The best 8K TVs sit right at the top of the TV pyramid. They not only offer higher resolution than 4K TVs, but the companies tend to put all their very best TV technology, so you get the best possible contrast and motion processing and everything else that makes for a truly world-class TV.

And we say that the best 8K TVs are world class, we really mean it. The likes of Samsung, LG and Sony are known for pushing the world of TVs to their next level with new tech that brings the latest in flagship performance.

However, while you might think this makes 8K TV prices the preserve of super-yacht owners only, they're actually not beyond the reach of mere mortals. Admittedly, you won't find any in our guides to the best TVs under £1000 or best TVs under $1000, but there is crossover between high-end 4K TVs and more entry-level 8K TVs. 

The high quality of 8K TVs means that they tend to feature heavily in our list of the best TVs overall, though, wrestling with the 4K equivalents for your cash, including the best OLED TVs. And a big part of that that they really are worth the upgrade, despite the lack of actual 4K video.

These 8K TVs are designed around upscaling 4K video beyond the detail that a 4K TV can offer, and they really do achieve it. However, you might still be wondering exactly what 8K TV is, what whether it's worth the fuss – we'll explain more about that now, and bring you the 8K TVs to look out for.

What is 8K TV resolution?

8K TV

8K: a whole lotta pixels

A normal 8K TV will have a resolution of 7680x4320. Just as 4K Ultra HD TVs packed in four times the amount of pixels as Full HD 1080p TVs, 8K quadruples the resolution of Ultra HD.

This is a massive 33 million pixels total, meaning that most people's still cameras aren't even able to fill it natively with a single image – it's that big and detailed.

What exactly does 8K mean in this context? It refers to screens that are approximately 8,000 pixels across, just like 4K refers to screens of around 4,000 pixels. It's not a very precise categorisation, but 99% of the time, when we're talking about 8K, we're talking about the resolutions mentioned above.

All 8K TVs will have advanced upscaling abilities to make sure that 4K or HD content looks good when the resolution is increased to fill the screen. 4K content is relatively easy to upscale for it, but given that only a limited amount of stuff on streaming services and even less on broadcast is available in 4K, upscaling HD will be what really sorts the 8K TVs worth buying from the also-rans. To make things look as good as possible, 8K TVs tend to use 'AI upscaling', and if that sounds like total jargon, then check out our 'What is 8K AI upscaling?' guide.

What does 8K mean in terms of visual quality? Traditional 35mm film is often said to be roughly equivalent to about 6K, so we're beyond the level of detail that the most common film for movies is capable of. IMAX 70mm film is estimated to be more like 12K, but actually the digital effects for IMAX scenes tend to be created in 8K, and if that's good enough for Christopher Nolan, it's good enough for us. If you want a headline description of 8K, it's like having the IMAX experience at home.

8K TV and HDR explained

8K TVs are compatible with the current HDR formats, including HDR10 (the basic standard form), the dynamic HDR10+ upgrade to that, the more broadcast-friendly HLG, Dolby Vision (a more advanced version of HDR that's used on Blu-rays, Netflix and Apple TV), and HDR10+ (a competitor to Dolby Vision used by Amazon Prime Video and some Blu-rays).

Not all TVs will support both Dolby Vision and HDR10+ – most of the best 8K TVs tend to go for one or the other, sadly.

In fact, a lot of 8K TVs will have top-class HDR performance, but this isn't anything to do with the resolution upgrade: it's just that the manufacturers are putting all their best tech into them, which means you get added benefits such as fantastic HDR.

The best 8K TVs: our list

1. Samsung QN900A

Not just the best 8K TV. The best TV you can buy, and a T3 Awards 2021 winner

Specifications
Sizes: 65, 75, 85 inches
Screen tech: QLED
HDR support: HDR10, HLG, HDR10+
Reasons to buy
+Fabulous HDR picture+Incredible backlight with OLED-standard blacks+Plenty of HDMI 2.1 connectivity
Reasons to avoid
-No Dolby Vision

Mini-LED is making waves. The Samsung QN900A, with its Neo QLED panel, is hanging ten on those waves and looking damn cool while doing it: this is an absolutely stunning 8K TV, a flagship in every sense of the word, with an incredible picture, great connectivity, and black levels that basically rival anything in the OLED space. It's probably the best TV ever made, and it won two T3 Awards 2021: Best 8K TV and Best TV of any kind.

Sure, it's missing a few features here and there. It doesn't support Dolby Vision, which is related to Samsung's involvement with HDR10+ rather than something wrong with the QN900A; its support for Dolby Atmos is a little limited, but if you're investing in this, we'd wager you're probably also willing to put some money behind an external Atmos solution anyway.

What you do get is big, it's brash, it's bright and colourful. We reviewed the 75-inch variety, and noted that its HDR performance is class-leading, its 4K upscaling utterly convincing, its peak brightness far in excess of OLED (hitting 4,000 nits at one point) and its contrast absolutely remarkable.

The QN900A is the complete package , as our full Samsung QN900A review explains. It's ready for next-gen gaming, with full HDMI 2.1 support and all the VRR, ALL and FreeSync you can eat; big-screen Playstation 5 games have never looked so good. Sound isn't blow-away great, but in the context of a TV this thin and bezel free (and especially when used in tandem with one of Samsung's Q Symphony soundbars) it sounds pretty darned impressive.

You don't need the 8K functionality here – you could opt for its 4K equivalent, the Samsung QN95A, if you want to save a little cash – but the QN900A does best it in a whole bunch of image quality departments. This is just better. In fact, it's the best.

2. Samsung QN800A

A stunning 8K TV, for a more realistic price

Specifications
Sizes: 65, 75, 85 inches
Screen tech: QLED
HDR support: HDR10, HLG, HDR10+
Reasons to buy
+Excellent upscaling from 4K to 8K+Stunning bright HDR+Gorgeous design with One Connect box
Reasons to avoid
-No Dolby Vision support-Backlight less precise than QN900A

The Samsung QN800A is the model down in Samsung's 2021 range from the QN900A above. It delivers effectively all of the same features, including AI-based processing and upscaling, an advanced sound system, and excellent gaming features including HDMI 2.1 support (with 4K 120Hz and Variable Refresh Rate).

You've still got an ultra-thin design, with the connections and processing all happening in the separate One Connect box, connected to the screen by a single thin cable.

In practice, being the model down means that it doesn't hit the same peaks of HDR brightness, but it remains brighter than almost any other TV on the market today, so still delivers the incredibly vibrancy and realism in bright scenes that we enjoy.

It also features a Mini-LED backlight, and has a huge number of dimming zones to achieve great contrast alongside its brightness, though the precision of the backlight appears weaker than the QN900A, so you get more bleeding of the light from bright areas to dark ones. But, to be clear, that's more bleeding of the light than the LCD TV with the least bleeding we've ever seen. So it's still doing pretty damn well. If you want to see more about how it and QN900A differ, see our full Samsung QN800A vs Samsung QN900A guide.

And, of course, you've got the 33 million pixels of the 8K screen, and the best upscaling we've ever seen for making videos take advantage of it. It's a truly impressive TV.

Best 8K TV: Sony ZH8T3 Award

3. Sony ZH8/Z8H

Astounding images paired with epic sound

Specifications
Sizes: 75, 85 inches
Screen tech: Triluminos LED
HDR support: HDR10, HLG, Dolby Vision
Reasons to buy
+Beautiful, detailed HDR images+Great minimalist design
Reasons to avoid
-No VRR or ALLM for gaming

The Sony ZH8 (UK) / Z8H (US) brings a lot of the key advantages of the ZG9 (below) to a much lower price. This directly competes with the Samsung above for price, and it's a very tempting alternative. The image quality is simply astounding, and when it comes to making SDR sources look like HDR, or making motion looking clearer without the 'soap opera' effect, this is the best in the business.

The upscaling to 8K is truly impressive, though not really any better than the Samsung above. It still really makes the most of the huge screen though. Also impressive is the built-in sound system, which is so much meatier and bigger than just about anything else we've heard, which is a nice bonus.

The support for Dolby Vision is a bonus over the Samsung above, but it lacks HDR10+ support, and does offer support for Variable Refresh Rate, which is a great feature of the PS5 and Xbox Series X. However, it does support 4K at 120Hz.

4. Sony ZH9 Master Series

Master by name, master by nature

Specifications
Sizes: 75, 85 inches
Screen tech: Triluminos LED
HDR support: HDR10, HLG, Dolby Vision
Reasons to buy
+Big, bright HDR images+Excellent processing 

An incredible TV, making use of every inch of Sony's screen know-how… and boy does Sony have a lot of screen know-how. It comes in 75-inch or 85-inch sizes, which will really make the most of the giant resolution.

It's an LCD screen, and uses Sony's Full Array Backlight Master Drive tech, which means there's a full panel of LEDs behind the screen (rather than strips around the edge). This makes it thick for a modern TV, but has two big advantages: it means it can go very bright, but can also turn off in individual sections so that it can go very dark, too. Basically, it gives you close-to-OLED levels of depth, but with brighter highlights than OLED can manage.

And it's got Sony's most advanced upscaling and motion handling technology so that everything looks perfectly clear. It's one of the best TVs we've ever seen, but like other 8K TVs, it costs – £5,999/$6,999 for the 75-inch, £8,999/$9,999 for the 85-inch.

A new version, the Sony ZH9, has been announced to replace it – probably in late 2020. It adds a clever new audio system that uses the frame of the TV itself to act as a speaker, plus it automatically optimises the TV's image based on the room it's placed in, changing brightness when the room gets lighter, for example.

Best 8K TV: LG ZX 8K OLED TVT3 Award

5. LG ZX

The 8K OLED TV to watch in 2020

Specifications
Sizes: 77, 88 inches
Screen tech: OLED
HDR support: HDR10, HLG, Dolby Vision
Reasons to buy
+Incredible thin design+Amazing realism in contrast+Impeccable per-pixel detail
Reasons to avoid
-Not as bright as LED screens-VERY expensive

Order the 77-inch LG OLED77ZX for £24,999 from PRC Direct
Order the 88-inch LG OLED88ZX for £39,999 from PRC Direct

LG introduced the world's first OLED 8K TV last year, and this is the 2020 version, with improved processing. Available in 77-inch or 88-inch models, it's a bit of a design wonder: the screen itself is ultra thin despite being massive, which means the 88-inch model actually has a stand (with built-in speakers) that you can't detach it from – the structure is crucial to keeping the thing in one piece. The 77-inch model can be wall mounted, though.

It's equally a wonder to watch anything on. All the advantages of OLED are here – perfect per-pixel colour accuracy and incredible contrast – but in a huge beautiful screen that washes over you.

LG's image processing for upscaling and dealing with motion blur is excellent too – this deserves to be the centrepiece of any room. And since it costs from £25k for the 77-inch version, you'd hope so, wouldn't you?

6. LG Nano95 8K LCD TV

A bargain way into 8K with LG top-end features

Specifications
Sizes: 55, 65 inches
Screen tech: NanoCell LED
HDR support: HDR10, HLG, Dolby Vision
Reasons to buy
+Tons of 8K detail for less+All of LG's top-end processing+Great webOS software
Reasons to avoid
-Not as bright as higher-end 8K sets-No giant screen sizes

Order the 55-inch LG 55NANO956NA from PRC Direct for £1,999
Order the 65-inch LG 65NANO956NA from PRC Direct for £2,999
Order the 55-inch LG 55NANO956NA from Hughes for £2,499
Order the 65-inch LG 65NANO996NA from Hughes for £2,999

LG's entry-level 8K TV range features the same Alpha 9 Gen 3 processor as its extravagant OLED 8K TVs, and the more expensive LCD 8K sets below, but with slightly less advanced panel tech for brightness, and it comes in smaller sizes.

The result is that you get all the detail of 8K, but in a TV that's easier on the budget, and is suitable for smaller rooms.

This is great choice for gaming too – it's packed with features ready for the PS5 and Xbox Series X, including HDMI 2.1 support, which means you can play 4K games at 120Hz, but both consoles have also claimed 8K support, so if you want an affordable way to play whatever 8K games may be available, here you go.

7. LG Nano99 8K LCD TV

Sharp 8K from a great brand

Specifications

Screen tech: NanoCell LED
HDR support: HDR10, HLG, Dolby Vision
Reasons to buy

Order the 75-inch LG 75NANO996NA from PRC Direct for £5,499 

LG's equivalent to the Samsung screens above, this is LG's flagship LCD TV for 2020. There are 65-inch and 75-inch models, so while it's premium priced, LG is sticking with models that are more likely to fit in someone's house in real life.

Like both the Sony and Samsung, you get a full array backlight with local dimming, though this screen hasn't garnered quite the plaudits those have. You'll also have LG's latest-gen image processing – the same as you'll find in the OLED flagship sets.

8K TV: what can I watch?

In native, pure, 8K? Effectively nothing. Even recently, Hollywood has tended to use 6K cameras even when working digitally (and, as we suggested earlier, old films can only really be re-scanned to 6K, though they can then be upscaled, which can be highly effective), so content isn't exactly about to explode, either.

Japan was due to trial the first 8K public broadcasts this year for the Olympic Games, but that's obviously not going to happen any more. Similarly, BT Sport has shown off a live 8K broadcast of a football match in the UK, and announced that it expected to be able to show the 2020/2021 football season in 8K on dedicated channels, but everything's up in the air there due to the pandemic disruption, too.

There are no plans for an 8K disc format currently. Vimeo does now have 8K support for videos, though, and YouTube likes to be at the forefront of these things, so 8K streaming looks to be the future, assuming your internet can handle it.

Samsung is developing a technology called ScaleNet that's designed to make 8K easier to transmit over limited connection speeds, and is especially interesting. It works by using an 'AI' at the transmission end to downscale the image to 4K, then a matching 'AI' that knows exactly how the first one works to upscale it back to 8K – this should preserve more detail than a regular compression algorithm.

We should say that it increasingly looks like the industry may move away from worrying about native resolution, now that upscaling from lower resolutions is becoming so advanced thanks to machine learning. As long as an 8K screen is good enough, it will still offer an advantage no matter whether you throw it HD, 4K 6K or full 8K.

All of the above only solves getting the image to you, not recording it in the first place! We're seeing the first consumer cameras with 8K recording in arriving now: the Samsung S20 Ultra includes it, as does the LG V60 ThinQ phone, and the Canon EOS R5 mirrorless camera.

8K gaming: PS5, Xbox, PC

Gaming in 8K is sort of possible, if you have a ridiculously powerful PC – you'll need two (at least) of the highest-end graphics cards running in tandem, and the games you play will have to have solid support for it.

Both of the next-gen consoles – Sony's PlayStation 5 and Xbox Series X – have promised to support 8K, but don't expect that to mean that every game will have a true 8K output. That level of power just isn't possible in small boxes right now. 

But they will definitely have 8K HDMI support, and may use smart upscaling techniques (similar to what's used now by the PS4 Pro for some demanding 4K games) to create something that looks impressively close to 8K. Time will tell.

So, really, you'll mostly be upscaling existing content. But with a really good upscaler from a 4K video, you actually can still make the most of those extra pixels, especially on a really big screen. It won't look as good as native 8K, but it will look better than 4K, and on a big screen size, that's an improvement worth having.

8K TV: what HDMI cable do I need?

Now this is an important – and sexy – question. You can't use the one that came free with your DVD player in 2011, but there is a new HDMI standard that's capable of pushing the number of pixels required for 8K over a single cable. It's called HDMI 2.1, and it has three times the bandwidth of previous HDMI connections. 

HDMI 2.1 is backwards compatible with previous HDMI connections, so it's all good for 4K or Full HD using your existing cables, but if you want to connect an 8K source to it, you may need a new higher-speed cable. Cables that are certified to use the full bandwidth of the new connection type are labelled Ultra High Speed HDMI. Whoah.

8K TV: is it worth upgrading?

It really could be, but not for the reason you'd assume. Normally, a big resolution jump comes, and we recommend upgrading so you can see beautiful videos in the new resolution… but we've already said that's not the case here.

No, the reason you should buy the one of the best 8K TVs (ie the ones listed above) is because they represent the pinnacle of TV tech – buy them because you want the finest motion processing, HDR performance and colour reproduction known to man. Buy them if you want the best TV available, regardless of resolution.

That's not to totally discount that the higher resolution could be a benefit for you, though. There's a good reason 8K TVs often come in bigger-than-65-inch sizes – that's where you'll see the biggest improvement over buying a 4K TV.

If you live in an average-sized home, with a 50- to 65-inch TV maximum, it's not going to be worth it just for the number of pixels, unless you want to sit really close to the screen and pick on every drop of detail.

But if you've got a bigger space, and are looking at 70-inch+ TVs (or even projectors, since there are 98-inch 8K TVs available), or simply if you want the best TV tech going, then an 8K TV is seriously worth considering.
