Editorial note

The LG OLED77CS9LA stands out with its OLED technology, providing vibrant colors and exceptional contrasts that ensure an immersive viewing experience. With a 4K Ultra HD resolution and a refresh rate of 120 Hz, this television guarantees optimal display fluidity, particularly appreciated for watching movies and gaming. Its modern design, combined with easy installation thanks to the VESA standard, allows it to blend seamlessly into any type of interior. However, this model has some notable drawbacks. The lack of Smart TV features limits access to streaming applications and the Internet, which can be frustrating for users accustomed to these services. Additionally, the energy efficiency class is rated F for SDR and G for HDR, which could lead to higher energy costs compared to other more efficient models. Although the television is equipped with a built-in subwoofer, its total audio power of 20 W may not be sufficient to provide an immersive sound experience in large spaces. Finally, the size and weight of the LG OLED77CS9LA, which approaches 36 kg, can make installation difficult for one person, potentially requiring the help of a second person. Despite these few weaknesses, the Timeshift feature is a plus, allowing users to pause and resume the broadcast of TV programs, thus offering increased flexibility during viewing.
