## Summary description

BenQ LW830ST is a short-throw laser DLP projector with WXGA (1280x800) native resolution and 4000 ANSI lumens brightness. It delivers long-life laser illumination (20,000 h normal, 30,000 h econ), fixed zoom lens with 112% offset, RS-232 control, and IP6X dust protection. Suitable for classrooms, meeting rooms and large venues requiring bright, durable projection with low noise (30 dB / 24 dB eco).

## Long description

The BenQ LW830ST is a short-throw laser DLP projector with WXGA (1280x800) native resolution and 4000 ANSI lumens brightness. Designed for installer-friendly multi-projector setups, it offers short-throw optics that produce large images from close distances, Rec.709 colour fidelity, and a long-life laser light source for extended operation.
Advantages
The LW830ST provides stable colour and consistent performance with factory white balance adjustment that reduces calibration time across multiple projectors. Its 4000 ANSI lumen laser engine delivers bright, high-contrast images while the sealed IP6X optical engine and optional replaceable filter protect internal components in dusty environments. Network firmware management and remote monitoring simplify device maintenance for IT and systems integrators.
Suitable for (tasks / use cases)
Classrooms and lecture halls requiring bright, reliable projection
Meeting rooms and corporate training centres with multi-projector installations
Exhibition spaces and museums where short-throw projection and dust protection are needed
Environments needing low-maintenance installations and remote device management
When it may not be suitable
This short-throw projector is optimised for installations where the projector can be mounted close to the screen; it may not be suitable if you require very long throw distances or ultra-high resolution beyond WXGA. It is a single-chip DLP device — users needing native 4K resolution should consider alternative models.
Key specifications
Native resolution: WXGA (1280 × 800), 16:10 aspect ratio
Brightness: 4000 ANSI lumens
Contrast: up to 3,000,000:1 (dynamic/marketing figure)
Light source: laser with rated long-life operation (20,000 hours typical)
Throw type: short-throw with approximately 0.5:1 throw ratio
Colour performance: Rec.709 coverage, up to 1.07 billion colours
Lens/offset: fixed zoom lens with ~112% offset (fixed optical configuration)
Input and control: Ethernet LAN, RS-232 control supported
Audio: built-in 15 W speaker(s)
Features: 3D support, IP6X sealed optical engine, optional dust filter, network firmware update support
Power consumption: AC 230 W (typical rating)
How to use
Mount the projector at the appropriate short-throw distance from the screen or surface according to the required image size and the projector’s throw ratio. Use the one-click blending preset when setting up multiple LW830ST units to minimise calibration effort and enable seamless edge blending. For dusty venues, install the optional filter and rely on the auto-reset timer to track filter life. Connect to the local network to enable remote monitoring, diagnostics and firmware updates over LAN.
What to consider before purchase
Required image size and installation distance to confirm short-throw suitability
Desired native resolution (WXGA) vs. higher-resolution alternatives if needed
Environment dust levels to decide whether to use the optional filter and IP6X protection
Network management needs for remote firmware updates and diagnostics
Usage recommendations
For multi-projector installations, use BenQ’s factory white balance (WBA) and the blending-ready one-click preset to reduce on-site calibration time. In dusty or high-traffic venues, combine the IP6X sealed engine with the optional replaceable filter and monitor filter usage via the built-in auto-reset timer. Connect projectors to your LAN for centralized firmware management and remote diagnostics to minimise maintenance trips.
