LG's Cinebeam Ultra Short Throw (UST) projector will throw a huge image, with the brilliance and clarity of 4K UHD, at an incredibly short distance from the source. The 4K Sound Laser UST projector delivers 3000 Ansi lumen of brightness, a high-resolution screen, and a sound that befits the large screen. Most existing UST projectors have limited screen size due to the limitations in the depth of the rack and the wall height. The LG 4k cinebeam can be installed on a conventional rack, but it can also be installed freely in the standalone simple rack, which is provided as an accessory, to enjoy the maximum image size to the degree the wall size permits.
