BenQ LH850ST
Key Features
Brightness: The LH850ST boasts an impressive 5,000 ANSI lumens, ensuring vivid and well-lit images even in rooms with ambient light. This high brightness level is ideal for large venues and brightly lit spaces.
Resolution: It supports Full HD 1080p (1920×1080) resolution, providing sharp and detailed visuals that are suitable for presentations, videos, and detailed graphics.
Short Throw Lens: With a short throw ratio of approximately 0.5, the projector can produce a large image from a very short distance (for example, a 100-inch image from about 1 meter away). This feature is perfect for small rooms or tight spaces, reducing shadows and glare caused by presenter movement.
Laser Light Source: The LH850ST uses a laser phosphor light source, which offers advantages such as longer lifespan (up to 20,000 hours), lower maintenance, and consistent brightness over time compared to traditional lamps.
Connectivity: It includes multiple input options such as HDMI, HDBaseT, VGA, and USB, allowing easy connection with various devices, including laptops, document cameras, and media players.
Network Control & Management: The projector supports network control protocols, enabling IT managers to monitor and manage multiple units remotely using software like Crestron, PJLink, and AMX.
Built-in Speaker: It has a built-in 10W speaker, which is sufficient for small to medium-sized rooms, though external audio is recommended for larger venues.
Lens Shift and Keystone Correction: It offers vertical and horizontal lens shift as well as keystone correction, facilitating flexible installation and perfect image alignment.
Performance
Image Quality: The image quality is excellent, with vibrant colors, deep blacks, and sharp details. The high brightness ensures that visuals remain clear even in well-lit environments, making it suitable for detailed presentations and multimedia content.
Short Throw Advantage: The short-throw lens significantly enhances usability in limited spaces, allowing presenters to interact with the screen without casting shadows or obstructing the image.
Longevity and Reliability: The laser light source not only reduces maintenance costs but also provides stable brightness output over a long period, ensuring consistent performance.
