The BenQ LK935 is a 5500 ANSI lumen 4K UHD laser projector built for conference rooms, hybrid meetings, collaborative spaces, and professional installations where image detail must remain visible under ambient light. Its native 3840 x 2160 resolution provides room for detailed graphics, spreadsheets, presentations, and multi window content, while 92 percent Rec. 709 coverage and dedicated presentation, infographic, video conference, and sRGB picture modes support different business workflows.
Flexible Placement for Professional Rooms
A 1.36 to 2.18 throw ratio, 1.6x optical zoom, vertical lens shift from minus 60 percent to plus 60 percent, and horizontal lens shift from minus 23 percent to plus 23 percent give installers substantial freedom when positioning the projector. Three dimensional keystone adjustment provides vertical, horizontal, and rotational correction up to 30 degrees, while 360 degree projection supports installations on walls, ceilings, floors, and angled surfaces.
Built for Long Term Installation
The laser light source is rated for 20,000 hours in Normal mode, reducing the need for lamp replacement. BenQ DustGuard construction uses a sealed laser module and enclosed light engine, with IP5X dust protection for demanding environments. HDBaseT can carry video, audio, RS232, and LAN control over one network cable for runs up to 100 meters, helping simplify permanent installations and equipment room connections.
