Our Verdict
Samsung QN900A 8k QLED
Samsung QN800A 8k QLED
The Samsung QN900A 8k QLED sits above the Samsung QN800A 8k QLED in Samsung's lineup. They're similar, but there are a few key differences. The QN900A has a slimmer construction with thinner bezels. It also has a better local dimming feature, but the QN800A gets a bit brighter overall in SDR and HDR and has a slightly faster response time.
