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."
