The LG ProBeam BU50NST is a compact, 5,000-lumen projector designed for various ProAV applications. The projector’s powerful laser light source is rated for up 20,000 hours allowing years of near maintenance-free operation.

With 5,000 lumens of output, it is bright enough to be utilized in many enterprise, hospital, museum, and education environments.

The BU50NST offers 1.6x lens zoom along with horizontal and vertical lens shift, which is rare on DLP projectors at this price point. Combined with the 12-point warping function, these features reduce image distortion and allow precise alignment with the screen.

The 4K resolution delivers the highly detailed images often required in corporate and healthcare environments. It even includes a DICOM picture mode. In addition to a USB input, HDBaseT™ compatibility allows a single CAT6 cable to carry 4K signals long-distances to the BU50NST.

The ProBeam BU50NST is powered by LG’s WebOS with smart features designed for business and education purposes like (Miracast®) wireless screen mirroring, Wi-Fi, and a web browser.
