The BenQ LH856UST is a projector that utilizes DLP technology to produce a native resolution of 1920x1080. It has a rated brightness of 3500 ANSI lumens, making it suitable for use in rooms with some ambient light. The device supports a 16:9 native aspect ratio and provides a dynamic contrast ratio of 3,000,000:1, which defines the luminance range between the brightest and darkest areas of the displayed image. These specifications are intended to deliver detailed and legible visuals for educational or professional presentations.
A primary feature of this model is its ultra-short throw lens, which has a throw ratio of 0.33. This design allows the projector to be placed very close to the projection surface, reducing the potential for shadows and glare. The light source is a laser with a service life of 20,000 hours in standard mode, which can extend to 38,000 hours in economic mode. This long operational lifespan minimizes the need for routine maintenance and lamp replacements compared to traditional bulb-based projectors.
For connectivity, the projector is equipped with two HDMI 2.0 ports, two VGA ports, and two USB ports, accommodating a variety of source devices. An integrated Ethernet LAN port enables network control and management. Audio output is handled by two built-in speakers with a combined RMS rated power of 10 watts. The unit also includes features such as vertical and horizontal keystone correction for image alignment and supports ceiling mounting for flexible installation.
