Best 8K TV 2024: we tested the big names and only two are worth considering

Samsung QE75QN900D 8K TV.
Best 8K TV: Quick Menu

Early adopter looking to secure bragging rights as one of the first cinephiles to own an 8K TV? Then you’re in the right place as in this guide our team of experts rate the top 8K TVs they’ve tried and tested.

As a second bit of good news, we can also confirm for the first time that there are some great 8K TVs doing the rounds for buyers that want the most modern cutting edge tech available and don’t mind paying a premium for it a – as evidenced by the return of the category in our current What Hi-Fi? Awards 2024.

However, if you’re a normal movie fan who has stumbled on this page, we have some simple advice – jump over to our main best TV or best OLED TV buying guides instead.

Why? Because though there are 8K TVs being made, there’s next to no content mastered at the resolution, so if you’re just after a top end TV you’ll almost certainly be better off saving your money and opting for a regular 4K set.

The only advantage you get with 8K is future proofing and advanced upscaling – the latter of which can be a bit hit and miss in its attempt to sharpen 4K content, depending on which set you use.

Samsung QN900D

The best 8K TV overall and a What Hi-Fi? Awards 2024 winner

Screen size: 75 inches (also available in 65in, 85in) | Type: QLED | Backlight:: Mini LED | Resolution: 8K | HDR formats: HLG, HDR10, HDR10+ | Operating system: Tizen | HDMI inputs: x 4 (4 x 48Gbps HDMI 2.1) | Gaming features: 4K/120Hz, VRR, ALLM | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 94 x 165 x 1.3cm

Groundbreaking 8K upscaling
Exceptionally bright and colourful
Stunning futuristic design
Average sound quality
No real 8K content
Backlight-dimming distractions in some presets

If you want an 8K TV and don't mind paying a premium then the Samsung QN900D is the one to get. During testing it proved to be the best 8K TV our team of experts has ever tested, a fact evidenced by it winning a What Hi-Fi? Award this year.

During testing we found it is a big upgrade on Samsung’s past 8K TVs. 

Key improvements include a Mini LED panel with more dimming zones, which grants more granular control of which pixels are being charged. The processor has also been upgraded to the latest-generation Neo Quantum 8K AI Gen 3, which is twice as fast as its predecessor.

What do the upgrades mean for the QN900D’s real-world performance? A lot, based on our experience reviewing it. Our testers went so far as to report: “Samsung’s new flagship TV suggests 8K is far from dead.”

Key improvements include noticeably more accurate colours – even when watching difficult Dolby Vision HDR movies, such as Mad Max: Fury Road – great motion handling, and radically improved upscaling.

The last of these surprised us the most and makes the QN900D the easiest 8K TV to recommend. This is because, as there is next to no native 8K content available at the moment, the primary benefit you enjoy when investing in a higher-resolution 8K TV hinges on its ability to upscale 4K and FHD content. 

Traditionally this has been an issue as the upscaling process injects some artificiality into the image. Not with the QN900D, though; our testers report:

“Its picture quality improves considerably in just about every way on its predecessor, crucially leaving clear blue brightness water between it and 2024’s top OLED TVs, and rewriting the upscaling rule book to remind us in no uncertain terms that 8K TVs don’t have to be fed 8K content to make a difference.”

The only downsides to the set are that you are paying a premium for the next-generation resolution, and the TV’s slightly lacklustre sound. It simply doesn’t do justice to the wonderful immersive picture it delivers.

2. LG Z3 (OLED77Z3)

The best 8K OLED TV

Screen size: 77 inches (also available in 88 inches) | Type: OLED (with MLA) | Backlight: not applicable | Resolution: 8K | HDR formats supported: HLG, HDR10, Dolby Vision | Operating system: WebOS 23 | HDMI inputs: x4 (all HDMI 2.1) | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 98 x 172 x 3.3cm

Gorgeous, incredibly detailed picture
Strong upscaling performance
Luxurious design
It’s painfully expensive
It’s not as bright as expected
Slightly inhibited audio performance

If the Samsung QN900D wasn’t premium enough to get you reaching for your wallet, then the LG Z3 is the only other 8K TV we have tested that we believe is worth considering. It scored four out of five stars; a large part of this was down to its hefty cost, which makes it a hard sell for anyone but the most cash-rich of buyers. But, if you do have the money, it does come with one key benefit over all its Samsung rivals: its use of a micro lens array (MLA), OLED panel.

If you jump over to our regular best TV and best OLED TV pages you will see this is a big deal, as OLED offers one key advantage over Mini LED: it can produce perfect blacks. This is by merit of the hardware’s ability to charge individual pixels rather than zones or an entire backlight. While we really wouldn’t recommend anyone but the richest buyer consider it, there’s no denying the Z3’s picture is amazing.

Using a test reel of native 8K content provided by LG and our usual assortment of 4K test discs to check its upscaling prowess, our testers were uniformly impressed, going so far as to report:

“Viewed in isolation, the LG OLED77Z3 is in many ways a thing of beauty. Its 8K resolution both brings out the best of OLED’s self-emissive technology and enhances the appearance of any decent HD and 4K content you throw at it – as well as looking next-level sensational with native 8K sources if you can find any.”

But there are two key niggles to be aware of. First, it doesn’t handle motion processing and HD upscaling as well as its direct Samsung rival. HD sources look slightly more artificial and less defined on the LG during our comparisons. 

Second, despite having the What Hi-Fi? Award-winning MLA tech, the Z3 was noticeably less bright than its cheaper 4K sibling. With the LG G4 set, which the company claims is even brighter than the G3,  due to come out, this makes it a hard sell unless you really want 8K.

Also consider

  • Samsung QE75QN900A: Samsung’s 2021 flagship 8K TV is available for marginally less than the Q900D at the moment. We recommend the new model over it, but if you can’t afford the extra cash it’s still a valid alternative.
  • Samsung QE75Q950TS: though stocks are more limited, the 2020 QE75Q950TS is even cheaper than the 900A and D, making it one of the most affordable 8K options you can get at the moment.
  • Sony KD-75ZH8: Sony has a dedicated following in the world of TV. If you fit that bill then, while stocks are limited, if you can find one and really want an 8K set from Sony, the KD-75ZH8 is the only option at the moment.

How we choose

You can now buy 8K TVs from a number of brands, including Samsung, LG and Sony, though due to their niche appeal, there are comparatively far fewer models to choose from. But as an 8K TV is a huge investment in money and space what factors should you be considering when trying to choose? 

If you've got 8K on your mind then picture quality is obviously a high priority so it's important to carefully consider the type of display technology being used. 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 colours. 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.

For the time being, most of the content you watch on an 8K screen is going to be 4K, so how well the TV upscales should be one of the biggest factors in choosing which model is right for you. A great 8K TV should show make lower resolutions look their very best, with processing that enhances and sharpens the picture without making it appear processed. 

Are you planning to combine your huge new TV with a dedicated sound system? You probably should, because even high-end TVs have sound that's passable at best. 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 having incredible picture quality if the accompanying sound is rubbish.

How we test

We use the same testing methodology reviewing 8K TVs as any other set. At its heart the process involves comparative testing in our controlled viewing room. 

We never make performance comparisons based on our testers' memory. That’s why we always make sure to test the TV we are reviewing directly against its rivals and other products we think the reader would be considering in our viewing rooms. The TVs are set up directly next to one another, connected to our reference AVR and 4K Blu ray player, which we use to split the signal when running test discs.

The test discs we use are an ever evolving library of 4K Blu rays that we update to reflect what people are currently watching. We also tailor the discs to test specific aspects of the TV’s picture performance. For example, we would use an incredibly dark scene from a movie mastered at a low nit count, such as The Batman to check shadow detail. For audio, we use a demanding bassy scene, such as the spice collection scene in Dune, to gauge low end audio performance. 

On 8K TVs we also make sure to use any test content shot at that resolution – though at the moment this is generally limited to test footage provided by the TV makers, rather than actual movies or TV shows. This is why we rank upscaling as such an important factor for 8K TVs – pretty much everything you watch will be 4K or 1080p.

From there we check app support by running through a checklist of services we think most buyers will expect. We then install them and check if they run in the resolutions, HDR and surround sound audio formats they should on the TV. For gaming performance, we do the same process with an Xbox Series X console connected. During these checks, we also measure input lag.

Before making any final conclusions we also ensure at least two testers have run the checks and have compared notes. Our reviews are never based on one tester’s experience with the product in isolation

FAQ

Does Apple TV do 8K?

No version of Apple TV currently supports 8K video streaming. The latest Apple TV 4K we reviewed launched in 2022 and as the name suggests, capped at UHD streaming quality. There are some rumours that the next version of the Apple TV will feature an updated chipset and be able to support 8K, but we’re taking all of these with a hefty dose of salt. There is currently next to no content even shot in 8K, let alone available to stream. Even if the new Apple TV does arrive and does theoretically support it, you would still not have much, if any, content to watch in native 8K.

What is the cheapest 8K TV?

8K TVs are still a rare, and generally premium item. But they are gradually coming down in price. This year we expect that to continue, with the launch of new Mini LED 8K TVs, such as the LG QNED99T – though we await final pricing to confirm this. Despite the gradual drops in price, new 8K TVs will generally cost at least as much as a flagship OLED. That means you will need multiple thousand to spare as a baseline unless you’re willing to buy a second hand 8K TV.

Which companies make 8K TVs?

Samsung has been the main company pushing 8K TVs, though Sharp was the first to show one off when it showed a demonstration set at the Consumer Electronics Show (CES) in 2013. In the current market, Samsung and LG are the biggest names with 8K TVs you can buy, although TCL also offers an 8K Mini LED, the X925, in select markets. 8K projectors are far more common and can be bought in most specialist home cinema retailers. Though again, be warned: these are also very expensive and suffer from the same shortage of native 8K content as TVs.

What is 8K?

What we're talking about here is resolution. This means the number of horizontal and vertical pixels. Pixels equal information, so more pixels should mean a better quality image. That's the theory, at least.

In the case of 8K, this means a horizontal resolution of 7680 pixels and a vertical resolution of 4320 pixels (7680 x 4320), resulting in a display that consists of just under 33 million pixels.

By comparison, 4K video has half the number of horizontal lines and half the number of vertical lines (3840 x 2160), equating to a total pixel count of around 8.3 million.

So, yes, 8K has four times as many pixels as 4K (and 16 times the number of Full HD, for what it's worth).

Who is making 8K content?

8K video developments to date have largely been driven by filmmakers and TV broadcasters. From a video-editing point of view, the higher resolution can be useful. While filmmakers may not ultimately deliver an 8K film, shooting in the higher resolution gives editors room to manoeuvre, allowing for cropping and zooming while still retaining a high-resolution image. That said, 6K cameras are currently far more prevalent in Hollywood.

Meanwhile, in Japan, broadcasters have been experimenting with 8K TV for some time. Back in 2015 the Japanese Broadcasting Corporation, NHK, ran a series of 8K trials, and in 2016 the company announced it was successfully demoing 8K broadcasts. So successful were the trials, NHK has now launched the world's first 8K television channel. Since 1st December 2018, it has broadcast 8K TV shows on a daily basis, 12 hours a day, and even broadcast the 2019 Rugby World Cup in 8K. Next up is the Tokyo Olympics, which is now scheduled to take place in the summer of 2021.

The Korean Broadcasting Corporation (KBS) is also researching 8K broadcasts, working with LG on content, possible broadcasts and displays – there was 8K experimentation at the 2018 PyeongChang Winter Olympics. And if you were in Brazil at the time, you could have watched the 2018 World Cup in 8K.

The likes of Netflix and YouTube were, of course, quick out of the blocks when it came to 4K content, and now streaming site Vimeo has jumped aboard with 8K. A recent update adds support for HDR and 8K resolution videos. Naturally, you will need an 8K screen to take advantage, and you might be hard-pushed to find anything truly worth watching.

Rakuten TV wants to become a true global alternative to Amazon Video and Netflix and has ambitious plans to help that become a reality. Along with a rapid expansion into new countries, it seems 8K content is also part of the strategy - the company announced plans to have 8K films on its service by the end of 2019, although all has since gone rather quiet on that front.

So ultimately, despite many companies expressing optimism about 8K, it's important to be aware that almost no native 8K content is available. If you buy an 8K TV and want to show off it's ridiculously high resolution. At this stage, no streaming services have even hinted at launching 8K content, and it seems increasingly unlikely that an 8K disc format will ever materialise.

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