Our Verdict
Samsung QN800A 8k QLED
LG NANO99 8k 2021
The Samsung QN800A 8k QLED is better than the LG NANO99 8k 2021, but there are a few differences between them. The Samsung has a VA panel with a much better contrast ratio, but the local dimming feature is worse than the LG because there's intense blooming. On the other hand, the LG has an IPS panel with wider viewing angles, even if the Samsung has viewing angle technology to improve it a bit. The Samsung uses Mini LED technology that allows it to get much brighter, and it has better reflection handling. The Samsung has more gaming features, like VRR support and lower input lag with an 8k resolution, but the IPS panel on the LG has less black smearing with fast-moving objects. Even though they're both 8k TVs, the LG does a better job at displaying native 8k content because it doesn't have any dithering like on the Samsung.
