The LG NANO90 2020 is a good overall TV in LG's NanoCell series. It has an IPS panel with fairly wide viewing angles, but that comes at the cost of a low contrast ratio and mediocre black uniformity. It has a full-array local dimming feature which improves the contrast a bit, but its performance is quite disappointing. Gamers should appreciate its great response time, low input lag, and 120Hz panel. It also has variable refresh rate (VRR) support to reduce screen tearing. Although it doesn't get very bright, it has impressive reflection handling, so you shouldn't have any issues placing it in moderately-lit rooms. Sadly, HDR content doesn't look very good because it doesn't get bright enough to truly bring out highlights.

Popular TV Comparisons
The LG NANO90 2020 is a good overall upper-mid range TV. Its IPS panel provides fairly wide viewing angles, although they're not as wide as some other TVs. It has a full-array local dimming feature, which is a nice touch, but it doesn't produce the same deep blacks as VA panel TVs. Overall, it's a slight upgrade over its predecessor, the LG SM9000 and most people should be happy with this TV. Also see our recommendations for the best LED TVs, the best 70-75-77 inch TVs, and the best TVs for watching TV shows.
The LG NANO90 2020 is a bit better overall than the Samsung Q60T, but they have different panel types. The LG has an IPS panel with wider viewing angles. It also has a 120Hz refresh rate with VRR support to reduce screen tearing, and the response time is much quicker on the LG, providing a better gaming experience. However, the VA panel on the Q60T has a much better contrast ratio, and it gets much brighter, making it a better choice for dark room viewing.
The Hisense H8G is a bit better overall than the LG NANO90 2020, but they have different panels. The Hisense has a VA panel, resulting in an excellent contrast ratio and narrow viewing angles. It also supports HDR10+, gets brighter, and has a lower input lag. The IPS panel on the LG has a low contrast ratio and wide viewing angles. Also, the LG has better reflection handling, a higher refresh rate, and quicker response time.
The LG CX OLED is a significantly better TV than the LG NANO90 2020. The CX can individually turn off pixels, which produces extremely deep blacks and it has perfect black uniformity. This TV also has a near-instantaneous response time, wider viewing angles, better color accuracy, a wider color gamut, and better reflection handling. However, the NANO90 has less stutter due to its slower response time and it doesn't have the risk of permanent burn-in.
The LG NANO90 2020 is much better than the LG NAN080 2020. The NANO90 gets brighter, has a full-array local dimming feature, VRR support, and a 120Hz panel. It also has a quicker response time and better reflection handling. However, the NANO80 has a lower input lag and slightly better gradient handling.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
