LG Introduces CineBeam S (PU615U) Ultra-Compact 4K UST Projector

LG Electronics has announced the CineBeam S (PU615U), which is a compact ultra-short-throw projector. LG demonstrated an early version of the model this year at CES 2025. The CineBeam S combines 4K UHD resolution, smart features, and good sound quality in a compact package designed for portability and ease of use.

The CineBeam S arrives as part of LG’s broader effort to expand its projector lineup. With models like the CineBeam Q (HU710PB) and the new CineBeam S (PU615U), LG is emphasizing compact design, making it easy to enjoy a large-screen experience nearly anywhere. Feature and performance-wise, the new CineBeam S should be nearly identical to the award-winning CineBeam Q.

The notable difference is that the CineBeam S has an ultra-short-throw lens system, so the unit can project a large image even when positioned very close to the projection surface. The projector produces a 40-inch diagonal picture from just 3.2 inches away, and from 15.5 inches, it can deliver a 100-inch picture. The CineBeam S design eliminates the need for a long throw, which is particularly beneficial for users in apartments, dormitories, or multipurpose living spaces.

The CineBeam S stands out for its minimalistic appearance and extremely small footprint. Measuring just 4.3 inches by 6.3 inches by 6.3 inches and weighing 4.2 pounds, the projector is smaller than many competing UST models on the market.  Its metallic finish is intended to blend seamlessly with modern interiors, allowing it to function not only as a technology product but also as a design element.

The compact unit can be placed on a shelf, table, or other flat surfaces, making it accessible in spaces where larger projectors would be impractical. The projector’s size and weight make it easy to move the CineBeam S from one room to another, further expanding its utility.

To simplify setup, the CineBeam S features several auto-adjustment features. Auto Screen Adjustment is designed to quickly align and sharpen the projected image, reducing the need for manual fine-tuning. For users who want more control, Screen Scaling and Shifting allow for changes to image size and placement without physically moving the projector. Another noteworthy inclusion is Wall Color Adjustment, which compensates for projecting onto surfaces that are not pure white. These features collectively aim to make the CineBeam S as user-friendly as possible, particularly for casual owners who may not have prior experience with projectors.

In terms of performance, the CineBeam S produces native 4K UHD resolution with a pixel count of 3,840 by 2,160. Its advanced RGB laser light engine allows the projector to achieve coverage of up to 154 percent of the DCI-P3 color gamut, a specification that indicates its ability to deliver highly saturated and accurate color reproduction.

The CineBeam S has a rated brightness of 500 ANSI lumens, which is comparable to other compact lifestyle projectors, such as the CineBeam Q (HU710PB).  This is enough brightness to produce crisp and clear images on an 80” screen in dark spaces and under low to moderate ambient light. Due to its dynamic contrast ratio of 450,000:1, the unit should be able to display deeper blacks and stronger separation between bright and dark areas of the image, which is particularly important for HDR content.

The CineBeam S utilizes LG’s smart TV platform, webOS, which is found in LG’s highly regarded smart TVs. The webOS allows for intuitive navigation and content discovery, streamlining the process of selecting movies, shows, or music. In addition to its built-in software ecosystem, the projector provides multiple connectivity options. A physical HDMI input and dual USB-C ports support external players, storage devices, and accessories.

Wireless connectivity is also available through AirPlay 2 for Apple devices and Screen Share for other smartphones, tablets, and PCs. This combination of wired and wireless options ensures compatibility with a wide range of sources. While CineBeam S includes a remote control, the projector is compatible with the LG ThinQ smartphone app, allowing owners to operate it directly from their mobile devices.

CineBeam S is equipped with built-in stereo speakers that support virtual Dolby Atmos, which is a step up from the CineBeam Q. The inclusion of Atmos processing provides a sense of spaciousness and immersion beyond traditional stereo playback, although the small enclosure size will naturally limit the unit’s bass output. The projector’s ability to function as a standalone entertainment system may appeal to users seeking a portable, all-in-one solution. For those who want to expand the audio experience, the included preorder bundle with the LG S40TR soundbar offers an easy path to higher-quality sound integration.

While CineBeam S includes a remote control, the projector is compatible with the LG ThinQ smartphone app, allowing owners to operate it directly from their mobile devices.

The combination of small size, premium design, and straightforward usability reflects LG’s intent to position the CineBeam S as a lifestyle product rather than a traditional high-end projector. Unlike larger models that target home theater enthusiasts with dedicated projection rooms, the PU615U is intended for consumers who want flexibility and convenience in compact living spaces.

The LG CineBeam S (PU615U) can transform a dorm room, studio apartment, or small living room into a functional home theater without the space and installation demands of conventional projectors. The portability factor also opens possibilities for use in multiple locations, allowing owners to set up temporary viewing areas when needed.

With this package, LG is highlighting the CineBeam S as both a stylish design piece and a functional home entertainment device, offering a balance of form, function, and price accessibility.

The introduction of the CineBeam S underscores LG’s commitment to developing projectors that address the varied needs of modern consumers. While higher-output models in the CineBeam line cater to enthusiasts seeking dedicated theater performance, the PU615U serves as an example of how ultra-short-throw projection can be adapted to fit everyday lifestyles.

For those who want a compact and stylish projector that delivers 4K resolution, smart functionality, and a big-screen experience without the complexity of traditional systems, the CineBeam S is a compelling option in the growing segment of lifestyle-oriented display solutions.

Priced at $1,299, the projector is available for preorder now at LG.com. Customers who reserve a unit before October 5 will also receive an LG S40TR soundbar, valued at $279, as part of a promotional bundle.
