Our Verdict
Samsung Q90/Q90T QLED
Samsung QN800A 8k QLED
The Samsung Q90/Q90T QLED is better overall than the Samsung QN800A 8k QLED. The main difference between the two is that the Q90T has a much better native contrast ratio and full-array local dimming feature, so it displays deeper blacks. The QN800A uses Mini LED backlighting, but there's too much blooming. The Q90T also has a quicker response time for smoother motion. The QN800A supports 8k signals, which the Q90T doesn't, but there's not much native 8k content available in 2021 anyways.
