BenQ LW830ST 4,000 ANSI Lumens WXGA Laser Short Throw Projector

BenQ LW830ST – WXGA Laser Short Throw Simulation Projector

The BenQ LW830ST is a 4,000 ANSI lumen WXGA laser projector with a 0.52 short throw lens. It suits immersive rooms, simulation, museums and interactive installations where projectors need to sit close to the screen.

It is built for system integrators. A one-click blending preset, BenQ WBA white balance matching, a sealed dust-resistant engine and network management keep multi-projector installations quick to set up and reliable over the long term.

Picture Quality

The laser DLP engine produces a native 1280 x 800 image with 30-bit colour and HDR10/HLG support. Picture modes include Simulation, sRGB, Presentation and a 3D mode for compatible content.

Installation and Throw

With a fixed throw ratio of 0.521, a 100-inch 16:10 image needs roughly 1.1 m (calculated from the throw ratio). The projector supports 360° and portrait installation. 2D keystone (auto vertical, ±30° vertical and horizontal) and a 112% projection offset help align the image on site.

Connectivity and Management

Inputs include two HDMI 2.0b ports (HDCP 2.2, accepting up to 4K UHD signals), two USB-A ports, RJ45 LAN, RS232 and a 3.5 mm audio output. LAN connectivity allows remote monitoring and firmware updates over the network without touching each projector.
