Our Verdict
Samsung QN900A 8k QLED
Sony A90J OLED
The Sony A90J OLED is better than the Samsung QN900A 8k QLED. While it can't display an 8k signal like the Samsung, there isn't much 8k content yet. Plus, the Sony is an OLED, so it has a near-infinite contrast ratio that can display perfect blacks with no blooming. The Samsung uses a VA panel but has low native contrast. While it's improved heavily by local dimming, the local dimming feature produces noticeable blooming. The biggest advantage of the Samsung is that it gets significantly brighter, so it's a little better suited to very bright rooms.
