Description

The BenQ LH835ST is a 1080p (1920x1080) short-throw laser projector delivering 4000 ANSI lumens, aimed at medium and large interactive and immersive spaces. A 0.69-0.83 throw ratio produces large images from short distances, and a laser light source rated at 20,000 hours in normal mode, combined with 3,000,000:1 contrast, delivers bright, vibrant images with consistent long-term performance. Connectivity is notably modern for this class of projector: dual HDMI inputs, DisplayPort, two USB Type-A ports and a USB Type-C port with DisplayPort Alt Mode support for single-cable laptop connections, alongside RS232 for control integration and dual infrared receivers for remote flexibility. Auto screen fit, quick focus and motorised zoom simplify installation, while BenQ's white balance adjustment supports consistent colour when used in multi-projector blended setups. With 2D keystone correction and corner correction (+/-30 degrees), the LH835ST suits simulation training, interactive exhibits and immersive entertainment spaces, and is backed by BenQ's standard 3-year warranty.
