Our Verdict
LG A1 OLED
Samsung QN90A QLED
The Samsung QN90A QLED and the LG A1 OLED are very different TVs, as they use different panel technologies, each with their own strengths and weaknesses. The LG is a better choice for watching movies in a dark room, as it displays perfect blacks with no blooming, and has better uniformity. The Samsung is a better choice for gaming or for watching TV in a bright room, though, as it has a faster refresh rate, it supports advanced gaming features like HDMI 2.1 and variable refresh rate technology (VRR), and it's significantly brighter.
