Best TV 2022: the best 4K Ultra HD TVs you can buy right now

Best TV Buying Guide: Welcome to What Hi-Fi?'s round-up of the best TVs you can buy in 2022.

While buying a new TV certainly can and should be an absolute thrill, there's also one major problem: there are so many darn models, types and sizes to choose from that it can be almost impossible to work out which is best for you. Fear not, though, as we're here to help – before you tumble down the well of indecision, allow us to take you by the hand and lead you along the path to TV utopia.

We've run the rule over all the major 4K and 8K televisions we've tested to bring you the cream of the crop. If a TV is on this list, it's a bona fide belter, so you know you're getting top bang for your buck.

Towards the bottom of this page, below the specific TV recommendations, you'll also find our dedicated guide to choosing the right TV, but here's the abridged version.

How to choose the best TV for you

There's a huge amount to consider when choosing a new TV, but the biggest things are the money and space that you have available.

Size really does matter with TVs. Are you looking for a movie theater-like experience in your lounge? Then you need to get the biggest TV you can afford. If your budget is limited, it might even be worth sacrificing a little bit of picture quality and next-gen display tech for a few extra inches of screen real estate.

Alternatively, you might have a specific size of TV in mind and an appetite for the best picture quality available. In that case, you need to prioritize the display technology.

Without a doubt, OLED has become the premium TV technology of choice, thanks to its perfect blacks, extraordinary contrast and exceptional viewing angles. QLED, which combines LED (or Mini LED) backlighting with ultra-vibrant Quantum Dots, is a strong alternative, though, largely thanks to being capable of greater brightness and punchier colors. Standard LCD TVs (often, confusingly, sold as 'LED' TVs on account of their LED backlights) are more variable in overall quality but, if you shop carefully, can offer excellent bang for your buck.

Are you planning to combine your new TV with a dedicated sound system? You probably should, because most TVs sound passable at best, even at the high-end. But if you're determined to keep things neat and rely on the in-built speakers, check our reviews to make sure that they're good – there's no point in a great picture if the accompanying sound is terrible.

If you're a gamer, it's also worth considering the next-gen gaming features of your prospective new TV. Xbox Series X and PS5 gamers can gain a competitive advantage on certain games if their TV supports 4K 120Hz, while VRR support can result in a smoother gameplay experience. ALLM, meanwhile, simply ensures that you automatically get the best visual experience from both games and movies / TV shows. If you're a more casual gamer or not a gamer at all, you can pretty much disregard these features, and doing so will likely save you a lot of cash.

Reasons to avoid

-
Substantially pricier than the C2
-
Not as bright as premium LCD TVs
-
No stand in box

While not a change that all buyers appreciated, LG decided in 2021 that its premium G-series OLED TVs needed more than just a fancier design to make them a compelling step-up alternative to the brand’s all-conquering C series.

So 2021’s G1 benefited from a new, higher brightness ‘Evo’ panel that the C1 did not get – and instantly did a much better job of justifying its higher price. 

LG has continued this approach for 2022: while the new C2 does now have an Evo panel, the G2 boasts a new heat sink element that allows it to be driven even harder – or brighter, in other words – than its predecessor.

In short, if you want LG’s best 4K OLED TV in 2022, this is it.

The OLED65G2 is easily LG’s best OLED TV yet. Its sound is a solid improvement over LG’s 2021 built-in audio, while the extra brightness it achieves thanks to its new heat sink and accompanying new processor delivers nothing but positives, enriching everything from basic HD SDR to sparkling 4K HDR and the finest graphical wares of the latest gaming consoles and PCs. All without anything looking forced or like ‘brightness for brightness sake’.

The extent of the improvements over the new C2 panel is more gentle than dramatic, perhaps raising questions for many about whether the OLED65G2 is worth $700 more than the OLED65C2. The cost issue is even more worthy of thought if you’re not wall-mounting and will therefore need to budget for the optional stand. 

While not truly extreme, though, the OLED65G2’s advantages are not only easy for anyone to see, but crucially lift pretty much every image frame to a higher level. So if you’re an enthusiast who just can’t rest unless you know you’re getting the best home theater experience available, the OLED65G2 is going to be seriously hard to resist.

Charge of the bright brigade

Reasons to buy

+
Good value
+
Sounds impressive for its size

Reasons to avoid

-
Blacks could be deeper
-
Some backlight blooming

The X90J’s pictures aren’t exactly shy and retiring – and that’s fine by us. Exceptional amounts of brightness make it onto the screen with startling consistency, delivering some of the most flat-out punchy and bright HDR pictures we’ve ever seen on a 50-inch TV.

It’s not just brightness for brightness sake, either. Sony is unashamedly using it to deliver as uncompromising an HDR experience as it can within its backlight limitations. So daylight HDR scenes look more natural and realistically bright by far than they do on any other current TV in its size and class.

Even more impressively, the XR-50X90J has enough headroom with its brightness to ensure that the brightest highlights of already bright HDR images enjoy that extra step up in intensity that usually only the most premium TVs provide.

The price you pay for this superb brightness is slightly elevated black levels and occasional backlight blooming, but neither issue is a huge deal-breaker, and you can also add excellent motion processing, natural colors and decently dynamic sound to the list of the Sony's strong points.

It's also got two HDMI 2.1 ports that support 4K at 120Hz and, since a software update, VRR.

Not as good for gaming as an LG

We rate products on a performance-per-dollar basis. That’s always been the What Hi-Fi? way. We’re not looking simply for the absolute best product in each category, as that would invariably involve recommending one of the most expensive products in each category; we’re looking for the best bang for your buck. The product that best balances performance, features and price.

On that metric, the A80J is a stunner. This step-down model in Sony’s 2021 OLED range certainly isn’t quite as good as its flagship sibling but, by offering most of what makes the A90J great at a much more competitive price, it’s turned out to be one of the very best TVs you can buy.

While not quite as bright and punchy as its flagship sibling, it's not far off, and that means it's still capable of producing more impactful highlights than rivals such as the LG C1. It's just as sharp and detailed as the A90J, too, which makes it an incredibly crisp and three-dimensional performer. What's most impressive is how the A80J combines the spectacular with the natural and authentic – no other TV available right now, bar the A90J, delivers on creative intent as faithfully.

The A80J has a 30W Acoustic Surface Audio+ sound system, which uses actuators to vibrate the screen in order to create sound. It means the audio is tied to visuals in a way that TVs from other manufacturers can't match. The sound is also weightier and more spacious than that produced by similarly priced rivals, and there's impressive punch and dynamic range on offer, too.

Marginal gains on 2020's CX

Unengaging audio

LG’s C-series model has been the go-to pick of its OLED range for several years. It has always been the most affordable model with the company’s best panel and picture processing wizardry. Spending more would get you a fancier design and potentially better sound, but the picture would be no different.

That’s not the case now. In 2021 LG introduced a new, brighter and sharper ‘OLED Evo’ panel, and the C1 doesn’t have it.

With so much of the focus on the upgraded G1, it’s perhaps predictable that the C1 isn’t much of an improvement on its predecessor, but there wasn’t much that needed improving. The picture performance and feature set were already exemplary, and LG has slightly improved the former with its new Cinematic Movement motion processing and enhanced de-contouring feature (which reduces banding), and slightly improved the latter with a better menu system and a more complete app selection.

The G1's picture is undeniably better in terms of brightness, sharpness and detail, but we're not talking huge margins and most people will struggle to justify the extra $500, particularly when the niche design and weaker sound are taken into account.

Ultimately, in bang-for-buck terms, the C1 is the better buy. In fact, it's one of the very best TVs available right now.

We've now tested the C1 in its 65-inch and 48-inch sizes, and both are equally brilliant. While we can't say it with total assuredness, we would expect the 55-inch and 77-inch models to be equally strong.

LGs make better gaming TVs

Expensive

While Sony’s OLEDs are highly regarded, it’s typically hard to justify buying one over a rival LG. Historically, the Sony has a more authentic picture and better sound but is also a step behind on features and usability – and at least a level or two more expensive.

But what if Sony could produce a TV with most of those previously missing features, a more satisfying user experience, and a unique high-quality movie streaming app, all while raising the picture and sound quality to even greater heights? That's exactly what the company's done with the A90J.

In performance terms, the Sony A90J is an absolute stunner. It took OLED picture performance to new, thrilling levels when it launched in 2021, while maintaining the authenticity for which Sony is justifiably renowned. It also sounds significantly better than all of the other TVs you're likely considering. The new Google TV operating system means the user experience is better than that of any pre-2021 Sony TV, too, and the exclusive Bravia Core streaming service is a genuine value-added feature.

Do check out the A80J above before handing over your money, as it offers much of (but not all) the A90J's excellence at a significantly lower price. However, if your pockets are deep and your tastes discerning, you won't regret spending the extra on this flagship beauty, which we've now tested in both its 55-inch and 65-inch guises.

There’s no substitute for size when it comes to home theater. After all, the whole goal of ‘home theater’ is to, you know, bring the movie theater home. And what’s the most important part of the movie theater experience? The whopping huge screen, of course. That’s why a 65-inch TV (or even bigger!) is what you should aim for if you’re looking to add some serious cinematic scale to your living room.

But we can’t all afford to go big and go super-premium. Your budget might stretch to a 65-inch TV, but perhaps not a 65-inch OLED or flagship QLED. If that’s the case, the Sony XR-65X90J could be just what you’re looking for thanks to its heady mix of fancy features, perfectly-pitched picture performance and a mid-range price tag.

Those features include two HDMI 2.1 sockets that support 4K@120Hz and VRR, and the new Google TV operating system. The picture is brilliantly natural, authentic and balanced, and the sound is clear and direct too.

While you could buy a 55-inch OLED for similar money, it’s perfectly reasonable to instead choose to go for a TV that’s a little less premium but a full 10 inches bigger. If that’s the choice you make, the X90J absolutely demands your attention.

Reasons to avoid

No feet or stand in the box

Sound lacks excitement

Traditionally speaking, the C-class model is the sensible choice of each new LG OLED range. Until 2021, it was the most affordable model with the latest panel and picture processing tech: go further up the range and you might get better sound and a fancier design, but you wouldn't get a better visual performance.

For 2021, though, LG introduced a new ‘OLED Evo’ panel that promised increased brightness and sharpness, and to get the Evo panel you had to step up to the G1. That was slightly disappointing because you also ended up paying extra for a rather niche design (the G1 is designed to be wall-mounted, to the extent that there's no stand or feet in the box) that you may not want.

Still, if the design works for you and you don't mind forking out the extra cash, the G1 is undoubtedly the best OLED LG of the 2021 range, taking the picture performance of 2020's GX and CX and improving upon it in almost every way, particularly in terms of brightness, sharpness and detail. That makes it a seriously stunning picture performer. It's also packed with apps and next-gen HDMI features, including 4K@120Hz on all four sockets.

Sound is less strong, but if you were always planning to combine your new TV with a separate sound system and the design works for you (and you've got deep pockets), the G1 should be seriously considered. Do, however, also consider the new C2, which has the brightness of the G1 in a more traditional chassis, and the G2, which is a further step-up in picture performance.

We tested the G1 in its 65-inch size. It's also available as a 55-inch and 77-inch model.

Expensive for its size

We'd been waiting for this moment for a long time. After years of biding its time, LG finally launched the first 48-inch OLED TV in 2020, bringing true flagship OLED TV performance to under 55 inches for the first time.

And it really is a fabulous performance. This isn't a downgraded flagship TV – it's a downsized flagship TV. It offers the same performance and features as its bigger brothers in the CX range (which, let's remember, also match the more expensive GX, RX and WX in terms of picture quality and processing), but in a smaller, more living room-friendly package.

The performance is superb. The perfect blacks and near-perfect viewing angles we're used to from OLED combine with bright, punchy whites and vibrant but natural colors. LG's 2020 motion processing is the best it's ever been, too, and its OLEDs continue to impress in terms of upscaling 1080p and standard-def content.

On top of all that you get certified HDMI 2.1 sockets that support next-gen features such as eARC (Enhanced Audio Return Channel), HFR (High Frame Rate), ALLM (Auto Low Latency Mode), and all current formats of VRR (Variable Refresh Rate). Those last two features will be of particular appeal to those gamers looking to upgrade to the PS5 or Xbox Series X.

Chocolate and peanut butter, beer and chips, sleep and Sundays – some things are perfect partners, whether they were designed that way or not. Samsung’s 8K boffins might not be the same people as those in charge of Mini LED, but together they have managed to create one serious winning combination in the Samsung QN75QN900A 8K TV.

The Samsung QN75QN900A is a 75-inch version of Samsung’s third generation of 8K TVs, but the first to be backed by a Mini LED lighting system. As the name suggests, Mini LEDs are much smaller than standard LEDs, the size of glitter in your hand, and numbering in the thousands, rather than the hundreds, on your TV panel.

In the case of the QN900A, More LEDs means more granular backlight control, and more pixels means crisper definition. Forget native 8K content for now, because there isn't any – focus on the fact that this fabulous TV manages an awesome sense of scale but with the sort of sharpness and detail that we’d normally associate with a smaller 4K set. If you're going really big with your next TV, this is the model to get.

We tested the QN900A in its 75-inch size. It's also available as a 65-inch and 85-inch model. We've not yet reviewed these versions but you'll see the latest, lowest prices below.

Reasons to avoid

-
High-contrast images lack punch
-
Lacking next-gen HDMI features

This set is practically all screen – the black bezel is flush with the screen so you don’t notice it when the set is off. The fact it's so thin puts the emphasis squarely on the screen.

And what a screen it is. Images are beautifully natural, lending themselves to a theatrical authenticity that's great for movies. Dark detail is a particular highlight, though in high contrast sections (like white credits on a black screen) the Sony tends to play it a little safe. We would've liked more punch.

Typically for a Sony, the motion processing is superb, and SDR content remains vibrant and dynamic. It even makes standard definition content watchable. Just.

On the audio side, the A8 lacks a little bass depth and weight, but otherwise impresses with its crisp, dynamic delivery. It sounds a lot better than most of its similarly-priced rivals, though of course we would always recommend partnering it with a dedicated sound system to really enhance the experience.

If you’re looking for something small for a bedroom or perhaps even to fit out a motorhome or camper, then this budget Roku TV-powered TCL may be just the size and price you need.

You won’t find much smaller or cheaper from a recognized manufacturer and, in TCL, you’re getting a TV from a maker that’s on the up.

The software comes in partnership with Roku, whose operating system provides the platform for all the settings and controls as well the apps and service, while the hardware is TCL. This rock-bottom price only gets you 720p resolution, but that could be all you need.

While there are a lot of cheap TV pitfalls, TCL has done well to avoid most of them. The backlighting is even, the picture is balanced and the sound is clear enough. Its colors lack subtlety and its motion handling is pretty poor but, for the very small size and price, this is a good option.

How we test TVs

How we test TVs

Testing a TV is a long and complex process because a modern TV simply does so much. Not only does it need to handle a variety of content resolutions – standard-def, 1080p, 4K and sometimes 8K – and both standard dynamic range and high dynamic range (the latter in a number of formats), all of which need to be specifically tested, is also has a sound system with various advanced settings and a full smart platform. A TV is all-in-one devices in the best sense, but that also makes it a challenging review proposition.

As part of our testing process we manually check that every major app – from Netflix to Hulu, Prime Video to Spotify – is not only present, but also outputting in the video and sound formats that it should. Just because there's a Disney+ app doesn't necessarily mean it's working in Dolby Vision and/or Dolby Atmos. In fact, in many recent cases it hasn't been.

We also connect both a PS5 and Xbox Series X in order to establish which advanced gaming features are and aren't supported, and on which of the TV's HDMI ports. Is 4K 120Hz supported? How about VRR? Is there a Dolby Vision game mode? Is there an HGiG preset for more accurate HDR tone mapping? We check all of these things, and measure input lag using a Leo Bodnar device.

We then test the TV's picture quality using a huge variety of content, from old DVDs to the latest 4K Blu-rays and plenty of streamed movies and TV shows in between. Every TV is tested against the best model at its price and size – we have a stockroom packed full of Award-winners for this very purpose.

We don't accept the out-of-the-box settings that a TV comes in either. While we intentionally don't go down the route of professional calibration (you shouldn't have to have your TV professionally calibrated in order to get the best out of it), we do spend hours adjusting settings using a mixture of test patterns and real-world content until we're sure we're getting the best out of a TV so that it has the best chance to shine.

While we almost always advise that a new TV is combined with a dedicated sound system such as a soundbar or AV amplifier, many people still prefer to stick with their flatscreen's built-in speakers, so we thoroughly test these too, using a wide variety of movie and music content and with great attention spent to the TV's many processing modes and individual settings.

We have state-of-the-art testing facilities in London, Bath and Reading, where our team of expert reviewers do all of our testing. This gives us complete control over the testing process, ensuring consistency. What's more, all review verdicts are agreed upon by the team as a whole rather than an individual reviewer, again helping to ensure consistency and avoid any personal preference.

The What Hi-Fi? team has more than 100 years experience of reviewing, testing and writing about consumer electronics.

From all of our reviews, we choose the best products to feature in our Best Buys. That's why if you take the plunge and buy one of the products recommended below, or on any other Best Buy page, you can be assured you're getting a What Hi-Fi? approved product.

How to choose a TV

What size TV should you buy?

While it might be tempting to think that bigger is better, the size of set that’s right for you is closely dependent on how close to the screen you’ll be sitting, and the resolution of the source material you’re watching.

Luckily, an organisation called SMPTE (which stands for the Society of Motion Picture and Television Engineers) has published detailed guidelines on exactly how far you should sit in order to optimize the performance of your TV.

If you’re sitting the correct distance from your TV, you’ll see lots of detail, good edge definition and smooth, clean motion, but if you’re sitting too close to the screen, then you’re going to see more picture noise and artefacts.

On the other hand, sit too far away from the TV and you’ll struggle to pick up all the picture detail your TV has to offer.

The following distances are a good place to start:

  • 65-inch TV – minimum 98 inches (Full HD) or 83 inches (4K)
  • 50-52-inch TV – minimum 87 inches (Full HD) or 67 inches (4K)
  • 46-inch TV – minimum 75 inches (Full HD) or 59 inches (4K)
  • 40-42-inch TV – minimum 67 inches (Full HD) or 51 inches (4K)
  • 32-inch TV – minimum 51 inches (Full HD)

Should you buy a 4K or Full HD TV?

This question is pretty much moot now, as the vast majority of TVs are now 4K. It's actually rather hard to find Full HD (1080p) models, even at relatively small sizes.

If you're buying a TV below 32 inches and can save a lot of money on a Full HD model, by all means go for it (4K won't be a huge benefit at that sort of size anyway), but otherwise 4K is both worthwhile and, in all likelihood, your only option.

Should you buy an 8K TV?

You can now buy 8K TVs from a number of brands, including Samsung, LG and Sony. It's arguably Samsung that has lead the way, and our favourite 8K TV so far is the excellent QN75QN900A.

It's important to note, though, that almost no native 8K content is available. If you buy an 8K TV and want to show of its ridiculously high resolution, you'll have to do so using nature, scenery and space footage from YouTube. At this stage, no streaming services have even hinted at launching 8K content, and it seems unlikely that an 8K disc format will ever materialize.

For those reasons, it's hard to recommend that most people pay the extra for an 8K TV at this stage. That said, if you've got deep pockets and want to be as ready as possible for the potential 8K content of the future, there's no real harm in going for an 8K TV now, particularly as models such as the Samsung QN900A make current 4K content look better than ever.

Should you buy an HDR TV?

High Dynamic Range is without a doubt a much bigger deal than 8K, and certainly something you should consider before buying your next TV.

Essentially, the higher the dynamic range (brightness and colors), the more lifelike the picture. HDR offers greater subtlety and depth of gradations of colors, plus stronger contrast.

There are various types of HDR out there, and with different TV brands backing different variants, it can be a minefield trying to find the best option. Allow us to explain.

First up is HDR10, which is essentially the core HDR format that every HDR TV should support.

HDR10 is a static HDR format that applies the HDR values on a scene-by-scene basis (i.e. whenever the camera cuts to a new scene). Dolby Vision, on the other hand, applies this image information (called metadata) on a frame-by-frame basis. This dynamic form of HDR, when implemented properly, has the potential to improve upon the standard HDR10 presentation.

HDR10+ is a rival format to Dolby Vision. Created by Samsung, it also uses dynamic metadata but, whereas Dolby Vision is licensed, HDR10+ is a free, open format that any company can deploy as it sees fit.

Of these two 'dynamic' HDR formats, Dolby Vision is by far the most prevalent, both in terms of TVs and content, and if you have to choose between one and the other, that's the one we'd recommend. That said, you can now buy TVs from the likes of Philips and Panasonic that support both Dolby Vision and HDR10+.

Finally in our rundown of HDR formats is HLG (Hybrid Log Gamma), which was developed specifically for broadcasting by the BBC and Japan's NHK. In the UK, HLG is used to deliver all of the HDR content offered by the BBC and Sky, but it's less widespread in the US, with DirecTV really the only major player that's adopted the format.

What TV inputs and outputs do you need?

These days, it's all about HDMI, which is used to connect everything from set-top boxes to video streamers, Blu-ray players to games consoles. Thanks to ARC/eARC (Audio Return Channel / Enhanced Audio Return Channel), a single HDMI connection can even be used to output sound to an AV receiver or soundbar at the same time as it receives a video signal.

Currently, three HDMI connections is standard on budget and mid-range TVs, while four is the norm for premium models.

The specification of the HDMI connections tends to differ depending on the price of the TV, too, with premium models now commonly getting at least one or two HDMI 2.1 sockets. These have greater bandwidth than their HDMI 2.0 counterparts and can support advanced formats such as 4K@120Hz and 8K@60Hz. Fancy gaming features such as Auto Low Latency Mode and Variable Refresh Rate are often supported via HDMI 2.1 sockets, too, though not always. It's sensible to check the specs thoroughly if there are particular features you're after.

After HDMIs, USB ports are the most abundant on modern TVs. You can use these to keep devices charged (often particularly useful for stick- or dongle-style video streamers), and some TVs allow the connection of flash drives and hard drives for the recording of live TV content.

Other useful connections include optical and stereo outputs, which can be used in lieu of HDMI ARC to connect legacy audio equipment. Headphone outputs are still fairly common, too, though Bluetooth is also supported by most TVs now and Samsung TVs in fact now feature the latter but not the former.

Lastly, while some TVs feature composite inputs (often via an adapter), most – even at the budget end – have phased out legacy connections such as SCART. So those clinging on to old video cassette recorders, for example, should be aware of that.

Which smart features and TV streaming apps are worth having?

As with 4K, it's now hard to buy a TV that doesn't have a smart platform packed with streaming apps. Almost every TV will have Netflix and Amazon Prime Video on board, and Disney+ is fast approaching a similar level of ubiquity. Apple TV (which is great for pay-as-you-go movies as well as the Apple TV+ subscription service) is becoming increasingly common, too.

Beyond those, you're going to want to look out for services such as HBO Max, Hulu, Paramount+ and Peacock, with priority given to those services to which you already subscribe.

Should you buy an OLED, QLED or LCD TV?

LCD TVs, which require a backlight usually made up of white LEDs to show a picture on the LCD panel, are available in a wide variety of screen sizes and, thanks in part to the technology's low cost of production, at affordable prices.

OLED (Organic Light-Emitting Diode) is a panel technology that uses self-emissive particles – so there's no need for a backlight. This allows OLED TVs to be unbelievably slim, while also offering convincing pitch-dark blacks, strong contrast and superb viewing angles. LG and Sony are the big brands with OLED TVs in their line-ups and, broadly speaking, they're excellent.

QLED (Quantum-dot Light-Emitting Diode), meanwhile, is Samsung’s response to OLED. A QLED TV is an LCD TV but with a quantum dot coating over the backlight. However, the quantum dots (tiny semiconductor particles) in current QLEDs do not emit their own light. So QLED TVs, like conventional LCDs, rely on a backlight. The advantages of a QLED TV? You tend to get brilliantly vibrant colors, plus bright, sharp and crisply detailed images. Samsung's QLEDs have got better and better over the years, existing as a fine alternative to OLEDs TVs. Interestingly, though, Samsung is set to launch its own OLED TVs in 2022.
