The LG NANO80 2020 is a lower-midrange 4k TV with okay overall performance. It's a larger variant of the LG NANO81 and offers similar performance and features, except there isn't any local dimming. It has an IPS panel with fairly wide viewing angles, but that comes at the cost of its low contrast ratio, and blacks appear gray when viewed in the dark. Despite missing many gaming features, it has a decent response time and incredibly low input lag, so it's a good choice for casual gaming. Unfortunately, HDR content doesn't pop how it should because it doesn't get bright in that mode, but it displays a wide color gamut for HDR content. Lastly, LG's WebOS is easy-to-use and the LG Content Store has a great selection of apps available to download.

Our Verdict

6.6 Mixed Usage

The LG 75NANO80UNA is an okay TV for most uses. It's decent for watching TV shows or sports and performs best in wide seating arrangements due to its wide viewing angles. It's good for gaming thanks to its incredibly low input lag and decent response time. However, it's not a good choice for watching movies in dark rooms because it has a low contrast ratio and there's no local dimming feature.

Pros
  • Fairly wide viewing angles.
  • Decent reflection handling.
  • Incredibly low input lag.
Cons
  • Low contrast ratio.
  • No local dimming feature.
  • Poor HDR peak brightness.
5.9 Movies

The LG 75NANO80UNA is disappointing for watching movies. It has an IPS panel with a low contrast ratio and no local dimming feature, so blacks appear closer to gray when viewed in the dark. Fortunately, it upscales 1080p content well and removes 24p judder from Blu-rays.

Pros
  • Removes judder from native 24p sources.
Cons
  • Low contrast ratio.
  • No local dimming feature.
7.3 TV Shows

The LG 75NANO80UNA is decent for watching TV shows. It has fairly wide viewing angles and the image remains accurate even if you walk around while watching. It also upscales lower-resolution content without any issues. Sadly, it doesn't get very bright and has only decent reflection handling, so it's best to avoid using it in well-lit rooms.

Pros
  • Fairly wide viewing angles.
  • Decent reflection handling.
Cons
  • Doesn't get bright enough to combat glare.
7.0 Sports

The LG 75NANO80UNA is decent for watching sports. It has a decent response time that results in minimal motion blur, but you may notice image duplication due to the backlight's flicker. It has wide viewing angles if you want to watch the game in a wide seating arrangement. Unfortunately, it's best to avoid using it in a bright room as it has a disappointing peak brightness and only decent reflection handling.

Pros
  • Fairly wide viewing angles.
  • Decent reflection handling.
  • Decent response time.
Cons
  • Doesn't get bright enough to combat glare.
  • Visible dirty screen effect in the center.
6.5 Video Games

The LG 75NANO80UNA is good for video games. It has incredibly low input lag and a decent response time, but you may notice image duplication because of the backlight's 120Hz flicker. Unfortunately, it lacks many features like variable refresh rate support or a Black Frame Insertion feature.

Pros
  • Decent response time.
  • Incredibly low input lag.
Cons
  • Low contrast ratio.
5.6 HDR Movies

The LG 75NANO80UNA is disappointing for watching HDR movies. It displays a wide color gamut for HDR content and has decent gradient handling, but it doesn't get bright enough to make highlights pop. Also, it has a low contrast ratio and there's no local dimming, so it doesn't perform well in dark rooms.

Pros
  • Displays wide color gamut.
Cons
  • Low contrast ratio.
  • No local dimming feature.
  • Poor HDR peak brightness.
6.7 HDR Gaming

The LG 75NANO80UNA is okay for HDR gaming, mainly due to its good gaming performance. It has incredibly low input lag and a decent response time for a responsive gaming experience. It displays a wide color gamut for HDR content, but it has low peak brightness, no local dimming feature, and a low contrast ratio.

Pros
  • Decent response time.
  • Incredibly low input lag.
  • Displays wide color gamut.
Cons
  • Low contrast ratio.
  • No local dimming feature.
  • Poor HDR peak brightness.
8.0 PC Monitor

The LG 75NANO80UNA is good to use as a PC monitor. It has fairly wide viewing angles, so the image remains accurate if you sit close. It has incredibly low input lag and displays chroma 4:4:4, which is important for reading text. Unfortunately, even though it has decent reflection handling, it doesn't get bright enough to combat glare in well-lit rooms.

Pros
  • Fairly wide viewing angles.
  • Incredibly low input lag.
  • Displays chroma 4:4:4.
Cons
  • Doesn't get bright enough to combat glare.
  • 6.6 Mixed Usage
  • 5.9 Movies

Differences Between Sizes And Variants

We tested the 75 inch LG NANO80 2020, which is the only size available for this model in the United States and is only sold at certain retailers for Black Friday. This TV is a variant of the LG NANO81, which has a center-mounted stand and a local dimming feature. There are other sizes of the NANO80 available in Canada and Europe, which are listed below, and for the most part, we expect our results to be valid for the 49 inch, 55 inch, and 65 inch variants. The LG NANO79 is sold in Europe and seems to be a similar TV, but with a center-mounted stand as well.

If someone comes across a different type of panel or if their TV doesn't correspond to our review, let us know and we'll update the review. Note that some tests, such as the gray uniformity, may vary between individual units.

The unit we tested was manufactured in September 2020 and you can see the label here.

Compared To Other TVs

The LG NANO80 2020 is an okay overall TV and provides alright performance for its price and size. However, there are better options out there, especially if you don't need wide viewing angles and prefer something with better contrast, such as the Samsung TU6980. Also see our recommendations for the best TVs for Xbox Series X, the best TVs for PS5, and the best 4k TVs.

LG NANO75 2021
43" 50" 55" 65" 70" 75" 86"

The LG NANO80 2020 and the LG NANO75 2021 are nearly identical, and most differences between them can be attributed to panel variance. The NANO75 2021 has better gradient handling, though, and it supports eARC.

Samsung Q60/Q60T QLED
43" 50" 55" 58" 65" 75" 82" 85"

The Samsung Q60/Q60T QLED is much better than the LG NANO80 2020, although they use different panel types with different advantages. The Samsung uses a VA panel with a much better contrast ratio, gets significantly brighter, has better color accuracy, and better uniformity, but this may vary between units. The LG, however, has an IPS panel with wide viewing angles, and it also has a quicker response time for less motion blur.

LG NANO81
55" 65" 75"

The LG NANO81 is better than the LG NANO80 2020. The NANO81 gets brighter, has much better reflection handling, and it has a local dimming feature, but it doesn't perform well. However, the NANO80 has a quicker response time and much better out-of-the-box color accuracy, but this may vary between units.

LG NANO90 2020
55" 65" 75" 86"

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.

TCL 4 Series/S435 2020
43" 50" 55" 65" 75" 85"

The LG NANO80 2020 is slightly better than the TCL 4 Series/S435 2020, but they have different panel types. The LG has an IPS panel with wide viewing angles, it gets much brighter, displays a wide color gamut, has lower input lag, and a much quicker response time. However, the TCL has a VA panel with a better contrast ratio and it has much better gradient handling.

LG UN6970
75"

The LG UN6970 is slightly better than the LG NANO80 2020. The UN6970 gets much brighter, has wider viewing angles, and a quicker response time. However, the NANO80 displays a wide color gamut and has better color accuracy.

Samsung TU8000
43" 50" 55" 65" 75" 85"

The Samsung TU8000 is better overall than the LG NANO80 2020, although they use different panel types. The Samsung has a VA panel that provides a better contrast ratio and better black uniformity. It also gets a bit brighter and has a Black Frame Insertion feature. However, the LG has an IPS panel with wider viewing angles, it has a quicker response time, and it displays a wide color gamut for HDR content, which the Samsung doesn't.

LG CX OLED
48" 55" 65" 77"

The LG CX OLED is significantly better than the LG NANO80 2020. The LG has an OLED panel that individually turns off pixels, resulting in an infinite contrast ratio and perfect black uniformity. It also has gaming features like VRR support and a near-instantaneous response time. However, the LG NANO80 2020's LED panel doesn't have the risk of long-term burn-in associated with OLEDs.

Samsung TU6980
70" 82"

The Samsung TU6980 is better than the LG NANO80 2020, but they have different panel types. The Samsung has a VA panel and displays much deeper blacks. It also gets brighter, has a quicker response time, and a  Black Frame Insertion feature. However, the LG has an IPS panel with wider viewing angles, it displays a wide color gamut, and has better gradient handling.

The LG 75NANO80UNA has a decent, yet simple, design. It doesn't have a premium look like other models in the NanoCell Series, such as the LG NANO81, and looks more like the LG UN7000. It has somewhat thick bezels and the stand consists of two feet instead of the center-mounted stand found on higher-end models.

Design
Stand

The stand is made of metal feet and it's almost as wide as the TV itself, so you need a large table to place it on. Sadly, the feet can't be placed inwards to accommodate smaller tables. The stand supports the TV well, but there's still some wobble.

Footprint of the 75" inch TV: 62.9" x 13.1".

The back of the TV is made of smooth metal and doesn't have any patterns etched into it. Sadly, there's no cable management.

The LG 75NANO80UNA has disappointing SDR peak brightness. It maintains its brightness consistent across different content, but it doesn't get bright enough to combat glare in well-lit rooms. If you want something brighter, check out the LG UN6970.

We measured peak brightness after calibration in the 'Expert (Dark Room)' Picture Mode with Backlight at its max and Color Temperature set to 'Warm2'. If you want something brighter, then consider the LG QNED80.

The HDR peak brightness is poor. It doesn't get bright enough to make vivid colors stand out in HDR and small highlights are dim due to the TV's frame dimming.

We measured HDR peak brightness in the 'HDR Cinema' Picture Mode with Backlight and Contrast each at their max and Color Temperature set to 'Warm2'. Once again, we got the brightest image possible with these settings, as seen in the 10% window.

The out-of-the-box accuracy is good, but this may vary between units. Most colors and white balance are only slightly inaccurate, and it shouldn't be too noticeable for most people. However, the color temperature is much colder than our 6500K target, and gamma seems to follow a 2.0 target instead of 2.2, so most scenes are brighter than they should be.

The LG 75NANO80UNA has a good wide color gamut for HDR content. It has excellent coverage of the commonly-used DCI P3 color space, but its coverage of the wider Rec. 2020 color space is limiting.

The EOTF follows the target PQ curve fairly well until it rolls off at its peak brightness. The image is similar in 'Game' mode, as you can see in this EOTF.

If you find HDR too dim and want the brightest image possible, enable Dynamic Tone Mapping, set Dynamic Contrast to 'High' with Brightness and Contrast at their max. This results in a slightly brighter image, as you can see here.

The LG 75NANO80UNA has decent gradient handling. The most noticeable banding is with grays and greens, and there's some with reds and blues as well. Setting the Smooth Gradation feature to 'Medium' or 'High' doesn't affect the test pattern, but it really smooths out gradients in real content, at the cost of losing fine details. The newer LG NANO75 2021 has much better gradient handling.

The LG 75NANO80UNA supports most common resolutions at 60Hz, including 1440p. It supports chroma 4:4:4 at any resolution, which is important for reading text if you're going to use it as a PC monitor. Set the icon for the input you're using to 'PC' in the Home Dashboard to display chroma 4:4:4. For full-bandwidth signals, simply enable HDMI Ultra HD Deep Color.

The LG 75NANO80UNA only supports Dolby Digital audio formats via ARC or optical but doesn't support any DTS formats. For ARC to work, set HDMI Input Audio Format to 'Bitstream' for the HDMI input you're using, Digital Sound Out to 'Pass Through', and Sound Out to HDMI ARC in the sound settings. If you want a TV with better support for audio passthrough and eARC support, check out the LG NANO75 2021 instead.

This TV has an alright frequency response, and it has a more-balanced sound profile than the LG NANO81. It doesn't produce much bass and doesn't get very loud, and you may notice compression artifacts at its max volume. There's a 'Digital Room Correction' feature in the 'AI Service' menu.

The distortion performance is okay. There's some minor distortion at moderate listening levels, and it gets more noticeable at its max volume. However, this depends on the content and not everyone may hear it.
