My take on LG NANO90


The LG NANO90 is a mid-range IPS smart TV that offers good picture quality thanks to its 4K UHD NanoCell display. Also, this television has wide viewing angles and excellent motion-handling performance. However, the TV has a poor contrast ratio.

  • Wide viewing angles
  • Satisfactory port selection


  • Mediocre contrast ratio

LG NANO90: At First Glance

For a while now, LG has been one of the world’s leading brands in the television market. This is because they manufacture televisions that offer exceptional performance and features.

One of these televisions is the LG NANO90 which was released in 2020 and is the main focus of this review article. To give more details, this television is a smart 4K UHD television with good picture quality and wide viewing angles.

Also, the television comes with WebOS, as with most LG smart televisions. However, the LG NANO90 has a few disappointing drawbacks, such as a poor contrast ratio.

Having mentioned a few things about this television, don’t you wish to know more? To find out more about the LG NANO90, read on!

LG NANO90: Design, Dimension, and Weight

The design of the LG NANO90 is good and pretty typical of most LG televisions. From the front view, the TV’s 55-inch display is bordered by slim bezels, which gives it a modern look.

However, the bottom bezel is a little bit wider than the others. This is due to the fact that it accommodates an “LG NanoCell” inscription on the right side.

That being said, the LG NANO90 comes with two legs. These legs are composed of plastic with a glossy-black finish.

Even though these legs are made of plastic, they are sturdy and prevent the television from wobbling too much when nudged. However, the legs are positioned very close to the edges of the television.

As a result, you will need a fairly large tabletop to place the television on if not mounted on the wall. On a positive note, the legs feature clips at their backs, which serve as a form of a cable management system.

Turning over to the back, the LG NANO90 has a metallic back panel with a simple design and black finish. Furthermore, you will find 600 x 400 VESA mount holes on this back panel for wall-mounting the television.

Gladly, the back panel of the television isn’t particularly chunky. Therefore, when wall-mounted, the TV shouldn’t stick out of the wall or look awkward.

For the dimension and weight, the LG NANO90 measures 1236.9 x 71.1 x 716.2 mm (W x D x H) and weighs 17281.8 g. Comparatively, this television is slimmer but heavier than the Hisense 55R6G.

To be precise, the Hisense 55R6G measures 1231.9 x 73.6 x 711.2 mm (W x D x H) and has a weight of 11294.4 g.

In conclusion, the LG NANO90 features a modern design with thin bezels and a cable management system. However, this television is heavier than most of its competitors.

Thus, I will rate the LG NANO90 an eight out of ten in this design section.

LG NANO90: Display Features and Picture Quality

To begin with, the LG NANO90 comes with a 55-inch LCD NanoCell display. Furthermore, the display features a 4K UHD (3840 x 2160) resolution.

Combined with the NanoCell technology, this 4K UHD resolution allows the television’s display to render colorful and realistic picture quality. In addition to the 4K UHD resolution, the LG NANO90’s display is made with an IPS panel.

Thanks to this IPS (In-Plane Switching) panel, the display offers wide viewing angles. As a result, the display won’t lose picture quality when watched from the sides or off-center.

However, as with most IPS panel displays, the LG NANO90’s display has a poor contrast ratio – it features a contrast ratio of 1068:1. The contrast ratio is the ratio between the brightest whites and the darkest black that a TV display can produce.

Additionally, a high contrast ratio (3000:1 or higher) means the display will be able to render deep blacks. Technically, the higher the contrast ratio, the deeper the blacks the display produces.

Sadly, with a contrast ratio as low as 1068:1, the LG NANO90’s display won’t be able to produce deep blacks. Practically, the blacks that the display renders tend to look more like gray.

Due to that, movies with plenty of dark scenes might not be fun to watch on the LG NANO90. On the bright side, the television’s display supports local dimming, which kind of compensates for its poor contrast ratio.

This is because local dimming is a feature that enhances the black level of a display by dimming the backlight zones. Therefore, thanks to this feature, the LG NANO90’s display will be able to render deeper blacks than it should without the feature.

Therefore, improving the dark room performance and overall picture quality of the television.

Moving on, the LG NANO90 has good reflection handling. This is due to the semi-gloss coating on its display screen that reduces the intensity of light reflected on the display.

That being said, the LG NANO90 offers an average display brightness. To be precise, the television’s display recorded a maximum brightness of 409 nits.

Although this brightness is enough for moderately-lit rooms, it will struggle to keep up in well-lit environments or outdoors.

As expected from a 2020 television, the LG NANO90 supports HDR (High Dynamic Range). Specifically, it is compatible with some HDR effects like Cinema HDR (Dolby Vision, HDR10, HLG), Dolby Vision IQ, and HDR Dynamic Tone Mapping.

HDR (High Dynamic Range) is a display technology that improves the brightness and color accuracy of a display. Therefore, when rendering HDR-supported content, the picture quality of the LG NANO90 will be realistic and life-like.

For those who don’t know, HDR-support content can be found on streaming apps like HBO and Hulu. Apart from the HDR, the LG NANO90 also offers some picture technologies, such as the α7 Gen 3 Processor 4K.

The α7 Gen 3 Processor 4K is an intelligent picture processor that analyzes and optimizes images. Thereby allowing the display to produce smoother and clearer images.

In addition to the α7 Gen 3 Processor 4K, the LG NANO90 also comes with a 4K upscaler technology. With the help of this technology, the television’s display will be able to render HD or SD content in near-4K quality.

That aside, the LG NANO90’s display offers a good response time of 10.1 milliseconds. The response time is the time it takes a display to change from one color to the other.

Hence, thanks to its good response time, there should be fewer blur trails when the LG NANO90 is rendering fast-moving content. Besides, this television’s display also features a decent input lag of 12.5 milliseconds.

As a result, the television is ideal for casual gaming. For your information, input lag is how fast it takes a TV display to respond to signal transmissions from external devices.

All things considered, the LG NANO90 deserves a rating of eight out of ten in this display review section.

LG NANO90: Sound Features

For sound production, the LG NANO90 comes with 2.0 CH 20-watt down-firing speakers. These speakers produce decent sound quality and are moderately loud.

However, they are not loud enough to fill an enormous room with sound. Nonetheless, the speakers are able to produce fairly decent bass even though the television lacks a built-in subwoofer.

Regardless, you can purchase a soundbar alongside the television to get a much better bass production.

Moving on, the LG NANO90’s speakers offer clear dialogue. Dialogue refers to the conversation between multiple individuals in a TV show or movie.

Hence, due to its speakers’ clear dialogue production, the LG NANO90 is ideal for watching conversation-driven content. Besides, this television comes with Dolby Atmos and Ultra Surround sound technologies.

Thanks to these sound technologies, the speakers are able to deliver an immersive and theatre-like sound quality. In terms of sound distortion, the LG NANO90 is brilliant.

To be more specific, the television’s speakers produce minimal distortion, even at the maximum volume level. Distortion in this situation is the alteration of sound signals, thereby enabling a sound device to produce unwanted noises.

Having said all that, I will rate the LG NANO90 an eight out of ten in this sound features review section.

LG NANO90: Ports and Connectivity Features

The LG NANO90 is outfitted with a good number of ports that are all located in a compartment on the left side of its back panel. Moreover, the ports are divided into two sections – some are facing the left while the others are down-facing.

These ports include three USB ports and four HDMI ports. That’s not all; there is also an optical audio out, an RF port for antenna connection, and a composite AV port.

In addition to that, the LG NANO90 also comes with an Ethernet port. Meanwhile, for wireless connectivity, the television offers built-in 802.11ac Wi-Fi and Bluetooth 5.0.

Moving on, the LG NANO90 comes with LG’s magic remote control. This remote is averagely sized and composed of plastic material with a black finish and curved edges.

Furthermore, the magic remote contains several functional buttons. For example, the remote control features a full number pad, a volume rocker, and a channel rocker.

The remote also has a round-shaped navigation button with a scroll wheel in the center. There are also special buttons for quick access to Netflix and Amazon Prime Video on the remote control.

Moreover, the magic remote control has an in-built microphone for voice input with Amazon Alexa or Google Assistant.

In summary, the LG NANO90 offers sufficient ports and a voice-enabled magic remote control. Hence, I will be rating this TV a nine out of ten in this review section.

LG NANO90: Smart Features

Like most LG smart televisions, the LG NANO90 uses WebOS as its smart operating system. The interface of this operating system is smooth and responds to input swiftly.

In addition to that, WebOS has a wide selection of pre-installed applications and streaming services. These include Sling TV, YouTube, Hulu, Disney+, Netflix, and Amazon Prime Video.

To make things better, the WebOS comes with a built-in app store called the LG Content Store. With the help of this app store, you can download additional applications on the operating system.

However, the LG Content Store doesn’t have as many applications as the Google Play Store or Samsung Store. Nonetheless, the television is cast-enabled, meaning you can cast/mirror content from your smartphone to the television.

In addition to that, the LG NANO90 supports Apple’s HomeKit and AirPlay. As a result, you can share content from your Apple devices to the television.

Sadly, WebOS features ads on its home screen and app store, and you cannot disable them.

Regardless, I believe the LG NANO90 deserves a nine out of ten rating in this smart features review section.
