Our Verdict
Samsung QN800A 8k QLED
LG QNED99 8k
The Samsung QN800A 8k QLED and the LG QNED99 8k are both very good 8k Mini LED TVs. The Samsung has a higher native contrast because it has a VA panel, but the IPS-like panel on the LG has wider viewing angles. Even though the LG has a worse contrast, it's slightly better for watching movies because its local dimming feature is better and doesn't cause as intense blooming around bright objects. It also displays native 8k content without any artifacts, unlike the Samsung. However, the Samsung is better for bright room viewing because it has better reflection handling and gets bright. It also supports VRR, which the LG doesn't.
