BenQ LK830ST Short Throw DLP 4K UHD 4000 ANSI lm Laser Projector, Black

The BenQ LK830ST is a short-throw projector that utilizes DLP technology to produce a native 4K UHD (3840x2160) resolution. With a brightness of 4000 ANSI lumens and a dynamic contrast ratio of 3,000,000:1, it is engineered for use in well-lit professional environments such as conference rooms and classrooms. The unit supports various video modes and is compatible with High Dynamic Range (HDR10 and HLG) content for enhanced color depth. Connectivity options include two HDMI ports, two USB 2.0 ports, and an Ethernet LAN port for network integration.

A primary component of this model is its laser light source, which has a service life of up to 30,000 hours, reducing long-term maintenance. The projector's 0.496 throw ratio allows it to project a large image from a short distance, a functional benefit for smaller spaces. Installation is facilitated by ±30 degrees of horizontal and vertical keystone correction, in addition to vertical and horizontal lens shift capabilities. The operational noise level is rated at 30 dB in standard mode and 24 dB in economic mode.

Designed for either desktop or ceiling placement, the BenQ LK830ST measures 279.2 mm in width and weighs 3600 g. The projector includes a single 15W built-in speaker for audio playback and a headphone output for connecting to external sound systems. A fixed zoom lens is standard, and the unit comes with a remote control and power cable for setup. Its feature set is oriented toward business and presentation applications that require consistent and detailed visual output.
