Model overview based on user reviews  
The LG OLED55G4 55" TV is highly praised for its excellent brightness and magnificent display quality. Users appreciate the significant progress from previous models, such as the CX version, noting improvements in brightness and content viewing capabilities. The TV supports a wide range of content sources, including unofficial ones, and offers advanced features like voice control and AI-powered sound adaptation. It is equipped with a powerful sound system featuring Dolby Atmos and multiple audio decoders. However, potential buyers should be aware that some models, especially those shipped to Ukraine, may come without a stand for horizontal installation, being designed primarily for wall mounting. Overall, the LG OLED55G4 is considered a top-tier OLED TV, with only a few models like the Sony A95L being regarded as superior.

The TV is magnificent.

Excellent TV. Previously used the CX version — the progress is significant. Did not choose the C4 due to potential brightness issues in game mode.

The only downside for shipments to Ukraine: models, at least 55", in most cases come without a stand for horizontal surface installation — only with wall mounting (LW, not LS).
Brightness of the panel, the ability to view content from various sources (including not entirely official ones).
