The Optoma LH351ST is a short-throw DLP projector designed for business presentations and meeting rooms. It uses a 4LED light source for consistent image quality in various corporate settings. The projector supports 360-degree rotation and portrait mode, allowing it to adapt to different room layouts. It can project images from a distance of 0.4 to 3.3 metres, creating display sizes between 90 and 300 inches, which suits both small huddle rooms and larger conference halls. The 16:10 native aspect ratio matches the standard output of modern computer monitors, enabling straightforward setup without complex optical adjustments.
The unit can be placed on a desk or mounted to the ceiling using compatible brackets. An integrated Ethernet port allows for wired network connectivity, and administrators can monitor or configure the projector remotely via the Optoma Management Suite (OMSC) and the Smart Control app. A single HDMI port connects to laptops and media players. The projector also features an automatic power-off function to save energy when not in use, and its internal cooling system operates at a noise level of 27 decibels.
