How to buy the best LG TV

LG's TV line-up consists of numerous OLED ranges – bolstered by LCD and NanoCell 4K sets. We explore the new technology in these LG TVs, so you know how the ranges differ and what to spend

LG C1 OLED

LG is one of the leading TV brands and is best known for its OLED TVs that forgo backlights in favour of self-illuminating pixels.

It also makes Nanocell and LCD sets. Most are 4K, but LG makes some 8K sets, too. It debuts its high-end TVs at the annual Consumer Electronics Show (CES) each year and releases most of its yearly line-up in the spring. 

We've broken down each range in LG's line-up and explained the tech that powers them. You can use our guide to find out which tech is worth paying extra for, and which is right for your budget.

LG's 2022 TV range overview

We'll update this page throughout 2022 as soon as we get more information on LG's ranges and when we have full tests of LG's 2022 TVs.


Want to find out more about LG's 2021 range? Whether you've browsing the shops or considering buying second-hand, make sure you take a look at our round-up of LG's 2021 TV range.


LG OLED evo G2 Gallery Series

LG OLED evo G2 4K OLED

The G2 range is likely to be LG's most high-end series of OLEDs outside some 8K models. It has released Signature range OLEDs in the past, some of which roll out of the base like wallpaper, but these are typically huge and astonishingly pricey. 

The G2s are the most high-end models that most people might actually consider buying. They are designed to be wall mounted and come with the mount to do it, rather than a traditional stand. 

The big change for 2022 is the new ‘brightness booster’. This is something OLED evo technology was supposed to do - but in our tests of the 2021 G ranges, we didn’t notice an increase in Nits (the measurement for screen brightness) over LG OLEDs without the added evo bit. We didn’t exactly think those OLEDs weren’t bright enough, though. 

The G2s have the A9 Gen 5 processor and you’ll be able to buy an enormous 97-inch model (LG’s biggest OLED); probably worth mounting that onto a supporting wall, we reckon. There's also a 55, 65 and 77-inch model to choose from.

LG OLED C2 range

LG OLED evo C2 42-inch 4K TV

The C range OLEDs are LG's most popular and widely available. We don't see that changing in 2022 as LG is releasing a 42-inch model. It's the first time we've seen one so small. This means anyone who is short on space but after high-end TV tech will finally have an option.

Like the G2 range, the C2s will use the Alpha 9 fifth generation processor. But they are more conventional and come with a table stand - though they can still be wall mounted.

The LG C2s also support the brightness booster and OLED evo technology, so they should have the edge over 2021 versions. Or, at least when it comes to displaying a brighter image.

As well as the 42-inch model, you'll be able to buy  48, 55, 65, 77 and 83-inch versions.

LG TV technology explained

There's no shortage of intriguing technology in LG's TVs, including an improved image processor, new HDR formats and object-based sound rendering.

Alpha 9 processor

LG's high-end TVs for 2022 are powered by the fifth-generation of the Alpha 9 processor, while lower-end OLEDs and LCDs will likely retain the fourth-generation Alpha 9. The latest version builds on its predecessors with several added features, most notably the ability to recognise and enhance faces and bodies as well as creating a better sense of depth from foreground and background images. 

TVs with this upgraded chip will analyse every frame of what you're watching and hone it to look as close to 4K or 8K as possible. What resolution the content is boosted to will depend on your TV. 8K sets rely on this sort of technology as there's very little 8K content to watch, but if it works well then SD and HD footage will look better than ever on 4K TVs, too.

The latest processor should help sound, too. It will enable the TV speakers to simulate 7.1.2 surround sound: that’s three speakers in front, four behind, one subwoofer for bass and two speakers sending sound over your head. We’ll definitely be testing those surround sound capabilities, to see if the Gen 5 can really do all that simulation.

Dolby Atmos and DTS Audio

The sound-processing tech in LG's OLEDs should help to create a more immersive sound experience. It does this by creating object-based sound effects, which should make it seem as though the TV audio is all around you rather than coming directly from the TV. 

In theory, this means that the sound of a plane taking off on screen would seem to come from above you, or the sound of a tumultuous crowd in a stadium would surround you.

Dolby Vision IQ

HDR is designed to improve the contrast of whatever you're watching, but we sometimes think it makes things worse. Our most common complaint is how the deeper blacks and brighter whites can obscure detail. As HDR normally goes hand in hand with 4K, it's a crime to cover up the extra detail the high resolution of 4K affords.

Dolby Vision IQ offers a solution by using the light sensors in the TV to adjust contrast based on your room's ambient light. Our tests of LG's high-end 2021 TVs will reveal how well this works, but it's a good solution in theory.

Filmmaker mode

It's strange to think that when you watch a film on your TV, it may not look the way the people who made it intended. That's why the likes of Martin Scorsese, Ava DuVernay and Rian Johnson put their weight behind Filmmaker Mode, which disables TV-added effects that can compromise that original vision.

It should make for a more cinematic experience, as motion-smoothing effects are blocked. In our tests we tinker with picture settings to get the best picture from each TV, and motion smoothing is something we often turn off ourselves. For anyone who doesn't want to delve into the deep recesses of TV picture settings, the Filmmaker Mode should be a welcome addition to LG's high-end TVs.  

Gaming features

Refresh rate and input lag are vital to enjoying video games on modern TVs. Refresh rates refer to how often the image on the screen refreshes. If you watch a film, you usually get 24 frames per second, which sounds like a lot, but many video games rattle through 60 frames per second or even 120.

If the refresh rate of a TV can't cope, then games begin to look jagged and are less pleasant to play. LG has worked with graphics card manufacturer Nvidia to improve the refresh rates on its TVs. High-end LG TVs now support up to 120 frames per second.

They have worked together on input lag, too, which is how quickly the display responds to button presses on a game controller. A small delay can mean the difference between making a jump and falling short, and it's something gamers won't put up with. LG's TVs should provide a better experience for gamers with all this extra tech.

HDR10, Dolby Vision and HLG HDR formats

LG is covering most of the HDR (high dynamic range) bases with its TVs. The OLED models have three formats built in (as well as Dolby Vision IQ we mentioned earlier) so there won't be many devices or HDR content that they won't be compatible with.

HDR10 is the standard format at the moment, although Samsung and Panasonic's support for HDR10+ may change that.

HLG is the type of HDR that broadcasters will use when they launch HDR channels. It's not so useful now, but given that most of us keep the same TV for years, it's good to know that it will work with new channels. 

Unlike HDR10, Dolby Vision costs the manufacturer a licence fee to use. Cost aside, the key difference between it and HDR10 is metadata – this is the data that makes up the quality of the picture. HDR10 gets one dump of information for every film and TV show compatible with HDR; this means the HDR version of what you're watching will be the same regardless of the TV it's being displayed on. 

Dolby Vision, on the other hand, can react to what's on screen by accounting for the brightness, colour and contrast of different TVs.

If you're unsure what this technology does, then head to our guide on what is HDR TV?
TV

HFR (high frame rate)

HFR ups the number of frames a TV can display per second to 120. This should make high-speed action look silky smooth, with no hint of blur.

This is a feature that comes part and parcel with HDMI 2.1 connections (yes, even your TV's connections get updates) which is something many LG TVs support. HDMI is a type of connection you'll find on your TV that enables you to link it up with other devices, such as games consoles.

Gaming is the natural fit for this technology. It's unlikely to be used for TV or movies, which are displayed at around 24 frames per second. Upping this to 120 would look very unnatural.

OLED evo

OLED evo is supposedly an improvement on regular OLED technology, and it seems the big shift from standard OLED sets to OLED evo ones relates to brightness. It makes sense since this is one of the few ways OLED displays lag behind backlit LCD and QLED ones. 

We don't know how much brighter they will be yet, but our tests determine peak brightness of every TV, so we'll know how they compare to standard OLED models. OLEDs are famed for their peerless black levels and if the evo technology can push the lighter parts of the screen even further it should increase the range and make those darker points look even more impressive.

The OLED evo tech can be found in the G2 and C2 ranges in 2022.

QNED Mini LEDs

TVs get bigger and bigger, but manufacturers try to make some aspects smaller. The LEDs that make up the backlights in most TVs shine onto a colour producing layer to create a picture. Generally, the more bulbs make up the backlight the more control the TV has over contrast, brightness and what portions of the screen are lit.

LG's Mini LEDs are its smallest ever and it means close to 30,000 bulbs can be packed behind a display. This creates numerous, independently controlled dimming zones for impressive contrast control.

It's unlikely to match the self-lit pixel glory of OLEDs, but it could come close and the screen will probably be brighter than OLEDs can manage.

Nanocell

LG TVs with 'NANO' in the model name are Nanocell TVs. They are basically LCD TVs, so use a backlight, but have an extra layer of nanocells, which are designed to boost colour. Nanocell models range from mid to high-end.

ThinQ

TVs get smarter every year, and the ThinQ technology that debuted in 2018 is still favoured in LG's 2022 TVs. ThinQ-enabled TVs will be able to control other LG appliances, so your TV can alert you when your washing is done, or it might display the contents of your fridge. 

Voice search will still feature, and you'll be able to search for specific channels and apps, or look up films of a certain genre or starring a specific actor. If you have an Amazon Echo or Google Home, you can use those to control your TV rather than the remote.

LG's 2021 TV range overview

Some of LG's 2021 TVs blew our socks off and should still be available well into 2022. They will start to go out of stock as the new ranges replace them, but while they are still around they are worth considering.

Scroll down for more detailed information about LG's 2021 range.

LG OLED evo G1 Gallery Series

LG OLED EVO G1

2021 was the first time we saw LG's OLED evo technology, but only one range got it: the Gallery Series G1. 

Models in this range are designed to look like works of art, with a range of paintings and pictures that can be displayed while the TV is not in use. G1 TVs even simulate the look of a picture frame, and the impressive wall mount means there's no gap between the TV and the wall.

That's all well and good, but we were more interested in the evo aspect. Unfortunately we didn't think it made the screen much brighter in our tests.

The design of G1 makes it an expensive option, even without the evo aspect, and LG's C1 and B1 OLED ranges are likely to be more popular.

LG OLED C1

Historically, LG's C range of OLEDs have been its most popular. Since their debut in 2015, each successive C model OLED has been plastered on buses and TV ads, and featured in articles in magazines (including our own once or twice). The same is true of the C1.

TVs in the range feature the same Alpha 9 fourth-gen processor that's found in the G1 series, but they don't have the OLED evo screen. 

We're pleased to see the 48-inch version continuing, so anyone who wants a smaller OLED can get one. 

LG QNED MiniLED 99 8K

LG QNED miniLED 99

It's not just OLEDs that got improvements in 2021: backlit models did, too. By shrinking the size of the LEDs that make up the backlight in its QNED range, LG managed to pack in 30,000 of them. This is a significant increase and should lead to LCD TVs with better contrast control and less blooming, which is where bright parts of the screen spread into darker parts, like a child going over the lines when colouring in.

The fourth-gen Alpha 9 processor is powering this display, so detail shouldn't be an issue in 4K content, but the MiniLED 99 is an 8K set, so the Alpha 9's real challenge is upscaling 4K footage to an 8K standard.

Because it's an 8K set and features a new for 2021 display technology, the MiniLED 99 is expensive and sizes start at 75 inches.

LG's better value 2021 TVs

LG QNED MiniLED 90

8K doesn't get all the fun. The MiniLED 90 is the 4K equivalent to the 8K MiniLED 99. It's a fair bit cheaper as a result.

The processor is different from the MiniLED 99, too. It uses the Alpha 7 rather than the Alpha 9 processor. In theory this should mean colour and detail aren't as good, but in our tests of TVs with previous iterations of the processors we haven't seen a gulf in quality – not a big enough one to warrant the extra expense of buying an Alpha 9-equipped TV, anyway.

LG QNED MiniLED 85

This is the most affordable QNED. It's available in a smaller size than other QNED ranges, although 65 inches is still pretty hefty. It also has a 60Hz screen rather than a 120Hz one. That means the image won't be as smooth when playing games that support such a high frame rate (the number of times per second the screen can refresh the image).

That underlying backlight technology is still the same though, and that's of more interest than the frame rate, since you should see the benefit on everything you watch, not just games and the limited amount of video content that supports 120Hz.

LG Nano90 Nano80 and Nano75

LG Nanocell Nano75 TV
  • Nano90 - any model with 'Nano' in the model name is a Nanocell TV and the Nano90s sit at the top. Nanocell TVs use backlights to create the image, but don't have the tiny LEDs from the QNED ranges. What the Nano90 models have that other Nanocell sets don't is a 120Hz screen. It also uses the Alpha 7 processor, which is the same one powering some of LG's OLED and MiniLED models.
  • Nano80 - the maximum framerate drops from 120 to 60Hz on the Nano80 range and rather than the Alpha 7 processor they get the more generic sound quad-core processor. This could lead to a drop in clarity, contrast and colour on these ranges and motion isn't likely to be displayed as smoothly
  • Nano75 - one thing the Nano75s have going for them is the sizes they are available in. It's the only 2021 Nanocell range with a 43-inch screen option, which is bound to make it popular. Specs wise it shares much with the Nano80, but you don't get local dimming, which means contrast will suffer.

What is the Wallpaper TV?

A TV you can stick to your wall like a roll you just bought from B&Q sounds like a dream come true. 

LG's Wallpaper TV, or W9 to give it's model code, is a thin OLED panel that does have some bend and, with the right wall mount, will sit flush to your wall like paper.

It's able to do this because the speakers and other tech is in a sound bar base that's separate from the TV and connected by one wire. 

The Wallpaper TV doesn't get an annual upgrade like most of LG's lineup, but it's still 4K, supports HDR, but doesn't have all the bells and whistles that the likes of the G2 and C2 range get.

It's pricey, too, with the 65-inch version costing almost £4,000. It is currently out of stock though, so we might be seeing a new version before too long.
