WXGA 3,500 Lumen, Short-throw Projector

The Optoma LW351ST is a compact WXGA short-throw projector designed for business, education and immersive entertainment, including home golf simulation. Using advanced 4LED technology and delivering 3,500 lumens of brightness, it produces vivid, clear images with natural colours in classrooms, meeting rooms and other spaces with ambient light. Its 1280 × 800 resolution and 16:10 aspect ratio provide a practical widescreen format for presentations, educational content and video, while support for screen sizes up to 300 inches creates an engaging large-screen experience. The exceptionally short 0.49:1 throw ratio allows a large image to be projected from close to the screen, making it particularly useful in smaller rooms and golf simulator setups.

Designed for dependable, low-maintenance operation, the LW351ST offers up to 30,000 hours of LED light-source life in Eco mode and supports continuous 24/7 operation. Its fixed short-throw lens helps simplify installation, while horizontal and vertical keystone correction of up to ±30° allows image alignment when the projector cannot be positioned perfectly square to the screen. Connectivity includes two HDMI 1.4a inputs, VGA, audio input and output, USB-A power, RS-232 and RJ45 network control. A built-in 10W speaker provides convenient onboard audio, and compatibility with Optoma Management Suite Cloud enables remote monitoring and management for installations across multiple rooms or sites.

Highlights
  • WXGA resolution of 1280 × 800 with a 16:10 aspect ratio provides a spacious image suited to presentations, educational content, digital signage and golf simulation.
  • 3,500 lumens of brightness helps maintain clear, vibrant images in rooms with ambient lighting, making it practical for classrooms, meeting rooms and multipurpose spaces.
  • The fixed 0.49:1 short-throw lens projects a large image from close to the screen, helping reduce shadows and keeping the projector out of the way in smaller rooms and golf simulator setups.
  • The lamp-free 4LED light source offers up to 30,000 hours of operation in Eco mode, reducing replacement requirements and ongoing maintenance.
  • A rated contrast ratio of 300,000:1 helps create visible separation between bright and dark areas, supporting clearer detail in presentations, videos and simulated environments.
  • Horizontal and vertical keystone correction of ±30° helps correct image distortion when the projector is installed off-centre or at an angle.
  • Support for 360-degree installation and portrait projection allows flexible mounting orientations for specialist displays, signage and creative installations.
  • Compatibility with multiple 3D formats enables stereoscopic content playback from supported sources, expanding its use beyond standard two-dimensional projection.
  • Two HDMI inputs, VGA, audio input and output, and a powered USB-A port support a mix of modern and legacy equipment, external audio and powered accessories.
  • RJ-45 network connectivity and RS-232 control support integration with room-control systems, while Optoma Management Suite Cloud enables centralised monitoring. Password protection, a Kensington lock slot and 24/7 operation support managed commercial installations.

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 LW351st 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.
