High Quality Presentation
Advanced Modes for Supreme Presentation Quality
BenQ LU935’s colour modes are designed to fit all modern corporate presentation needs.
Infographic Mode: Showcasing the text and graphics in detail due to high brightness and better colour gradation through the 92% Rec.709 colour coverage, ensuring more saturated and lively colour performance.
Presentation Mode: Designed for conventional presentation with texts and charts, it creates the truest blacks and exemplary image sharpness for unmatched readability.
Video Mode: Designed for preserving dynamic colour details when playing videos in meeting room with ambient light.



Dual Colour Wheels Produce 92% Rec.709 Colour Coverage for Optimal Colour Performance
LU935’s powerful laser projection utilises a dual colour wheel system to produce unparalleled colour performance that achieves a 92% Rec.709 colour coverage. By increasing colour ratios and the purity of RGBY colour, LU935 dramatically enhances colour saturation to ensure superior presentation quality.



Laser-Enabled Ultra-High Contrast
LU935 Laser Projector creates strikingly clear images with stratospherically high-contrast ratio of 3,000,000:1 for true deep blacks, vividly rich colours, and fine subtle details. Also, it features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.



Large H/ V Lens Shift Designed to Fit Various Placement
LU935’s large and 2-way lens shift system can be used to properly align the image, shifting up to 60% vertically and 23% horizontally relative to the size of the screen; in this way, it delivers perfectly proportioned images despite installation or placement challenges in any venue.



The 1.6x Zoom for Efficient Upgrades and Installation
With 1.6x big zoom, corporations can replace outdated projectors without repositioning existing ceiling mounts, as well as place the new projector easily into any space to project large-scale images. The 1.6x zoom allows LU935 to be mounted anywhere from 3.5 to 5.6 metres from the screen and project images of 120", which is the typical image size for corporate meeting rooms, avoiding costly renovation or installation downtime



360° Rotation Projection
BenQ’s LU935 can be tilted vertically at any angle, allowing projection onto the ceiling, walls, floors, or angled signage to fulfil presentation in corporate venues of any sizes.



Advanced Image Calibration for Ideal Projection Alignment
LU935 is equipped with a two-dimensional keystone correction range of ±30° on both horizontal and vertical axes to counteract the trapezoid effect, a common phenomenon when the projector must be installed off-centre. Installers can use Corner Fit control to adjust each corner respectively, for perfectly aligned image geometry.



Display Resolution Switch for Multi Display Compatibility
Users can change the LU935 native resolution from WUXGA into 1080P through the display resolution switch function. This helps to increase the compatibility with 16:9 screens while doing multi-display projection, as well as fitting into the existing 16:9 projector screen while replacing the old one. When the native resolution is set at 1080P, the digital lens shift function will be enabled and the whole lens shift range will be up to ±72% from ±62% vertically. Thus, the installer can fine-tune and aligned the images, significantly saving more setup time.



Easy White Balance Adjustment Minimise Differences Between Projections
LU935 supports easy White Balance Adjustment in OSD, ensuring images consistency for better viewing experience, especially in multi-display conference room.



Wired Remote Control for Easy Operation
LU935’s wired remote control offers projector installers and IT managers extra set-up convenience and ease of operation. The added wired control functionality makes the device a dependable choice for projector installation adjustment. Installers and IT managers can assign a specific remote control ID to each projector, avoiding signal interference and unintentional changes when installing multiple projectors in a venue.



20,000 Hour Long-Lasting Performance
BenQ LU935 laser projectors deliver 20,000 hours of superior image quality and performance. The laser light source resists colour decay over time, making BenQ laser projectors ideal for multiple projections. This eliminates any concern for adjacent projectors generating different levels of brightness after operating periods.



Filter-Free DLP Technology for Lasting Vibrant Colour
BenQ LU935 laser projector is based on the absolute reliability of the 1-chip DLP design. The highly durable DLP chip can last over 20,000 hours without degradation, ensuring true-to-life colours and pristinely legible text over countless uses. With filter-free DLP technology, LU935 reduces total cost of ownership and no time-consuming filter maintenance to worry about.



DustGuard Pro™ Technology for Severe Conditions
LU935 is designed with BenQ DustGuard Pro™ Technology, which sealed laser modules and enclosed light engines to protect the DMD chip, colour wheel sensor, laser module, and other optical components. The design passed the dust chamber test standard for the international dustproof rating of IP5X. It effectively eliminates colour wheel sensor failure, visible spots on the image, and colour decay to significantly reduce service costs and downtime.



HDBaseT for Uncompressed Transmission and Control
LU935 works with ground-breaking HDBaseT connectivity that combines video, audio, RS-232 and LAN control signals from multiple sources including: PCs, laptops, document cameras, Blu-ray and DVDs onto a single RJ-45 cable. This ensures seamless transmissions up to 100 metres.



Third Party Network / Web Control Compatibility
LU935 is widely compatible with leading projector control systems including Extron, Crestron and PJ-Link, which fulfills network control via LAN, making it simple to integrate into corporate network infrastructures. When there is no LAN infrastructure, LU935 also supports RS-232 for reliable long-distance Installations up to 15 metres.



BenQ DMS Local
For users who would like to control all their displays remotely via LAN, the DMS Local software is ready to be downloaded for their system. DMS Local is a Device Information and Management software to use in the Windows operating system. DMS Local also supports Agent Mode, which allows users to integrate the DMS Local settings to the cloud-based DMS Cloud.
