Our Verdict
LG QNED90
Samsung QN90A QLED
Although they use different panel technologies, each with strengths and weaknesses, the Samsung QN90A QLED is much better than the LG QNED90. The Samsung has much higher contrast, significantly better black uniformity, and a better local dimming feature, meaning that it looks better in a dark room. The Samsung also has higher peak brightness and much better reflection handling, so it's better in a bright room, too.
