Our Verdict
Samsung QN900A 8k QLED
Samsung QN900B 8k QLED
The Samsung QN900B 8k QLED is a slight improvement over its predecessor, the Samsung QN900A 8k QLED. The QN900B has a higher max refresh rate, which is great for PC gamers, and it has a faster response time, so motion looks smoother with less blur around fast-moving objects.
