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.

Our Verdict

7.5 Mixed Usage

The LG 75NANO90UNA is a good overall TV. With its IPS panel, it provides fairly wide viewing angles, which is ideal for watching TV shows, sports, or using it as a PC monitor. It's also great for gaming because it has a quick response time, low input lag, and VRR support. It has a low contrast ratio and mediocre black uniformity, so it's not a good choice for watching movies or gaming in the dark. HDR content doesn't look great either, as it doesn't get bright enough to bring out highlights.

Pros
  • Fairly wide viewing angles.
  • Excellent low input lag.
  • Impressive reflection handling.
Cons
  • Low contrast ratio.
  • Doesn't bring out highlights in HDR.
  • Doesn't get very bright.
7.0 Movies

The LG 75NANO90UNA is decent for watching movies. Due to its IPS panel, it has a low contrast ratio. Luckily, it has a full-array local dimming feature that improves the contrast, but it doesn't handle transitions between the dimming zones well. This TV upscales 1080p content well and it can remove judder from any source.

Pros
  • Removes judder from any source.
  • Full-array local dimming feature.
Cons
  • Low contrast ratio.
  • Mediocre black uniformity.
7.7 TV Shows

The LG 75NANO90UNA is good for watching TV. It has fairly wide viewing angles, so you get an accurate image when viewed from the side, which is good if you tend to walk around while watching your favorite show. It has impressive reflection handling but doesn't get bright enough to combat glare in a well-lit environment. Also, it upscales lower-resolution content without any issues, such as from cable boxes.

Pros
  • Fairly wide viewing angles.
  • Impressive reflection handling.
Cons
  • Doesn't get very bright.
7.8 Sports

The LG 75NANO90UNA is very good for sports. It has a quick response time that results in smooth motion, and there's a Black Frame Insertion feature to improve clarity. It has fairly wide viewing angles and performs well in moderately-lit rooms because of its impressive reflection handling, but it doesn't get very bright. It doesn't have any issues upscaling 720p content from cable boxes.

Pros
  • Fairly wide viewing angles.
  • Impressive response time.
  • Impressive reflection handling.
Cons
  • Visible dirty screen effect.
  • Doesn't get very bright.
7.7 Video Games

The LG 75NANO90UNA is good for video games. It has a great response time, a Black Frame Insertion feature, and a really low input lag. It's not ideal for dark-room gaming because it has a low contrast ratio, but in bright rooms, it has impressive reflection handling. It also has VRR support to reduce screen tearing.

Pros
  • Excellent low input lag.
  • Impressive response time.
  • Full-array local dimming feature.
Cons
  • Low contrast ratio.
6.7 HDR Movies

The LG 75NANO90UNA is okay for HDR movies. It supports HDR10 and Dolby Vision, displays a wide color gamut for HDR content, but it doesn't get bright enough to truly bring out highlights. It also has a low contrast ratio and mediocre black uniformity, so it's not ideal for watching movies in the dark. However, it has a full-array local dimming feature that improves the contrast.

Pros
  • Removes judder from any source.
Cons
  • Low contrast ratio.
  • Doesn't bring out highlights in HDR.
7.8 HDR Gaming

The LG 75NANO90UNA is very good for HDR gaming, mainly due to its great gaming performance. It has a very low input lag and its quick response time results in minimal motion blur. It has VRR support to reduce screen tearing. Sadly, HDR content doesn't look good on this TV because it doesn't get bright enough to bring out highlights.

Pros
  • Excellent low input lag.
  • Impressive response time.
Cons
  • Low contrast ratio.
  • Doesn't bring out highlights in HDR.
8.5 PC Monitor

The LG 75NANO90UNA is an excellent choice to use as a PC monitor. It displays chroma 4:4:4 with a 1080p or 4k resolution, which is important for reading text. It has fairly wide viewing angles, so the edges of the screen don't look washed out if you sit too close. It has impressive reflection handling, but it doesn't get bright enough to combat glare in a well-lit environment.

Pros
  • Fairly wide viewing angles.
  • Excellent low input lag.
  • Displays proper chroma 4:4:4.
Cons
  • Visible dirty screen effect.
  • Doesn't get very bright.

The LG NANO90 2020 is an upper-mid range 4k LED TV in LG's 2020 NanoCell series. It replaces the LG SM9000, and it sits above the LG NANO85/NANO86 and below LG's 8k Series. The LG NANO91 in Europe appears to be the same TV but with a center-mounted stand. Its main competitors are the Sony X800H, Samsung Q70/Q70T QLED, and the Hisense H8G.

Style
Curved No

The LG 75NANO90UNA has an excellent design that's different from 2019's LG SM9000. It looks a lot like the LG NANO85 and it has thin bezels on three sides. It has two wide-set feet as its stand, somewhat of a downgrade from the stylish center-mounted stand on the SM9000. Overall, it's a simple-looking TV that doesn't stand out much.

Design
Stand

The stand is different from its predecessor, the LG SM9000. Instead of a center-mounted stand, it has two feet that sit at the edge of the TV, so you're going to need a wide table to place it on. There's enough space to put a soundbar in front of it too.

Footprint of the 75" TV: 56.9" x 14".

Update 08/17/2020: We confirmed the back panel is made out of metal, and not plastic, as we previously stated. The review has been updated.

The back is made out of smooth metal and it has a simple design. There are downward and side-facing inputs, and there are hooks on the feet that serve as cable management.

The LG 75NANO90UNA is fairly thin and if you wall-mount it, it won't stick out much, if at all.

Update 08/17/2020: We confirmed the back panel is made out of metal, and not plastic, as we previously stated. The review has been updated.

This TV has a decent build quality. It's made out of metal and plastic that feels cheap and there's nothing premium about it. Still, the overall build is solid and the TV is held together well. There's not a lot of wobble, especially for a TV of this size. Lastly, the inputs flex a bit, but this shouldn't be an issue for most people.

The contrast ratio isn't bad for an IPS panel TV, but this may vary between units. It's similar to other LG TVs we've seen in the past, but it's not as good as the LG NANO85. Still, blacks appear closer to gray, which is noticeable in a dark room. It has a full-array local dimming feature that improves the contrast ratio. If you want a TV with an exceptional contrast ratio, see the Samsung Q70/Q70A QLED.

The LG 75NANO90UNA has just okay peak brightness in SDR, very similar to the LG NANO85. It quickly loses brightness when large, bright areas cover the screen, which is likely caused by its Automatic Brightness Limiter (ABL). If you want a similar-performing TV that gets much brighter, then check out the Samsung Q80/Q80A QLED.

We measured the peak brightness after calibration on the 'Expert (Dark Mode) Picture Mode, with Brightness and Contrast set to 'Max', and Local Dimming on 'Medium'. The brightest the TV got was with these settings, as seen in the 10% peak window test.

The LG 75NANO90UNA has a full-array local dimming feature, but it's quite disappointing. When there are small, bright objects moving across the scene, the dimming zones don't transition quickly, and you see the transitions happening, which could be distracting. Also, since it's an IPS TV with a low contrast ratio, blacks still look gray. On the upside, it handles subtitles well as there isn't noticeable blooming. We recommend setting Local Dimming to 'Medium', but even with this setting, there are still issues as small light sources don't pop at all, and it crushes dark scenes.

Update 07/19/2021: We retested the local dimming feature in Game Mode based on user feedback. We found that the local dimming feature is disabled whenever FreeSync is in use from a native FreeSync source, like an AMD graphics card, but it works fine when connected to a G-SYNC source. This is most likely a bug, but we don't know for sure.

This TV has unremarkable peak brightness in HDR. Once again, the LG 75NANO90UNA loses brightness with large areas, as seen in the difference in brightness in the 10% and 100% peak window tests. This TV doesn't get bright enough to truly bring out highlights in HDR. If you want something brighter, check out its replacement, the LG NANO90 2021.

We measured the peak brightness before calibration on the 'Cinema' Picture Mode, with Brightness and Contrast set to 'Max', and Local Dimming on 'Medium'.

If you want the brightest image possible, use the 'Vivid' Picture Mode with Local Dimming set to 'Medium'. We were able to get 692 nits on the 10% peak window test, but even this peak brightness only lasted a few seconds before it dropped to about 320 nits.

The gray uniformity is just okay, but this may vary between units. The edges of the screen are visibly darker and there's some noticeable dirty screen effect in the center, which could be distracting while watching sports. The uniformity is much better in dark scenes.

The black uniformity is mediocre, but this may vary between units. Without local dimming, there's clouding throughout and visible backlight bleed in the corners, especially at the bottom left, which is a bit hard to see in the picture. With local dimming on, the entire screen is more black but there's more blooming around the center cross.

The LG 75NANO90UNA has okay viewing angles. This isn't as good as most IPS TVs, as the image quickly loses brightness when moving off-center. However, you still get a fairly accurate image when viewing from the side so it's a decent choice for a moderately-sized room.

The out-of-the-box color accuracy is decent, but this may vary between units. Most colors are a bit inaccurate and the color temperature is a bit warmer than the 6500K target, giving the image a red/yellow tint. Sadly, white balance is off and gamma also doesn't follow the curve very well, so most scenes are too dark.

The LG 75NANO90UNA has a very good wide color gamut, similar to the LG SM9000 and a bit better than the LG NANO85. It has excellent coverage of the commonly-used DCI P3 color space but it has limited coverage of the wider Rec. 2020 color space. The EOTF follows the curve well until it rolls off at its peak brightness, but most scenes are still a bit over-brightened. The EOTF in 'Game' mode is very similar.

If you find HDR too dim, set the Picture Mode to 'Vivid', Local Dimming to 'High', and both Brightness and Contrast to 'Max'. This results in a noticeably brighter image, as seen in this EOTF.

Update 12/10/2020: We updated the firmware to 03.21.10 and tested the FreeSync support. It works properly and there aren't any issues. We tested it with our Radeon PC, so we couldn't test if 4k VRR goes up to 120Hz.

Update 11/27/2020: We retested the TV with a HDMI 2.1 source.

The LG 75NANO90UNA has a high 120Hz refresh rate. It supports HDMI Forum VRR and FreeSync natively, and it's G-SYNC compatible. It doesn't have any issues with the VRR support at any resolution and there's no screen tearing.

Update 12/10/2020: We updated the firmware to 03.21.10 and measured the VRR input lag.

Update 11/27/2020: We retested the TV with a HDMI 2.1 source. It displays 4k @ 120Hz, but there are some issues. It crashes with VRR enabled when connected to an NVIDIA RTX 3080, but works fine with the Xbox Series X. We couldn't measure the VRR input lag because of the way it kept crashing.

The LG 75NANO90UNA has an excellent low input lag, as long as you're in 'Game' mode. It has an 'Auto Low Latency' mode that detects when a compatible gaming console is connected, and automatically switches to 'Game' mode to ensure the lowest possible input lag. For this to work, turn on Instant Game Response.

If you want to use it as a PC monitor and get the lowest input lag possible, set the input icon to 'PC' and use 'Game' mode.

Update 11/27/2020: We retested the TV with a HDMI 2.1 source. It had issues when connected to our NVIDIA RTX 3080 and couldn't display chroma 4:4:4. We had to keep restarting the TV for it to display 4:4:4, but we consider 4k @ 120Hz @ 4:4:4 unusable because of these problems. However, it didn't have any issues displaying 4k @ 120Hz with our Xbox Series X.

The LG NANO90UNA supports most common resolutions, including 4k @ 120Hz on HDMI inputs 3 and 4. It can display proper chroma 4:4:4 at all resolutions except 4k @ 120Hz, as it doesn't properly display it until we restart the TV and play with the settings. To get chroma 4:4:4, set the input icon to 'PC' from the home dashboard. For full-bandwidth signals, enable HDMI ULTRA HD Deep Color from the settings menu.

This TV supports eARC, allowing it to send high-quality uncompressed audio to a compatible receiver through an HDMI connection. For this to work, go to the Sound Out page in the 'Sound' settings menu, open HDMI ARC, turn eARC on and set Digital Sound to 'Passthrough'. Unfortunately, LG removed DTS decoding from their TVs in 2020.

This TV has decent frequency response. It has a fairly good bass for a TV, but to get the best bass possible, you should get a soundbar with a dedicated subwoofer. It has a fairly well-rounded sound profile, resulting in clear dialogue. It doesn't get extremely loud, so it's not ideal for noisy environments, and there's compression at its max volume.

The distortion performance is decent. The total harmonic distortion is almost inaudible at moderate listening levels but it gets significantly more noticeable when listening at its max volume. However, this depends on the content and not everyone may hear it. If you want a TV with speakers that cause less distortion, check out the Samsung The Sero.

Differences Between Sizes And Variants

We tested the 75 inch LG NANO90 2020 (75NANO90UNA), and for the most part, we expect our results to be valid for the 55 inch (55NANO90UNA), 65 inch (65NANO90UNA), and 86 inch (86NANO90UNA) variants as well. The European variants have different model numbers than the American ones, which are listed below.

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

Compared To Other TVs

Comparison picture

 Top left: Hisense H8G (55H8G). Bottom left: Sony X850G (XBR55X800G). Middle: LG NANO90 2020 (75NANO90UNA). Top right: Samsung Q80T QLED (QN55Q80TFXZC). Bottom right: LG NANO85 (55NANO85UNA).

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.

LG NANO90 2021
55" 65" 75" 86"

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.

Sony X900H
55" 65" 75" 85"

The Sony X900H is better overall than the LG NANO90 2020. The Sony has a VA panel, producing much deeper blacks, and it has a better full-array local dimming feature. It also gets brighter, has more accurate colors, and it has a more uniform screen. However, the LG has wider viewing angles due to its IPS panel, so it may be preferable if you have a wide seating arrangement.

LG NANO85
49" 55" 65" 75"

The LG NANO90 2020 is better than the LG NANO85. Being a higher-end model, the NANO90 has some more features, like full-array local dimming.

The Samsung has a VA panel and a full-array local dimming feature that allow it to produce deep blacks. It also gets brighter and has better out-of-the-box color accuracy. Even though the LG has an IPS panel, the viewing angles are better on the Samsung because of its 'Ultra Viewing Angle' technology.

LG CX OLED
48" 55" 65" 77"

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.

Samsung Q80/Q80A QLED
55" 65" 75" 85"

The Samsung Q80/Q80A QLED and the LG NANO90 2020 are good TVs with similar panel types. The Samsung has an ADS panel, while the LG has an IPS; they each behave similarly with wide viewing angles and a low contrast ratio. The Samsung gets significantly brighter, making it a better choice for well-lit rooms or watching HDR content.

Overall, both TVs are very similar but the NANO90 has a better contrast ratio, better out-of-the-box color accuracy, a quicker response time, and the speakers are better. The SM9000 comes with a nicer-looking stand, it gets a bit brighter, and it has wider viewing angles.

Hisense H8G
50" 55" 65" 75"

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 gets much brighter, has much improved out-of-the-box color accuracy, and it supports HDMI 2.1 on all four HDMI inputs. On the other hand, the NANO90 has a quicker response time and it has better uniformity.

LG GX OLED
55" 65" 77"

The LG GX OLED is much better than the LG NANO90 2020, but they use different panel types. The GX's OLED panel can turn off individual pixels, resulting in an infinite contrast ratio and perfect black uniformity. It also has much wider viewing angles and has a near-instant response time. On the other hand, the NANO90's LED panel appears to be immune from permanent burn-in, unlike the GX.
