If having a superior gaming experience and better performance in bright rooms are important for you, consider the Sony A90K. It also offers a higher refresh rate which is beneficial for fast-moving content like sports. Meanwhile, the LG A2 is a more budget-friendly option with excellent picture quality for movies and good performance in dark rooms. However, be aware that its sound system is less powerful than the Sony's, and with a lower refresh rate, it may not handle fast-paced action as smoothly. Both TVs have OLED screens renowned for their deep blacks and wide viewing angles. If gaming and bright-room viewing aren't as critical for you, the LG A2 could provide a great viewing experience at a lower cost. Give Feedback

Techradar
Al Griffin | August 2022
"Movie fans will find a lot here to love, and the A2 series’ low prices compared with other OLED TVs will keep their wallets happy. Images had the deep blacks and detailed shadows typical of the best 4K TVs, while colors looked both fully saturated and clean. Also, the A2’s out-of-box picture performance in Filmmaker mode was mostly accurate, requiring only slight adjustments to optimize brightness, color, and contrast."
