Our Verdict
Samsung QN900A 8k QLED
LG QNED99 8k
The Samsung QN900A 8k QLED is a bit better than the LG QNED99 8k. They use different panel types, so the Samsung has a higher contrast, but the LG has wider viewing angles instead. They each have Mini LED backlighting that's supposed to provide better control over the dimming zones, and they're both decent. The Samsung gets brighter, and it has more gaming features like VRR support. On the other hand, the LG doesn't show any upscaling issues that the Samsung does with 4k and 8k content, so it displays a perfect 8k image.
