Description

Description

The Optoma ZK551 is an extremely compact and advanced Laser True 4K UHD projector, specially optimized for conference rooms, educational institutions, and demanding professional environments. Thanks to the built-in Miracast technology, it enables instant, wireless screen sharing without the need for additional equipment, simplifying collaboration during everyday presentations. With impressive brightness of 5100 ISO Lumens, IP6X dustproof certification, and eco-friendly DuraCore Laser technology, it delivers vivid images with 8.3 million pixels and a lifespan of up to 30,000 hours without maintenance. Its redesigned, highly compact chassis reduces power consumption by up to 45%, while support for the Optoma Management Suite (OMS)™ allows full remote management and monitoring of your equipment.

Built-in Miracast Technology for Wireless Projection

The Optoma ZK551 projector redefines collaboration in conference rooms and classrooms thanks to its built-in Miracast technology. It enables instant, wireless screen sharing (wireless display sharing) and mirroring from iOS, macOS, Android, and Windows devices without the need for additional accessories or complex hardware setups. This feature simplifies presentation workflows, eliminates cable clutter, and provides a seamless BYOD (Bring Your Own Device) experience for every user.

True 4K UHD Resolution & Brightness 5100 ISO Lumens

Enjoy unparalleled image quality with the CTA-approved True 4K UHD resolution, which displays 8.3 million pixels on the screen—four times the detail compared to Full HD. Combined with the top brightness of 5100 ISO Lumens and a contrast ratio of 3,000,000:1, the ZK551 delivers crystal-clear, bright images with vivid sRGB colors even in environments with strong artificial or natural lighting, allowing you to project content from 20" to 300" inches.

Eco-Friendly DuraCore Laser Technology & Reduced Cost

Designed with sustainability in mind, the ZK551 incorporates DuraCore Laser lighting technology, offering up to 30,000 hours of lifespan without the need for lamp replacement. The device reduces power consumption by up to 45% compared to traditional lamp projectors, while its chassis is made from 50% recycled PCR plastics. The IP6X dustproof certification protects the optical engine from dust, ensuring uninterrupted operation 24/7 and minimal maintenance requirements.

Compact Design, 1.6x Optical Zoom & 360° Flexibility

With a size up to 34% smaller than previous Optoma models, the ZK551 offers unmatched installation flexibility in any space. It features a large 1.6x optical zoom, vertical lens shift (+15%), and Four Corner Correction for perfect alignment on irregular walls. Additionally, it supports 360° projection and Portrait Mode, making it ideal for specialized installations, digital signage, and demanding corporate environments.

Remote Management via Optoma Management Suite (OMS)™

Gain complete control of your projection systems with the cloud-based platform Optoma Management Suite (OMS)™. IT administrators can monitor operation in real-time, perform diagnostic checks and schedule device functions remotely, reducing downtime. Additionally, the system allows for sending notifications and emergency alerts to all connected screens within the business.

Full Corporate Connectivity & Built-in 15W Speaker

The projector offers extensive control and connectivity options, such as dual HDMI 2.0 ports, RS232, RJ45, 12V Trigger and compatibility with Crestron RoomView, AMX, and Extron automation systems. The USB-A port (5V/1.5A) allows for immediate power supply to external devices, while the built-in powerful 15W speaker provides clear and loud sound without the need for external audio equipment.

Throw Ratio
2.24 :1

Throw Ratio

The throw ratio or projection distance ratio indicates the width of the image produced by the projector when placed at a specific distance from the screen.

2. For example, a throw ratio of 1.3:1 means that the image will have a width of 1 meter when the projector is placed at a distance of 1.3 meters from the screen.
Contrast
3000000 :1

Contrast

Contrast refers to the difference between the brightest and darkest points of an image. It is measured as a ratio, e.g., 3000:1, where a higher ratio means deeper blacks and more vibrant colors, thus improving image quality.
