Apple TV 4K (2021) review

Our Verdict

It’s not worth upgrading if you have the previous model, but if you’re simply looking for the best video streamer out there, this is it



Over four years since the launch of its predecessor, there’s now a new Apple TV 4K. Not that that’s obvious from the design, because nothing has changed on that front – and you’d have to examine the specs of both models quite closely to spot any differences there, too. There is a new remote control, though you can buy one of those to go with the last-gen model if you really want.

In other words, it’s hard to get too excited about the new Apple TV 4K. It’s more of a shuffle forward than a giant leap.

But the original Apple TV 4K was the best video streamer when it launched and, through regular updates, it remained there through its lifespan. This second-generation model doesn’t break the mould, mainly because it didn’t need to.

Instead, Apple has performed a nip here and a tuck there and produced an Apple TV 4K that’s ready for the next four years. It may not be overwhelmingly exciting, but this is the best made just that little bit better.


The new Apple TV 4K (2021) costs £169 ($179, AU$249) with 32GB of built-in storage, and £189 ($199, $279) if you want the version with 64GB. If you’re expecting to primarily stream movies and TV shows, 32GB should be plenty, but those planning to do lots of gaming should probably consider spending the extra on the 64GB model.

If you can live without 4K, the Apple TV HD 32GB is available for £139 ($149, AU$209).

All versions of the Apple TV are significantly more expensive than rival streaming devices. The dongle-like Google Chromecast with Google TV is £60 ($50, AU$99), while the Amazon Fire TV Stick 4K costs £50 ($50, AU$99). Even the Amazon Fire TV Cube undercuts the Apple TV, coming in at £110 ($120).


The new Apple TV 4K is almost identical to its predecessor in terms of design. It’s always a shame when a company chooses not to make aesthetic changes when launching a new version of an existing product, particularly one that’s been around for years, but there’s nothing wrong with the looks or build of the latest Apple TV 4K.

Dimensions (hwd) 3.5 x 10 x 10cm (1.4 x 4 x 4in)

It’s obviously bigger than stick- and dongle-style video streamers but, at 3.5cm (1.4in) tall and 10cm (4in) square, it’s compact enough to fit into almost any space. The remote control’s Bluetooth 5.0 functionality means you don’t need to place the box within sight of your seating position.

While the streamer looks and feels the same as before, the remote is new and much improved. While still compact and minimalist compared with a typical TV remote, it’s a bit bigger and significantly more solid and substantial than its predecessor, and boasts a couple of extra buttons: a dedicated mute button, and a power button that can also operate your TV and home cinema kit. The Siri button, meanwhile, has been moved from the face to the right side for consistency with modern iPhones.

Perhaps the most important change, though, is that the ‘hidden’ trackpad of the old remote has been replaced by a circular clickpad that’s reminiscent of the iPod wheel. The central button and the ring around are both clickable and touch-sensitive, so you’re able to swipe or click as you prefer, and you can also rotate your thumb around the edge to scroll through videos. It’s a much more satisfying and less finicky method of operation than before, although it’s still a bit too easy to accidentally swipe when you want to click.

However, if you own the existing Apple TV 4K and fancy that flashy new remote, you can buy it separately for £55 ($59, AU$79).


The other significant upgrade for the new Apple TV 4K is the processor: Apple has swapped the A10X Fusion chip of the old model for the A12 Bionic. The company claims that this change results in “more realistic games, more lifelike videos, and more immersive sound”. Combined with the new remote, it certainly produces a snappier user experience. The old model is still slick in use, but there’s an extra degree of fluidity to navigation on the new one and menus populate quicker.

The processor also combines with a new HDMI 2.1 socket to add support for 4K HDR content in frame rates of up to 60fps, whereas the old model was limited to 30fps when playing 4K HDR. However, there’s currently little content available in this High Frame Rate 4K HDR. Apple points us in the direction of the ‘Enhanced 4K HDR’ videos on the Red Bull TV app, but these actually look worse on the new Apple TV 4K than they do on the old model, thanks to blown-out colours and over-brightened highlights.

We suspect this is more down to Red Bull’s implementation than the technology, and the added support for High Frame Rate 4K HDR could be beneficial once more apps adopt it. We’d love to see it added to BT Sport in the UK, for example.

It’s also worth noting that HDMI 2.1 is capable of handling even more data-heavy signals than 4K HDR at 60fps, and there’s potentially headroom here for Apple to add support for 120fps 4K or even 60fps 8K in the future, although an apparent lack of support for the AV1 format suggests the latter might be a long shot. It’s also worth mentioning that the new Apple TV 4K comes without a bundled HDMI cable, which feels rather tight-fisted when you consider how much more expensive it is than its rival streamers.

In terms of formats, the Apple TV 4K (like its predecessor) supports HDR in the HDR10, HLG and Dolby Vision formats. The only one missing is HDR10+, and that still doesn’t feel like much of a loss. Audio formats supported include MP3, AAC, Apple Lossless, FLAC and WAV for stereo, and surround formats up to Dolby Atmos.

Apple has added support for spatial audio via AirPods Pro and AirPods Max headphones for both Apple TV 4K boxes with the release of tvOS 15. That means you can now get a Dolby Atmos movie experience via headphones. This will be a real boon for those who don’t have a Dolby Atmos home cinema system or who listen via headphones late at night.

Of course, Dolby Atmos is now becoming more of a concern for music on top of movies, with Apple Music having recently joined Tidal in offering a chunk of its catalogue in the format. Both apps play Atmos content correctly via the Apple TV 4K.

There are plenty of other music apps available on the Apple TV 4K, of course, including Spotify and Amazon Music. UK buyers might be disappointed to discover that BBC Sounds is missing, and Deezer is absent, too, but we can’t imagine either being a deal-breaker.

On the video side, the app selection is almost flawless. Netflix, Disney+ and, of course, Apple TV+ are all present in all their 4K, Dolby Vision and Atmos glory. The very small selection of Dolby Vision content usually available on Amazon Prime Video plays in plain HDR10 via the Apple TV app, but Dolby Atmos plays as expected.

UK users get the likes of BBC iPlayer, ITV Hub, All 4, My5, Now and BT Sport. US buyers benefit from extra apps such as Paramount+, AMC+, Showtime, Starz, Epix, HBO Max, Hulu and Peacock. The Australian selection, meanwhile, includes the likes of Stan and Binge.

The Apple TV app does its best to collate content from all of your subscriptions in a personalised list of recommendations, but the continued absence of Netflix here limits its usefulness. Google has solved this persistent issue for its Chromecast with Google TV, and we’d like to see Apple follow suit. 

Apple’s own iTunes Movies remains the best way to rent and buy movies for streaming, both in terms of the size of the catalogue and the quality of the streams, but this is now also available (via the Apple TV app) on most other streamers.

While the new Apple TV 4K is certainly less gaming-focused than many predicted, Apple is certainly still making a play for the space. There are lots of games available via the Apple TV App Store for a one-off purchase, and the Apple Arcade subscription service includes access to over 180 ‘premium’ games for a flat fee of £4.99 ($4.99, AU$7.99).

Most of those ‘premium’ games are still at the fairly casual end of the overall gaming spectrum, but support for proper game controllers (including those that come with the PS5 and Xbox Series X) makes for a satisfying console-lite experience and graphics are quickly becoming more advanced. The extra power of the new Apple TV 4K could also pave the way for fancier games in the future.


The bread and butter of the Apple TV 4K’s experience is its picture quality and we’re pleased to report that the new model puts in an excellent performance. However, the outgoing model was already superb, and the improvements here are slight.

Playing Blade Runner 2049 in Dolby Vision, there’s marginally more contrast on offer. The blackest blacks are just a little bit blacker, and there’s a little extra brightness and vibrancy at the other end. The combination creates an image with slightly more impact. This extra contrast helps reinforce the already crisply defined edges, making for a slightly deeper and more three-dimensional picture. But these differences are so slight that you need a top-end TV to notice them.

The picture is otherwise the same as that of the older model, which is the best of any video streamer we’ve tested. While most stick- and dongle-style devices out there have now moved beyond the computer-like subtlety of video streamers of old, there’s still an extra degree of authenticity and nuance to the Apple TV 4K’s delivery. It’s not up there with a good 4K Blu-ray player, but it is the next best thing, producing an image with all of the punch, definition and dynamism necessary to genuinely thrill.

While it’s now possible to set the Apple TV 4K to output content in its native dynamic range and frame rate (which we heartily recommend that you do), everything will be scaled to the resolution you select in the Settings menu, which will likely be 4K. Some purists may bemoan this ‘limitation’, but the scaling has to be done somewhere in your system and the Apple TV 4K is more than up to the task, upscaling Netflix’s standard-def episodes of Bottom with impressive clarity and control. 

Again, the new model is only a bit better here than the old one, but that’s largely a testament to the level Apple had already reached.

Finally on the picture front, both versions of the Apple TV 4K have a feature called ‘Colour Balance’ which, in conjunction with your iPhone, measures your TV’s colour balance and adjusts the video signal output so that it’s more in line with ‘industry standards’. You can apply Colour Balance to standard HDR and SDR signals but not Dolby Vision as that’s, in theory at least, accurate already.

The results are broadly good, but the Colour Balance picture is unsurprisingly warm in tone, which may not suit everyone. Once you’ve been through the process you’re given a pre- and post-balance comparison, so there’s no harm in trying it to see if it’s to your tastes.


Played via a capable home cinema system, there’s a small but noticeable uptick in the new Apple TV 4K’s delivery of Blade Runner 2049’s excellent Dolby Atmos soundtrack, particularly in terms of weight, spaciousness and cohesion to the soundstage. It’s marginal, but the new model gives every effect a little more room to breathe and fill out, leaving the older model sounding just a bit narrow and beam-like by comparison.

The same is true when listening to music, whether delivered in stereo or Dolby Atmos. There’s no loss in terms of focus or directness, but just a marginal increase in spaciousness and fullness. Of course, an Apple TV is still no match for a proper bit of hi-fi kit when it comes to music, particularly in terms of rhythmic precision and detail, but the Apple TV 4K is a much more musical performer than most of its ilk.


Overall, we wouldn’t recommend buying the new Apple TV 4K if you already own the outgoing model, at least not yet. The upgrades to picture and sound performance are marginal, the new remote, lovely though it is, doesn’t transform the experience, and the faster processor only really makes its presence felt in slightly snappier navigation.

But the outgoing Apple TV 4K was already the best video streamer you could buy and the new version is the same but a bit better. That extra power could be leveraged more in the future, too, perhaps with more advanced games and video performance. In the shorter term, the High Frame Rate 4K HDR feature will likely be used by more apps, theoretically making for smoother, better-looking video streams, particularly for sport.

In short, if you’re looking to buy the best video streamer currently available, the new Apple TV 4K is it.
