[Mania] 4K Cinema in My Hands... 'LG CineBeam Cube' Targeting Cinema Enthusiasts

Premium Projector 'LG CineBeam Cube' Review

Tissue Box Size with Lightweight 1.49kg
Automatic Screen and Focus Adjustment... 4K High Resolution
Some Disappointments in Sound Quality and Remote Control

For those who want to create a home cinema despite limited space, or enjoy vivid content on a large screen in various locations, a new product has been released. It is LG Electronics' premium 4K projector, the 'LG CineBeam Cube.' I received the product and used it personally for two weeks.

The first impression of the LG CineBeam Cube was "sleek." With a silver metal body and a rectangular cuboid shape, it had an appearance worthy of an interior object. If you add the dedicated leather cover, it creates an even more luxurious atmosphere. It also protects against scratches, allowing worry-free use outdoors.

The product boasts a compact size comparable to a household mini tissue box and a light weight of 1.49 kg. The screen size can reach up to 120 inches (diagonal length approximately 305 cm). Despite the large screen, it maintains 4K UHD resolution, making it a product that captures both portability and performance.

The most notable feature is the automatic screen and focus adjustment. LG Electronics equipped the CineBeam Cube with Auto Keystone (distortion correction) and Auto Focus functions so users do not need to manually adjust the screen or image quality. This instantly eliminates the hassle of having to adjust the screen straight according to distance and angle. In practice, the screen size and horizontal alignment automatically adjusted according to the wall surface.

The product’s handle makes it easy to carry, but it can also be used as a stand to support the main body. It can rotate 360 degrees around the product, allowing free adjustment of the projection angle via the stand. Of course, the screen automatically adjusts according to the angle.

Another attractive point is that it can be used even in bright daylight. While it is not a full replacement for a TV, it offers high image quality and clear contrast even during the day compared to typical projectors. It supports a contrast ratio of 450,000:1, and features 'Dynamic Tone Mapping' technology that automatically adjusts contrast according to the content being displayed, providing deep and clear image quality. Additionally, it uses an RGB laser light source, which LG Electronics explains delivers more accurate colors and clearer, more vivid images even in bright environments compared to conventional lamp light sources. Screen mode settings such as movie mode, sports mode, and expert mode are also available, allowing customized viewing experiences.

Equipped with a built-in web OS, it can be used like a smart TV as long as it is connected to the internet. With accounts for Netflix, Disney+, TVING, Watcha, Apple TV, and YouTube, you can enjoy videos anywhere, making it very convenient. It also supports AirPlay 2 and Miracast for screen sharing with smartphones. Of course, it can be connected to various devices via HDMI ports.

A downside is the sound quality. The built-in sound is not rich, resulting in low volume and poor immersion. Even when the volume was raised to the maximum level of 100 in a room, the sound was only loud enough to be heard without being noisy. It seems advisable to use an additional Bluetooth speaker outdoors. If the distance between the projection surface and the product is far, there may be a sense of disconnection between sound and video, so a speaker is considered essential.

Another drawback is the lack of a built-in battery. The LG CineBeam Cube requires a power connection, which means you need to find an outlet, causing inconvenience. The provided power cable is also somewhat short. Although it can be used without an outlet by using an external battery, this needs improvement considering it is a model emphasizing portability.

The remote control design also did not seem to match the color and design of the main body. It felt somewhat inconsistent with the premium nature of the product. The remote control operation was also unsatisfactory because it only worked when held close to the back of the product, resulting in poor recognition.

The price is somewhat burdensome as well. The LG CineBeam Cube’s retail price is 1,390,000 KRW, which is definitely higher than entry-level models.

Nevertheless, for those who want to create their own movie theater regardless of place and time, the LG CineBeam Cube may be a choice you won’t regret.
