Our Verdict

LG NANO90 2020

LG NANO90 2021

The LG NANO90 2021 and the LG NANO90 2020 are both good TVs. The 2021 model improves in some areas, like the peak brightness, gradient handling, and build quality, and it also has a redesigned interface. The 2020 model displays a wider color gamut for HDR content, but not by much. Overall, the picture quality between each is very similar, and it's unlikely you'll notice any differences.
