LG Electronics has announced the addition of another short-throw projector to its lineup, designed for business applications. The LG ProBeam BU53RG short-throw 4K UHD projector replaces last year’s LG ProBeam BU53PST, and is said to run the webOS 6.0 Signage operating system – a powerful, web-based platform for digital signage with advanced features that enable it to be used as part of a network made up of multiple displays.


Last year’s LG ProBeam BU53PST was highly rated for its extraordinary value and powerful specifications, with brightness rated at an impressive 5,000 lumens. Together with its 4K resolution, it also sported a maintenance-free laser + phosphor light engine, HDR compatibility and built-in WiFi with an integrated browser. Those features are often missing, even on pricier competitors.

The updated LG ProBeam BU53RG is more or less identical to the BU53PST, both in terms of its aesthetics and its specs. Like its predecessor, it comes with tons of features that make it well suited to applications such as corporate meeting rooms, advertising scenarios and even golfing simulators.

It notably has the ability to throw up a large, high-resolution image in tight spaces, thanks to the 0.94 to 1.14 throw ratio. It’s a multi-function powerhouse, with feature such as 4K UHD resolution, 5,000 lumens brightness, lens shift control at up to 20% horizontal and 50% vertical, a 1.2x zoom capability and support for multiple aspect ratios, including 16:9, 16:10, 16:6 and 21:9.

With its 3,000,000: contrast ratio, users can be sure that the images it generates will be super clear and detailed, and the unit is said to be good for at least 20,000 hours of high-performance use at full brightness. In terms of audio, it comes with a pair of integrated 5-watt stereo speakers and has HDMI ARC for connection to an AV receiver, plus Bluetooth audio out with sync controls. There’s also a native MiraCast screensharing capability that enables easy connectivity to mobile devices.

As for outputs, there are two HDMI slots, two USB ports, one RJ45 port, a RS-232C port and a 3.5mm audio jack, enabling it to support a range of peripherals and control systems.

What really sets the LG ProBeam BU53RG apart from its predecessor is the inclusion of the webOS 6.0 Signage platform, which first appeared on the company’s BU70QGA model, its 7,000-lumens flagship projector. The webOS 6.0 Signage software supports numerous kind of commercial applications, including the preinstalled LG SuperSign content management software. With this, users can enable content distribution across multiple LG displays and projectors, including its commercial flat panel displays. It also provides access to various popular third-party signage apps via its web store.

The LG ProBeam BU53RG is available now, priced at £4,299 in the U.K., €4,299 in the EU and $4,199 in the U.S., and comes with a three-year warranty, the company said.
