Manual of product 55UF840V
Editorial note
The LG 55UF840V is a television that stands out for its exceptional picture quality thanks to its 4K Ultra HD resolution (3840 x 2160 pixels) and LG's Triple XD Engine image processing technology, offering enhanced colors and details. The PQI (Picture Quality Index) 1600 technology also improves the fluidity of images, ensuring a pleasant viewing experience, especially when watching moving content. Additionally, its varied connectivity with multiple HDMI and USB ports allows for easy connection of various multimedia devices, making it a versatile choice for users. However, the LG 55UF840V has some limitations. The lack of Smart TV features restricts access to applications and online streaming services, which may disappoint users looking to enjoy these options. Furthermore, the power of the built-in speakers, rated at 20 W, is relatively low and may not be sufficient to provide an immersive audio experience for demanding users. The absence of support for 3D technology may also disappoint those wishing to explore this type of content. Finally, while the power consumption in standby mode is low, the operating power could be optimized for users concerned about energy efficiency. In terms of design, the television features a modern and sleek white color, but the product's weight is not specified, making it difficult to assess its maneuverability and transport. The value for money is fair, but the lack of Smart TV features and limited audio power may not meet the expectations of some users. In summary, the LG 55UF840V is a good choice for those seeking superior picture quality and varied connectivity, but the limitations in smart features and audio power should be taken into account.Score details
