chassis. Operating at a native 1080p Full HD resolution, it ensures sharp, professional text and vibrant graphics for corporate boardrooms and educational environments. Additionally, it supports 4K UHD and HDR/HLG input signals, processing high-end media metadata to deliver enhanced contrast, rich textures, and superior color accuracy.

At the core of the ZH451ST is Optoma’s advanced DuraCore Laser engine, which features IP6X dust resistance to guarantee reliable, lamp-free performance for up to 30,000 hours in Eco mode. This eliminates the recurring maintenance costs and downtime associated with traditional bulb replacements while enabling instant power-on and power-off functionality.

Engineered with a dedicated short-throw lens, the projector creates a large, immersive image from close proximity to the screen. This effectively eliminates bothersome presenter shadows and glare, making it exceptionally well-suited for interactive whiteboards, smaller meeting rooms, and retail window displays. Installation is further simplified with horizontal and vertical keystone correction, four-corner adjustment, and full 360-degree and portrait orientation mounting support. Furthermore, its sustainable design utilizes an energy-efficient external power supply and a chassis built with post-consumer recycled (PCR) plastics.
