Our Verdict
Samsung Q80/Q80T QLED
LG GX OLED
The LG GX OLED is better overall than the Samsung Q80/Q80T QLED, but they have different panel types. The LG has an OLED panel, allowing it to individually turn off pixels, which results in an infinite contrast ratio and perfect black uniformity. It also has a near-instant response time and wider viewing angles, great if you have a large seating area. However, the Samsung gets brighter, so it's a better choice for well-lit rooms, and it doesn't have permanent burn-in risk like OLEDs.
