Vivid, Clear Projection for Ambient Light Environments
Optoma LH351st with 3300 lumens of brightness, enjoy sharp 1080p visuals that stay clear and vibrant in meeting rooms, classrooms, and other well-lit spaces.

An Immersive Golf Simulation Experience
Bring the golf course to life, create an immersive environment where every round feels closer to the real thing. Enjoy lifelike fairways, detailed greens and vivid course scenery that help you feel connected to the game, whether you're practising your swing, refining your short game or playing a virtual round with friends. The large projected image makes it easier to follow the action and appreciate the layout of each hole, while the short-throw design helps minimise shadows from players as they address the ball and swing. Ideal for dedicated home simulators and indoor golf facilities, it helps transform an ordinary room into an engaging golf space for year-round practice, friendly competition and entertainment whatever the weather outside.
Effortless Setup and Reliable, Long-Lasting LED Performance
The lamp-free 4LED illumination system provides up to 30,000 hours of operation in Eco mode, eliminating routine lamp replacement and helping reduce maintenance requirements. Consistent performance and lower ongoing servicing needs make it suitable for installations where the projector is used regularly or for extended periods.

HDR Compatible
HDR, or High Dynamic Range, is a display technology that enhances the contrast and color range of video content. It allows for brighter highlights, deeper blacks, and a wider spectrum of colors, making images appear more lifelike and immersive. Unlike older formats that use a limited range of brightness and color (known as SDR or Standard Dynamic Range), HDR preserves more detail in both the darkest and brightest parts of a scene.
Flexible Installation
Short-Throw Projection
The short-throw optical system is particularly useful in smaller rooms, where conventional projectors may need to be mounted too far back. With a projection distance of approximately 0.74 to 1.26 metres, the LH351st can create a large display while keeping the projector close to the screen or impact surface.
Flexible Image Adjustment
Horizontal and vertical keystone correction of up to ±30° helps correct image geometry when the projector cannot be positioned squarely to the screen. Support for 360-degree operation adds further mounting flexibility, although the fixed lens has no optical zoom or lens shift.
Compatible with Optoma Management Suite (OMS)
Optoma Management Suite (OMS) is an intuitive display management solution, designed to streamline operations by monitoring, diagnosing and controlling audio visual displays via a local area network from a single platform and location. Users can also broadcast or schedule alerts and messages across displays and remotely program and schedule device operating hours, reducing energy consumption and lowering operating costs.

Connectivity and Control
Dual HDMI inputs and a VGA input support modern media devices alongside compatible computers and older equipment. A 3.5mm audio input, USB-A power output, VGA output, RS-232 and LAN connectivity provide additional options for audio, external devices and system control.
Integrated Audio
The built-in 10-watt speaker provides convenient sound for presentations, instructional videos and general media playback without requiring a separate audio system. A 3.5mm audio output allows external speakers to be connected when greater volume or fuller sound is required.
Quiet and Convenient Operation
Eco operation reduces both power consumption and fan noise, with noise levels rated as low as 29dB. Password protection and a Kensington lock provide additional security, while support for 24/7 operation makes the projector suitable for installations requiring extended daily use.
