Our Verdict
LG BX OLED
Samsung Q80/Q80T QLED
The LG BX OLED is a better overall than the Samsung Q80T QLED. Thanks to its OLED panel, the LG has an infinite contrast ratio, wider viewing angles, and a near-instant response time. The Samsung does get brighter, has a lower input lag, and doesn't have the risk of permanent burn-in. That said, burn-in shouldn't be an issue if you watch varied content, so all in all, the LG is a better choice if you want stunning picture quality.
