Optoma ZK551 – The True 4K UHD Laser Projector with Miracast Wireless Streaming for Professional Environments
The Optoma ZK551 is a True 4K UHD (3840 × 2160) DLP® projector featuring a DuraCore Laser light source, specifically designed for meeting rooms, conference rooms, collaborative spaces, educational facilities and professional audiovisual installations. With its 5,100 lumens brightness, 3,000,000:1 dynamic contrast ratio and True 4K UHD resolution, it delivers highly detailed images with four times more detail than Full HD, even in brightly lit environments.
The ZK551 integrates Miracast technology, enabling wireless screen sharing directly from compatible devices without requiring additional hardware. This solution simplifies collaborative presentations and meetings while improving flexibility of use in professional environments. The projector also supports HDR and HLG compatibility, as well as Amazing Colour technology, providing richer images, enhanced contrast and accurate colour reproduction.
Its DuraCore Laser light source provides a lifespan of up to 30,000 hours without lamp replacement or significant maintenance requirements. With its IP6X certification, the optical engine is protected against dust ingress to ensure long-lasting projector performance. The external power supply also improves reliability, portability and energy efficiency, while power consumption can be reduced by up to 45% compared with an Optoma lamp-based projector.
Designed for flexible installation, the Optoma ZK551 features a 1.6x manual zoom, vertical Lens Shift (+15%), horizontal and vertical keystone correction up to ±30°, as well as four-corner geometric correction. The 360° projection capability and portrait mode allow easy integration into a wide range of professional installations.
The projector is compatible with Optoma Management Suite (OMSC)™, enabling monitoring, diagnostics and centralised management of a projector fleet. Connectivity includes two HDMI 2.0 inputs, an RJ45 port, an RS232 port, a 12V Trigger, two USB-A power ports and an audio output. Its built-in 15 W speaker, 24/7 operation capability and ultra-compact design weighing only 3.2 kg make it an ideal solution for modern professional installations.
