Laser Light Source
A long-life laser light source provides consistent brightness and colour performance over time, with minimal maintenance requirements compared to traditional lamp-based projectors.
High Brightness Performance
Designed for well-lit environments, the projector delivers strong brightness output to ensure clear and visible images even in spaces with significant ambient light.
Full HD Resolution
With native 4K UHD resolution, the projector produces sharp and detailed images suitable for presentations, video playback, and digital content.
IP6X - Dustproof Design
Independently tested and certified to IEC standard 60529 with an IP6X dust resistance rating. An IP6X rating means a device is completely dust-tight. It offers the highest level of protection against solid particles under the Ingress Protection standardConnectivity Options
Multiple input options support connection to a wide range of devices, ensuring compatibility with modern AV systems and simplifying integration into existing installations.
Flexible Installation, 360° Rotation Projection
Installation features such as keystone correction and digital adjustment tools allow for flexible positioning and easy image alignment in a variety of setups.
The projector offers 360° rotation, enabling flexible positioning to suit various installation needs. It can be tilted vertically at any angle, allowing projection onto ceilings, walls, floors, or portrait orientation for digital signage, ensuring optimal presentation in corporate venues of all sizes.
Edge Blending Mode
Blending Ready Mode is designed to streamline multi-projector edge blending installations by providing a consistent, pre-configured image setup straight out of the box. It helps ensure uniformity across multiple projectors, making it easier to achieve seamless large-scale visuals in professional environments.
When activated, Blending Ready Mode standardises key image parameters such as brightness response, colour balance, and gamma characteristics across all connected units. This reduces the time required for manual adjustment and helps installers achieve faster, more predictable alignment when using external edge blending tools or control systems.
By preparing each projector with consistent baseline settings, Blending Ready Mode supports smoother calibration workflows and improves overall image consistency in multi-projector configurations, particularly in simulation, projection mapping, and immersive display applications.
Optional Air-Filter
optional air filter designed to protect internal components by preventing dust, debris, and airborne particles from entering the optical engine and cooling system. Maintaining cleaner airflow, it helps preserve image quality, reduce the risk of overheating, and extend the overall lifespan of the projector, particularly in environments with higher levels of dust or contaminants.
Low Maintenance Operation
With its laser light source and durable design, the projector reduces the need for regular maintenance, lowering total cost of ownership over its operational life.
