## Long description

BenQ LK835ST is a short-throw DLP laser projector with native 4K (4096×2400) resolution and 4000 ANSI lumens brightness. Designed for quick installation, the LK835ST combines motorised zoom and focus with 3D keystone correction and curve-screen warping to deliver detailed, colour-accurate images for classrooms, meeting rooms and small auditoriums.
Advantages
The laser light source offers long maintenance-free operation with a rated lifespan of up to 20,000 hours (and up to 30,000 hours in Eco Mode) so there is no lamp replacement required. Motorised zoom and focus, Auto Screen Fit and Auto 2D Keystone with Corner Fit simplify alignment and enable precise image positioning. With a short throw ratio of 0.69–0.83 and strong 4000 ANSI lumen output, the projector reproduces bright, high-resolution 4K content even in moderate ambient light. Built-in Wi‑Fi, RS‑232 and HDMI connectivity allow flexible installation and control.

How to use
Place the projector at the appropriate short-throw distance from the screen according to the required screen size (60–120" / 1,524–3,048 mm). Use the motorised zoom and focus to adjust image size and sharpness. Run Auto Screen Fit to automatically align the image in three guided steps, and apply Auto 2D Keystone and Corner Fit if needed for fine adjustment. Connect sources via HDMI or use Wi‑Fi for wireless content; RS‑232 can be used for centralized control. For curved screens, enable warping to match the projection surface.
Usage recommendations
For best results, ensure a minimum 2-inch (≈50 mm) unobstructed border around the screen, choose standard aspect ratios (16:9, 16:10, 4:3, 1:1) for full Auto Screen Fit support, and use Eco Mode to extend laser life and reduce maintenance.
