The LG G3 OLED is a high-end TV that might come at a significantly higher cost compared to the Sony A80J OLED. If having the latest model with higher peak brightness that may be advantageous for well-lit rooms is important to you, the LG G3 seems like a good option. However, the Sony A80J, while being an older model, offers exceptional picture quality and built-in speaker system performance that rivals newer TVs. If looking for a balance between cost and high performance for movies, gaming, and everyday TV watching in both bright and dark rooms, the Sony A80J could offer considerable savings without compromising much on quality. The LG G3 does not come with a regular stand and includes a sleek flush wall mount instead, which might be an issue if wall mounting isn’t your preference, while the Sony A80J provides flexible stand options for different setups.

Kob Monney | July 2022
"For home cinema fans the Sony A80J puts in a talented HDR performance, while daytime TV viewers benefit from its impressive upscaling and motion processing. Whites are portrayed in a clean and bright manner and black levels are strong, making for a very satisfying and consistent HD upscale. The A80J’s motion processing is hugely impressive. The Sony A80J takes content at any resolution and makes it look great, its motion skills are class-leading and its HDR performance boasts plenty of detail, contrast and expressive colours."
