Manual of product 55UM777H0UA
Editorial note
The LG 55UM777H0UA television stands out for its exceptional picture quality, thanks to a 4K Ultra HD resolution (3840 x 2160 pixels) that offers an immersive viewing experience with precise details. The LG AI Picture Pro technology also helps optimize colors and details, ensuring an enhanced viewing experience. In terms of connectivity, this model is well-equipped with three HDMI ports and two USB ports, making it easy to connect to various multimedia devices. However, some drawbacks are worth mentioning. The lack of Smart TV features limits access to popular online apps and services, which may be a drawback for users looking for a connected television. Additionally, the LCD display technology, while effective, does not always compete with the picture quality of OLED or QLED screens, particularly in terms of contrast and colors. The weight of 18.2 kg can also make transport and installation difficult, especially for a single person. Regarding design, the LG 55UM777H0UA features a modern and sleek aesthetic, with a desktop stand included for seamless integration into various spaces. However, the lack of a DVI port limits connection options for some older devices, and the unspecified contrast ratio could suggest average display performance in certain lighting conditions. In summary, the value for money is reasonable, given the features offered. However, the points mentioned above should be considered before making a purchase decision.Score details
