Choosing between the LG G1 and the Sony A90J OLED TVs involves considering your preferences and viewing habits. If gaming is a priority, the LG G1 boasts slightly better gaming performance, offering a faster response time, which is beneficial for fast-paced games. For sports, the Sony A90J has a slight edge with better motion processing, which is important for fast action and reducing blur. In dark rooms both perform similarly well thanks to their OLED panels that deliver perfect blacks, but for bright room viewing, the LG G1 has a higher reflections score, indicating it handles ambient light better. Both TVs come with four HDMI ports and support Dolby Vision and HDR10, catering well to movie lovers, but the Sony A90J comes with better sound quality out-of-the-box if a separate sound system is not an option. Both the LG G1 and Sony A90J are at the higher end of the price spectrum, with the LG G1 often being slightly more expensive, so if cost is a factor, the Sony might be the more economical choice. Both TVs were released in the same year and have similar features, so it comes down to whether gaming performance or sports viewing and sound quality are more important to you. Give Feedback
