BenQ LH830ST Short Throw DLP Full HD 4000 ANSI lm Laser Projector, Black

The BENQ LH830ST is a short-throw projector that utilizes a DLP system and a laser light source to deliver a consistent image. It operates at a native resolution of 1920x1080 and has a brightness output of 4000 ANSI lumens, making it functional in rooms with ambient light. The projector's typical contrast ratio is 3,000,000:1, which provides definition between light and dark areas of the picture. Designed for professional use, it supports a native 16:9 aspect ratio and is compatible with HDR10 content for an expanded dynamic range. It includes multiple preset modes, such as Presentation and sRGB, to adapt to various content types.

A key characteristic of this model is its fixed short-throw lens, which has a throw ratio of 0.496. This design allows the projector to create a large image, from 70 to 300 inches, while positioned close to the projection surface. The laser light source is rated for a service life of 20,000 hours in standard operation and can extend to 30,000 hours in economic mode, which reduces the frequency of maintenance. For audio, the unit is equipped with a single 15W built-in speaker and a standard 3.5 mm audio output jack for connecting to external sound systems.

Installation flexibility is accommodated through support for both desktop and ceiling mounting. The projector features ±30° keystone correction on both the horizontal and vertical axes, allowing for image alignment when the unit cannot be placed perpendicular to the screen. Connectivity options include two HDMI 2.0b ports, two USB 2.0 Type-A ports, and an Ethernet LAN port for network integration and management. The device operates at a noise level of 30 dB in standard mode and 24 dB in economic mode, and comes with an included remote control and power cable.
