BenQ has announced two new short-throw laser projectors designed for specialized applications. The LK830ST and LH830ST target different markets, with the former focusing on simulation environments and the latter on decorative projection applications.
Designer: BenQ
Both projectors use laser light sources and offer 4,000 ANSI lumens brightness. The key difference lies in their resolution capabilities and intended use cases.
LK830ST Specifications and Advanced Features
The LK830ST delivers native 4K UHD resolution at 3840 x 2160 pixels. BenQ markets this model as a “Laser Simulation Projector” for applications including golf simulators, interactive classrooms, and museum installations.
The projector covers 93% of the Rec. 709 color space and offers a 3,000,000:1 contrast ratio. It supports refresh rates up to 120Hz, which makes it suitable for gaming and interactive applications where smooth motion matters.
Input lag measures 16.7ms at 1080p@60Hz. The horizontal frequency range spans 15 to 135 KHz, while vertical scan rates range from 23 to 240 Hz. The projector supports multiple viewing modes including Simulation, 3D, HDR10, HLG, and sRGB for different content types.
BenQ has designed the LK830ST with several professional installation features. The projector supports 360-degree installation flexibility, allowing it to be mounted in any orientation including portrait mode. This versatility opens up creative installation possibilities for unique spaces and applications.
Blending Ready Mode and Professional Integration
One standout feature is the “Blending Ready Mode,” which provides a one-click preset for multi-projector installations. This feature minimizes setup effort when creating large-scale projection displays using multiple units. The factory-calibrated white balance values further streamline the edge blending process, ensuring consistent color reproduction across multiple projectors.
The projector also includes BenQ’s White Balance Adjustment (WBA) system, which helps maintain color consistency over time and across multiple units. This becomes particularly important in commercial installations where precise color reproduction matters.
Corner Fit functionality allows fine-tuning of image geometry on each corner, making it possible to project onto uneven surfaces or achieve perfect alignment in challenging installation scenarios. Combined with 2D keystone correction of ±30 degrees on both horizontal and vertical axes, installers have comprehensive tools for image alignment.
LH830ST House Mapping Capabilities
The LH830ST offers Full HD resolution at 1920 x 1080 pixels. BenQ positions this as a “House Mapping Projector” for decorative applications, including projecting seasonal displays onto building exteriors or creating themed environments in commercial spaces.
Like its 4K counterpart, the LH830ST delivers 4,000 ANSI lumens and covers 93% of the Rec. 709 color space. It shares the same 120Hz refresh rate capability and laser light source longevity ratings.
The LH830ST includes specialized features for house mapping applications. A 116% projection offset reduces the need for tilting and keystone adjustments when projecting onto building facades. This design consideration helps maintain optimal image quality without compromising brightness or resolution through excessive keystone correction.
The projector uses a dual color wheel system specifically optimized for the wide color gamut requirements of decorative projection. This ensures vivid colors when projecting holiday displays, advertisements, or themed content onto exterior surfaces.
Durability and Environmental Protection
Both models feature IP6X dust certification, providing complete protection against dust ingress. Optional dust filter housings are available for particularly harsh environments. This level of protection makes them suitable for outdoor installations, industrial environments, or locations where dust exposure is a concern.
The laser light source is rated for 30,000 hours in Eco mode or 20,000 hours in Normal mode. Users can project images up to 300 inches wide using the 0.5:1 throw ratio, making them suitable for large-scale applications in relatively compact spaces.
Both projectors measure 279 x 121 x 229mm and weigh 3.4kg. The compact footprint allows flexible installation in spaces where traditional long-throw projectors wouldn’t fit.
Connectivity and Smart Features
Connectivity includes HDMI ports, LAN connections, USB inputs, and RS-232 interfaces for professional system integration. Each model includes a built-in 15W speaker and Wi-Fi connectivity with over-the-air firmware update capability.
The OTA update system ensures projectors stay current with new features and improvements without requiring physical access to the units. This becomes particularly valuable for installations in difficult-to-reach locations or when managing multiple projectors across different sites.
Both models support vertical scan rates from 23 to 240 Hz and horizontal frequencies from 15 to 135 KHz, providing compatibility with a wide range of input sources and content types.
Market Positioning and Applications
BenQ appears to be targeting niche markets rather than general consumer applications. The LK830ST aims at users requiring 4K resolution for detailed work, including golf simulation systems, museum exhibits, interactive educational displays, and theme park attractions.
The LH830ST provides a lower-cost option for decorative and entertainment applications where Full HD resolution suffices. Potential applications include architectural projection mapping, seasonal building decoration, retail displays, and event production.
Pricing and Market Availability
BenQ will officially release both models in September 2025. European pricing is set at €2,399 for the LK830ST and €1,899 for the LH830ST, both including VAT.
Some European retailers have already begun taking pre-orders. Golfroom currently lists the LK830ST at €1,999, while other retailers offer the LH830ST starting around €1,584.
US pricing and release dates have not been announced. Both models appear on BenQ’s American website, but without specific availability information.
These projectors join BenQ’s existing short-throw lineup, which includes the LH835ST and LK835ST models with different throw ratios and lens systems. The new models differentiate themselves through specialized features for simulation and house mapping applications, plus enhanced installation flexibility through 360-degree mounting capabilities and advanced blending tools.
The company’s focus on professional features like factory calibration, blending ready modes, and comprehensive geometric correction tools suggests these projectors target commercial installations rather than consumer home theater applications.
