Our Verdict
Samsung QN900A 8k QLED
Samsung QN90A QLED
The Samsung QN90A QLED and the Samsung QN900A 8k QLED are high-end TVs in Samsung's Neo QLED series, which use Mini LED backlighting. While the QN900A is an 8k TV with a price tag to match, the 4k QN90A performs better overall. The QN90A has a higher native contrast ratio and a better local dimming feature. It also gets even brighter in both SDR and HDR.
