Our Verdict
LG C1 OLED
Samsung QN900A 8k QLED
The LG C1 OLED is very different from the Samsung QN900A 8k QLED since they use different panels. The Samsung is an 8k TV with a VA panel, while the LG is a 4k OLED. That said, 8k content still isn't widespread, so it's not worth the investment at this point. The LG also has a near-infinite contrast ratio, allowing it to produce deep blacks with no blooming, while the Samsung has a surprisingly low native contrast ratio and has some issues with blooming. All in all, the LG offers more value.
