Manual of product 42LQ640H
Editorial note
The LG 42LQ640H is a television that offers exceptional picture quality thanks to its Full HD resolution of 1920 x 1080 pixels and a dynamic contrast ratio of 1000000:1, ensuring deep blacks and bright whites. Its 42-inch screen with a wide viewing angle of 178° allows for an immersive and comfortable viewing experience from various spots in the room. Additionally, the built-in speakers with Dolby Digital audio decoders provide a quality sound experience. In terms of energy consumption, this model stands out for its low usage in standby mode, at only 0.5 W, contributing to energy savings and a reduced environmental impact. Its modern black design and VESA compatibility make installation on wall mounts easy, thus optimizing space. However, the LG 42LQ640H has some limitations. It does not support 3D technology, which may disappoint fans of immersive content. Furthermore, this model is not a Smart TV, which restricts access to streaming apps and the Internet. The response time of 42 ms may also pose a problem for gamers, resulting in slight display lag. Finally, the sound power of 10 W may not be sufficient in larger or noisier spaces, and the lack of USB 3.0 ports limits data transfer speeds. Overall, the LG 42LQ640H offers good value for money, but its features are basic and may not meet the expectations of all users. Performance is satisfactory for regular use, while the user experience is generally positive, despite some limitations in connectivity and entertainment.Score details
