4K TV review LG Nano90: great for big rooms [análise/vídeo]

For those who are afraid of OLED, the most complete 4K TV from LG in Brazil in the new generation is the Nano90. It only arrived in the country in giant sizes, 75 and 86 inches, bringing exclusive features within the brand’s liquid crystal television line, such as complete local dimming by zones and Direct LED lighting, to offer deeper blacks to a more demanding audience .

With launch prices between R $ 15,000 and R $ 27,000, the Nano90 is a representative of LG in the premium segment and is far from cheap, but it can be an opportunity to put a bigger screen indoors while spending less money than in an OLED model. Is it worth it? I tested the Nano90 in the past few weeks and count my impressions in this review.

Design, connections and remote control

The smallest Nano90 available in Brazil was the largest TV I have ever tested on Tecnoblog. This is also the first TV review I had to shoot with an ultrawide camera. And the design is consistent with the weight of 35 kg of the 75-inch version, with two metal feet in an inverted “V” shape, at the ends of the screen, which leave the equipment firm on a piece of furniture. If you have very strong and caring people to help, you can install the Nano90 in a large wall mount.

The look of the Nano90 is unobtrusive, with a thin border around the screen, an LG NanoCell inscription hidden in the lower right corner and a metal back without any texture or fabrication. The gap between the two support feet is large enough to even install some models of soundbar: an LG SK9Y, for example, which is the width of a 55-inch TV and just under 6 centimeters in height, fits perfectly down there .

The connections are concentrated on the left side and include three USB ports, an Ethernet input, an optical audio output and four HDMI inputs, half in version 2.0 and half in 2.1, prepared for the new generation of consoles, with games in 4K at 120 Hz. LG did not include four HDMI 2.1 ports as in OLED TVs, but it gains points in relation to the competition: Samsung, even in premium TVs like the Q80T, has only brought an HDMI input in the new standard.

The Smart Magic remote control has become standard on LG’s new line of TVs and also comes with the Nano90. It has many buttons, is not so compact and requires initial motor coordination training to navigate the elements of the screen with a mouse in the air. A button allows you to quickly open Netflix, while the Amazon Prime Video shortcut has a dual function and can also trigger Alexa.

Image quality

In terms of image, the Nano90 is LG’s last step before OLED TVs. In 2020, the company even launched the Nano95 and Nano96 models in Brazil, which bring superior panels, but they fall into another category because they are 8K. Among 4K, the Nano90 is the only one with full-array local dimming, a feature that I consider indispensable in a premium LCD model; Nano86, immediately below, no longer has the feature.

Analyzing the image quality of the Nano90 is complex, because it will never be unanimous. The “Nano” of the Nano90, which is ironic in such a big TV, is related to the LG NanoCell technology, which uses nanoparticles to filter colors, in a process similar to QLED models. But the difference from rivals is the use of an IPS panel, to offer a wider viewing angle, in contrast to Samsung and TCL, which tend to prefer VA-type screens.

Particularly, I don’t like IPS screens so much because of the lower contrast and the greater possibility of black inconsistency, which is really notable on the Nano90. LG’s premium model has good image quality and is superior to the brand’s simplest TVs, such as the UN8000, but the inferiority compared to Samsung Q80T, the main competitor in the price range, is noticeable in these points.

The Nano90 has a satisfactory brightness, but struggles a little more than its rivals to cope with very bright environments, with natural light falling on the panel. In this case, what plays against the LG model is that the contrast is not so good, with an ok white and a grayish black. This also impairs the display of HDR content, which is not as dynamic in dynamic range even with Dolby Vision films and series.

The local full-array dimming pleased me and stayed within expectations. In the standard configurations, LG does well for not being too aggressive, whether trying to offer deep black at all costs and hiding objects, or creating hard clouds around areas of high contrast, as it happens in several premium models from Samsung. I can see traces in zone transitions, indicating that they could be faster, but this is not bad in real content.

The viewing angle, as expected from an IPS screen, is very good, with no significant variations in color or brightness even sitting at 45 degrees, which is great news for those with larger living rooms. For those who play, the input lag is always below 15 milliseconds, which is an excellent brand and complements the strength of the two HDMI 2.1 ports, ready to receive an Xbox Series X in one and a PlayStation 5 in the other. Or at least dream about it.

Sound quality

The sound that comes out of the Nano90’s built-in speakers is good for reaching high volumes without distorting, being able to fill larger environments without much difficulty. As with most TVs, the mediums are clear and favor dialogue. Of course, you won’t hear the last drop of definition on an integrated TV speaker, but many people won’t feel the need for a soundbar.

What impressed me was the bass. Again, we are not talking about something at the level of a dedicated subwoofer system, but an integrated sound. And the Nano90 is able to put the tip of the foot at lower frequencies, starting to generate that good feeling of the sub-bass beats. LG has done a good job on the speakers on premium TVs, like the OLED CX, and has not left its best NanoCell 4K behind.

Smart TV software and functions

Inside, Nano90 runs the webOS 5.2 operating system, which stands out for its colorful screens full of animations to highlight the fluidity of the interface and the excellent offer of applications. In the LG content store, you can find Netflix, Amazon Prime Video, Disney +, YouTube, Apple TV +, Spotify, Google Play Movies, Vivo Play, Globoplay, Globo Channels, Telecine Play, Plex, HBO Go and more.

The default personal assistant is Google Assistant, which responds quickly but needs to be triggered manually by the microphone button, since the hands-free feature has been restricted to LG’s ultra-thin models in this generation. The shortcut to Amazon Prime Video on the remote can turn into a button for Alexa with a long press.

As with other LG TVs in 2020, you have access to the Control Panel, which allows you to control compatible smart home devices. You can also activate the Sound Sharing feature, which turns the Nano90’s speakers into a kind of Bluetooth speaker; and mirror smartphone content with Miracast or Apple AirPlay.

Worth it?

LG offers a very complete package on the Nano90, with HDMI 2.1 ports, good quality integrated speakers, an operating system with an excellent offer of convincing applications and technologies, such as Dolby Vision and 120 Hz panel. But I would have liked to see a greater boldness of LG in this model, since we are talking about the best 4K LCD TV of the brand in 2020, behind only OLED models.

The image is good for those who are afraid of OLED, but it is not the best you could get with an LCD panel. In the same price range, the competitor of the Nano90 is the Samsung Q80T, available up to the size of 75 inches. The fellow QLED slips in some places, as in the lack of Dolby Vision and in the economy in the connections, but it delivers a stronger brightness and, after some adjustments, a remarkably higher contrast, with deeper blacks than LG.

I can no longer see such a huge advantage in the great viewing angle of LG’s IPS because Samsung and Sony are already managing to cope well with this limitation on their VA screens. So, the only point where I see the Nano90 stand out is the cost-benefit in giant sizes: this is one of the few premium models on the Brazilian market that can be purchased in an 86-inch version.

The 86-inch Nano90 can be found in Brazil for around R $ 25,000 in retail at the time of publication of this review. It is obviously a high value, but it is already lower than the 77-inch LG CX, which has superior image quality, but smaller size. If what you’re looking for is an inch, the Nano90 can be an interesting purchase option for large environments.
