Our Verdict
Samsung QN800A 8k QLED
Samsung QN900B 8k QLED
The Samsung QN900B 8k QLED is slightly better than the Samsung QN800A 8k QLED. The QN900B has a much better local dimming feature, with significantly less blooming around bright objects. The QN900B is also better for gaming, especially for PC gamers, as it has a higher max refresh rate and better motion handling, with less blur around fast-moving objects.
