Overview

The BenQ LK935 is a high-resolution laser projector developed specifically for the demands of modern conference rooms and hybrid working environments. With its 4K resolution and support for the 21:9 format, it provides the ideal basis for immersive video conferences and detailed presentations. Thanks to its maintenance-free laser light source and certified dust protection, it is designed for maximum operational reliability in professional continuous use.

Benefits and special features

4K UHD resolution for precise display of the finest details and text in professional applications.
Long-life laser light source with a lifespan of up to 20,000 hours in standard operation.
Maximum installation flexibility thanks to wide lens shift (±60% vertical, ±23% horizontal).
Support for the 21:9 aspect ratio for optimised display in video conferences.
IP5X DustGuard technology effectively protects the optical unit against performance loss caused by dust.
HDBaseT port enables lossless transmission of video and control signals over long distances.
Approved for 24/7 continuous operation and flexible 360-degree installation at any tilt.
3D keystone correction and corner adjustment for fast geometry correction with angled projection.

Picture and sound quality

The LK935 uses proven DLP technology with a 0.47-inch DMD chip to achieve native 4K UHD resolution of 3,840 x 2,160 pixels. With a brightness of 5,500 ANSI lumens, the system projects high-contrast images even in rooms with ambient light, supported by a dynamic contrast ratio of 3,000,000:1. A colour depth of 1.07 billion colours ensures natural transitions and precise colour reproduction.

For audio support, a 10-watt speaker is integrated, sufficient for sound in medium-sized meeting rooms.

Mounting and installation

The projector supports a variety of installation types, including table projection, ceiling mounting, 360° installation and portrait mode. Lens shift of up to ±60% vertical and ±23% horizontal allows the image to be shifted without distortion, considerably simplifying installation in existing infrastructure.

Warranty card

For physical security, the unit has a security bolt and a Kensington lock slot. The operating temperature is between 0 and 40 °C.

Note on distance planning: add 35.1 cm plus approx. 7–12 cm for plug/cable exit.

According to the manufacturer, this projector supports image sizes from 60 inches (133 cm) to 200 inches (443 cm).

Screen size (diagonal)	Image width (approx.)	Throw distance
80 inches	177 cm	2.41 m – 3.86 m
100 inches	221 cm	3.01 m – 4.83 m
120 inches	266 cm	3.61 m – 5.79 m

The calculated throw distances are based on the manufacturer's throw ratio and are intended as guide values. As measuring points (e.g. from the centre of the lens vs. the front of the housing) often vary between data sheets, accuracy to the centimetre cannot always be guaranteed.

Running and follow-up costs

Power consumption is 405 watts in normal mode and drops to 270 watts in ECO mode. Laser technology eliminates regular lamp replacements, significantly reducing the total cost of ownership (TCO).

No regular lamp replacement required – low-maintenance in continuous operation.

Operating mode	Lifespan	2 hrs/day	8 hrs/day
Standard mode	20,000 hrs	27.5 years	7.0 years
ECO mode	30,000 hrs	41.0 years	10.5 years

The combination of 4K resolution, high brightness and flexible installation features makes it the ideal partner for demanding conference environments. Thanks to maintenance-free technology and IP5X certification, it impresses with minimal follow-up costs and maximum reliability in everyday business.
