Editorial note
The LG 42LT55A stands out for its exceptional image quality, thanks to its Full HD resolution of 1920 x 1080 pixels and a high contrast ratio of 1300:1.

Additionally, the LED display technology ensures a brightness of 450 cd/m², allowing for excellent visibility even in varied lighting conditions. In terms of connectivity, this television is versatile with several ports, including HDMI, DVI, and USB, making it easy to connect to various multimedia devices. However, the limited number of HDMI ports (only one) may restrict the ability to connect multiple devices simultaneously. Regarding design, the LG 42LT55A features a modern and sleek black appearance, with VESA compatibility that allows for easy wall mounting, thus optimizing your interior space. Concerning audio, the various sound modes (Movie, Music, Standard) enhance the listening experience, but the audio power of 20 W may prove insufficient for total immersion in large rooms.
