The LG NANO90 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. Although this TV 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. It has an impressive response time, extremely low input lag, and a 120Hz refresh rate, great for gaming.
Currently, it doesn't support FreeSync variable refresh rate (VRR) technology, but this should be available in a future firmware update, so we'll update the review once it comes out.
The LG NANO90 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 has a low contrast ratio and mediocre black uniformity, so it's not a good choice for watching movies or gaming in the dark. This TV isn't able to display true HDR content either because it doesn't get bright enough to bring out highlights. It also has a quick response time and really low input lag, great for gaming.
The LG NANO90 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's able to remove judder from any source.
Good for watching TV shows. The LG NANO90 doesn't get very bright, but luckily, it has impressive reflection handling so you shouldn't have any issues placing this in a bright room. It also has fairly wide viewing angles if you want to watch shows with the entire family. The TV upscales lower-resolution content, such as from cable boxes or apps, well and without any issues, and LG's app store has a great selection of apps available for download.
The LG NANO90 is very good for watching sports. It has fairly wide viewing angles, and its impressive reflection handling makes the TV suitable for bright rooms. Sadly, there's some dirty screen effect visible in the center, which could be distracting when watching sports. On the upside, it has a great response time and a black frame insertion feature to help improve the appearance of motion.
The LG NANO90 is impressive for video games. It has an impressive 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. Currently, it doesn't support any VRR, but that should come in a future firmware update.
Okay for HDR movies. The LG NANO90 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.
Very good for HDR gaming, mainly due to its impressive gaming performance. The NANO90 has a very low input lag and its really quick response time results in minimal motion blur. It currently doesn't support VRR, but that will come in a future firmware update. Sadly, HDR content doesn't look good on this TV because it doesn't get bright enough to bring out highlights.
The LG NANO90 is great to use as a PC monitor. It has fairly wide viewing angles and impressive reflection handling. It displays proper chroma 4:4:4, which is important for reading text, and it has a really low input lag. Fast-moving content also looks good thanks to its quick response time, and this TV has no risk of permanent burn-in.
The LG NANO90 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 in the United States and the LG NANO86 in Canada and Europe. In the United States, it sits below the LG NANO91, which appears to be a similar TV with a different stand. Above the 9 Series is LG's 8k Series. Its main competitors are the Sony X800H, Samsung Q70T QLED, and the Hisense H8G.
The NANO 9 Series 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.
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".
The back is made out of smooth plastic 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 NANO 9 Series is fairly thin and if you wall-mount it, it won't stick out much, if at all.
This TV has a decent build quality. It's mainly made out of plastic that feels cheap and there's nothing premium about it. Still, the plastic is solid and it holds the TV together well. There's not a lot of wobble, especially for a TV of this size. Lastly, the plastic near the inputs flexes a bit, but this shouldn't be an issue for most people.
The contrast ratio isn't bad for an IPS panel TV. 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.
The NANO 9 Series 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. The local dimming also crushes dark scenes. 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. 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.
The NANO90 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).
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.
Unremarkable peak brightness in HDR. Once again, the 9 Series 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.
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.
Just okay gray uniformity. 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 NANO 9 Series has decent viewing angles. This isn't as good as most IPS TVs, but you still get a fairly accurate image when viewing from the side.
Mediocre black uniformity. Without the local dimming on, 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. The backlight bleed is noticeable when you watch dark scenes in a dark room. With local dimming on, the entire screen is more black but there's more blooming around the center cross.
Impressive reflection handling. It performs well in moderately-lit rooms, and even with direct light on it, the reflections don't get too distracting. You shouldn't have any problems placing the NANO 9 Series in a bright room.
Okay out-of-the-box color accuracy. 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, which affects the shades of gray. Gamma also doesn't follow the curve very well, so most scenes are too dark.
After calibration, the NANO 9 Series has outstanding color accuracy. Any remaining inaccuracies aren't visible without the aid of a colorimeter. The gamma also follows the curve almost perfectly. Sadly, the color temperature is a bit too cold, giving the image a blueish tint.

480p content, such as from DVDs or old video game consoles, is upscaled without any issues.
This TV upscales 720p content, like from cable boxes, well without any artifacts.
The NANO 9 Series 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 noticeable brighter image, as seen in this EOTF.
Alright color volume for the NANO 9 Series. Due to the low contrast ratio, it can't display dark colors well and like most LED TVs, it can't display bright blues.
Decent gradient handling, but sadly, not as good as the LG SM9000. There's noticeable banding in red and even more so in gray. Enabling the Smooth Gradiation doesn't affect the test pattern but it makes real content look better.
There's some very minor temporary image retention immediately after display our high-contrast static image for 10 minutes. This could vary between units and it has nothing to do with the permanent burn-in associated with long-term exposure to static images.
While some IPS panels like this have some temporary image retention, this doesn't seem to be permanent as the IPS panel in our long-term test appears to be immune.
The NANO 9 Series has an impressive response time. There's some overshoot in the darker transitions, but overall, motion looks smooth. This is a significant improvement over the LG SM9000.
The NANO90 is flicker-free only when the backlight is at 100% brightness. Otherwise, it flickers at 960Hz, which is so high that it shouldn't be noticeable for most people. The backlight flickers at 120Hz when TruMotion is enabled and at 60Hz with the black frame insertion feature enabled.
The NANO90 has a black frame insertion to help improve the appearance of motion. It flickers at 120Hz with TruMotion enabled in 'Game' mode, and it flickers at 60Hz, with the Motion Pro setting enabled. The BFI feature doesn't actually doesn't clear up motion blur as much as other TVs.

This TV can interpolate motion up to 120fps, known as the 'Soap Opera Effect'. To turn it on, set De-Judder and De-Blur to 'Max' in the TruMotion settings. It does an okay overall job with motion but in action-packed scenes, there are some artifacts. However, it's not very distracting and shouldn't be noticeable with most content.
Since the NANO90 has such a fast response time, there's some stutter as each frame is held on longer. You can reduce the amount of stutter by enabling the motion interpolation feature.
The TV can remove judder from any source, such as Blu-ray players or native apps. To remove judder, turn on Real Cinema.

The NANO90 has a high 120Hz refresh rate. Currently, it supports HDMI Forum VRR and it's also supposed to support FreeSync in a future firmware update, so we'll update the review once it comes out and we're able to test it.
The NANO 9 Series 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.
This TV supports most common resolutions, including 4k @ 120Hz on HDMI inputs 3 and 4. It's able to display proper chroma 4:4:4 at all resolutions except 4k @ 120Hz, which is important for reading text if you're using this TV as a PC monitor. To get chroma 4:4:4, set the input icon to 'PC' from the home dashboard. For full bandwidth, enable HDMI ULTRA HD Deep Color from the settings menu.
The NANO90 supports 4k @ 120Hz on HDMI 3 and 4, but since we don't have a HDMI 2.1 source yet, we can't test the full bandwidth just yet. We'll update the review once we do.
