Manual of product 28LF450B
Editorial note
The LG 28LF450B television stands out for its remarkably low power consumption, with only 23 W in operation and 0.4 W in standby, contributing to appreciable energy savings. Its HD image quality, with a resolution of 1366 x 768 pixels and a brightness of 300 cd/m², offers a pleasant viewing experience, even in varying lighting conditions. Additionally, the built-in speakers provide satisfactory sound, eliminating the need for an external audio system to enjoy your content. However, there are some drawbacks to consider. The lack of Smart TV features limits access to streaming apps and the Internet, which may discourage users looking for online content. Furthermore, while the resolution is adequate for a 28-inch screen, it may seem insufficient for those expecting higher image quality. The limited number of HDMI ports (only one) and the absence of Wi-Fi and Ethernet connectivity also restrict connection options, making it difficult to connect multiple devices simultaneously. In terms of design, the LG 28LF450B features a modern and sleek finish that fits well in various environments. Nevertheless, the audio power of 10 W may not be sufficient in noisy environments. Overall, the LG 28LF450B is a good choice for those seeking a basic television with low energy consumption and an appealing design, but it may not meet the expectations of demanding users in terms of connectivity and image quality.Score details
