LG Electronics is now selling its compact CineBeam 4K Ultra HD laser projector, model HU80KA, through select retailers in the United States, the company said Monday.
The “4K Ultra HD” projector, which carries a $2,999.99 suggested retail price, is based on Texas Instruments’ eXpanded Pixel Resolution (XPR) pixel-shifting Digital Micromirror Device (DMD) DLP technology, which doesn’t actually have a native 3840 x 2160 4K micromirror chip, but instead rapidly shifts back and forth an optical actuator (a glass pane), which is placed in the light path between the DMD and the lense, a second half-frame of video by one-half pixel up and one-half pixel over to the right. LG told us the HU80KA is using TI’s 0.47-inch DMD, which produces a full 8 million pixels on screen at one time.
Because each of the pixels perceived by the eye on screen at one time is individually addressable, the system meets the Consumer Technology Association’s definition of a 4K display.
Meanwhile, the projector’s laser light engine uses an LD plus phosphor color wheel to generate different colors. The laser light source has a listed life expectency of 20,000-plus hours without the need to change any bulbs. Peak brightness is listed as 2,500 ANSI Lumens for a screen size of up to 150-inches measured diagonally.
The throw distance is 14.5 feet for 150-inches; 9.5 feet for 100 inches and 3.6 feet for 40 inches.
The LG CineBeam 4K Laser Projector, which made its debut at CES 2018 in January, also features a compact, upright design, which is a departure from some other 4K projector technologies that necessitate large, heavy and expensive cabinets with large footprints. This enables easily transporting the projector from room to room for playback flexibility.
The projector includes a carrying handle and Auto Cord feature to make it even more more portable.
LG said it uses a hinged Mirror Reflector at the top of the projector to project the image up into the mirror which reflects it out onto the projection surface in standing vertical placement applications. This mirror also serves as a lens cover to protect the projector from dust when stored. The company significantly kept down the size and weight of the CineBeam 4k projector using an I-shaped engine design, which allows the projection of high-quality images from a variety of placement applications including on the floor, monted on the wall or suspended from the ceiling.

LG said the projector also supports specially encoded high-dynamic-range (HDR) videos based on the HDR 10 static metadata profile, to present a wider range of contast (150,000:1) with more vivid and natural-looking colors than standard dynamic range content.
For audio, the CineBeam 4K incorporates two 7W + 7W stereo speakers. It can also be connected to a soundbar.
Connectivity includes two HDMI ports including 2.0a/HDCP 2.2 support, 1 USB 3.0 port 1 USB 2.0 port, 1 RJ 45 connection, 1 digital optical audio output, MiraCast screen sharing, Bluetooth audio connectivity, and Wi-Fi connectivity for DLNA devices and the embedded LG Smart TV webOS platform and Magic Remote bringing easy app navigation with access to Netflix, Hulu, YouTube, Channel Plus and others.
“The LG CineBeam 4K Laser Projector is a true game changer in the projector market,” said Tim Alessi, head of home entertainment product marketing at LG Electronics USA. “Portability and versatility combined with 4K technology delivers the ultimate large-screen home cinema experience in a compact size. This projector will lead the way in changing how consumers view 4K content in any room at home.”
