In mid-2020, the LG Nano 90 Series went up for sale and comes in four sizes: 55-inch, 65-inch, 75-inch and 86-inch. What we are examining here is the 65-inch LG (65NANO906), or the American LG 65NANO90.

Design

The LG Nano 90(65NANO906) is a bit … normal compared with some of the ultra-slim, gleamingly metallic LCD TVs that LG has produced over the years. Its dark frame is thin, but it does nothing to conceal how much plastic it holds, whilst its back sticks by conventional TV standards to miles away.

However, given that it accommodates a direct LED lighting system, where the LEDs are placed directly behind the screen, we are more than happy to cut it some slack for its rump. This kind of lighting always provides better contrast than the edge lighting, and is particularly important for IPS TVs such as the LG Nano 90 (65NANO906).

The TV may be put on a pair of basic-looking feet, but if it’s hung on your wall, it looks even more prettier. Given its very deep back.

Connections for a Mid-Range TV are strong. Of the four HDMI s that have been given, two can accommodate enough data bandwidth to support the 4 K, 120Hz, HDR 4:4:4 10-bit images that we hope will become useful later this year when the PS5 and Xbox Series X launch. Three USBs and a digital audio output are joined to these.

Smart TV (webOS)

The LG Nano 90 (65NANO906) uses the platform of LG’s own webOS. This hasn’t significantly improved from the 2019 edition. The only new things to note are a sports feature that lets you track your favorite sports teams’ results and live matches; the option to customize webOS notifications gives you; a better designed ‘Home Dashboard’ for tracking and controlling all of your connected and networked devices; and enhanced search and recommendation systems.
The biggest and most surprising change in webOS is, in fact, something the LG Nano 90  (65NANO906) has lost: the catch-up apps for the major terrestrial broadcasters in Britain.

However, WebOS continues to be one of the easiest to use, most customizable and most economical smart platforms around (in terms of the screen real estate it uses). And apart from the missing land-based broadcaster catch-up apps, it supports all the key streaming platforms you ‘d expect it to be. Disney Plus included, and Apple TV Plus.

HD/SDR Performance

At this stage we will address in more detail the main image features of the LG Nano 90 (65NANO906): First, its direct LED lighting scheme is assisted by local dimming. That only supports 32 independently operated zones; hardly a bounty. Combined with a new power management system that diverts power from dark parts of the picture that don’t need it to bright areas that do, however, those 32 zones are proving to be unforeseenly effective. They do have to contend with an IPS screen, though.

The LG Nano 90 (65NANO906) carries a processor of the LG Alpha 7 Generation 3. This isn’t as good as the Alpha 9 processor found in most of LG’s 2020 OLED TVs-particularly when it comes to colour. Yet the Nanocell device is in itself strong enough to provide very efficient SDR light.

4K/HDR Performance

Here we have HDR pictures that look brilliant (actually brighter than the calculated peak light intensity of around 520 nits), but can also usually reach deep black rates decently. Even more unexpectedly, the LG Nano 90 (65NANO906) can display bright-on-dark HDR highlights, such as the moon in a night sky,  without having to excessively dim the bright highlight down or creating a large, bold distracting grey cloud around it.
In this latter sense the (65NANO906) is in particular a surprise relative to previous IPS displays.

The extra spectrum of light, contrast and colour associated with HDR sources also gets even more benefit from LG‘s Nanocell technology, helping to produce lots of vibrational colour without losing some of the amazing subtlety that stood out so much when watching SDR.

Native 4 K videos look smooth and precise-and LG ‘s new choice for Cinema Clear motion means that clarity rates stay high even though there’s a lot of action in a 24p video. Even if you turn off the motion processing, on previous LG LCD generations the movement clarity of the TV with 24p movie sources appears more natural than it was in its ‘native’ state.

Sound

The LG Nano 90 (65NANO906) sounds pretty good provided you use LG’s AI Sound setting. The idea behind AI Sound is to combine the LG’s own virtual surround sound processor with the kind of close understanding of a TV speaker ‘s capabilities that you only get from the people who actually built it. The result is a substantial scale and dynamic soundstage that has far more room-filling, forward-throwing impact than you hear on most TVs.

Voices are well rounded and locked into the screen, and the speakers can go noisy without being harsh or blurred.

Note that, surprisingly, when listening to Dolby Atmos soundtracks the AI Sound option has more dynamism and range than the default Dolby Atmos mode.

Conclusion

The (65NANO906) is by far the best LG ever LCD TV. It finally finds a way to improve the LG’s long-running LCD contrast and backlight problems massively-if not completely solved. It also does this without sacrificing the viewing angle advantages of IPS LCD screens, while at the same time bringing out the strengths of LG’s Nanocell color technology in a way that we have never before been able to see.
