Our Verdict
Samsung Q90/Q90T QLED
Samsung Q80/Q80T QLED
The Samsung Q90/Q90T QLED and the Samsung Q80/Q80T QLED are very much alike, as they offer identical features. The biggest difference is in terms of performance, where the Q90T performs slightly better than the Q80T. The Q90T has a higher contrast ratio and peak brightness, and it has much better gradient performance, resulting in less banding. However, the Q80T has better color accuracy and black uniformity, although these could be due to panel variance.
