Review: Apple 4K TV

C we are (better late than never) to talk a little about Apple TV 4K, a set top box Launched by the company in September 2017 and finally, as the name implies, brings a much-awaited new feature: support for both 4K content (38402160 pixels resolution) as well as HDR10 (High dynamic range, or Large Dynamic Range).

Before embarking on these two big new features of the new model, however, let's go through the most subtle changes. But here is a warning: Apple TV 4K is a very specific and timely upgrade of the fourth generation Apple TV. This has changed a lot compared to its predecessor, bringing news such as a new operating system (tvOS), an app store (App Store), a new remote control (Apple TV Remote), etc.

If you haven't read our fourth-generation Apple TV review, published in late 2015, I suggest you do so to get a better understanding of this article.

Let's go?

Visual and technical specifications

On the outside, we have basically the same black box 35mm high, 98mm wide, 98mm thick and 425g. What changes is that we now have a circular air inlet / outlet at the base of the device, which serves to cool the Apple TV. The simple reason for this: the replacement of the A8 processor for a A10X Fusion, designed to handle all of this great 4K / HDR image processing).

At the rear we have an HDMI 2.0 (instead of 1.4), a Gigabit Ethernet (instead of a 10 / 100BASE-T Ethernet) and the input for the power cable. Here's my first warning: Since Apple TV doesn't come with an HDMI cable in the box, make sure you buy one that is 2.0, 4K / HDR10 compatible. It's no use having the Apple TV 4K, a high-end TV and a low quality cable. 😉

But back to port availability, a noticeable absence of USB-C is used for services and support (yes, she's no longer reading everything now done wirelessly including connecting to Xcode to capture screenshots and making video recordings, besides running tools). diagnostic).

In terms of connectivity, there are two new features: Bluetooth 4.0 and 5.0; In addition, Apple TV 4K has 802.11ac Wi-Fi with MIMO (like fourth-generation Apple TV). The difference is that in 4K the two frequencies (2.4GHz and 5GHz) work simultaneously. In addition, there is still the infrared receiver and the sound output surround Dolby Digital Plus at 7.1.

Remote Control

The remote remains the same. Not to say that it looks exactly the same, the “Menu” button has a raised white outline to solve a critical issue in our fourth-generation Apple TV review: as the buttons are centered vertically, it was a bit difficult Without looking, I know where the control is pointing. Now, with this outline, you can distinguish.

No more, it keeps its prs (volume buttons working perfectly to control the TV sound; you don't need to point the control at Apple TV for it to work; when you turn on the Apple TV, the connected TV even selects the input hers, if you changed it the last time you used the TV) and cons (still made of glass, so if you drop it, you have a good chance of breaking it).

A very correct decision from Apple is that it hasn't changed, since the control is still pretty much the same as requiring the user to physically squeeze the touch surface to serve as a button. The company could do as it does on trackpads, where you simply touch the glass surface to simulate a click and take action. This, however, would greatly impair navigation, with accidental touches happening all the time.

IOS app

Didn't get used to the remote control or is it lost around the house? No problem! Apple has created an app so that owners of iPhones and iPads can control their set top box directly from your gadgets.

The idea here is to take everything you can do on the remote control and put it inside your iDevice. In fact, the experience goes a little further, since on iPhone / iPad you can type passwords or search in a much simpler way by typing on the virtual keyboard instead of picking up letters on your TV screen with the physical control.

It's worth noting, though, that you don't need to have the Apple TV Remote app on your iPhone / iPad to take advantage of it: if you're using physical control and you come across a form (and you have your iPhone / iPad on the same Wi-Fi network). -Fi is right next to you), a notification will appear on your device for you to enter the password or type in the name of the movie you are looking for on the device, as it is much easier there.

Another alternative on iOS 11 is to add an Apple TV widget to the Control Center itself. It is a bit more limited than the standalone app, but it gives you the expense in most cases.

No crab yet

Because . Much of the tvOS interface and the way we interact with content was thought to be used by Siri. Things like fetching a content from catalogs of services like iTunes Store, Netflix and / or HBO GO, playing a certain song on Apple Music, finding movies / series starring a particular actor, skipping / skipping the watched content, among many other things if make it more enjoyable interacting with the virtual assistant instead of simply pushing buttons.

This, however, is still a distant reality from ours. There is no sign of the arrival of Siri in Portuguese on Apple TV, so we can only wait and warn that without it, all the experience with the fourth generation Apple TV and Apple TV 4K, yes, is greatly impaired.


Just like in the past release, Apple decided to offer two different capacities: 32GB and 64GB. I honestly see no reason to buy the 64GB model.

Unfortunately there is no simple / practical way to control how many mega / gigabytes you are already consuming from storage. But the truth is that even installing multiple applications doesn't seem like a problem. Unless money is left over, opt for 32GB for good!

tvOS and App Store

In the fourth generation Apple TV review, we said that tvOS has great potential ahead. This has not yet been explored, but having an operating system like tvOS available, being the foundation of set top box, something very positive. Mainly by the arrival of an App Store and the passing of Apple application control to developers / companies.

Unfortunately we still ran into each content provider's strategy; If on the one hand we have HBO GO available to those who are not subscribers to a cable TV plan, it seems that we are still far from seeing a Premiere (football) available in the same way, for example. The app is now available for tvOS, but users must necessarily have the service contracted / tied to a TV plan. This, however, is not up to Apple and we cannot blame it for that.

Already the other points of tvOS go through the hand of Ma. As we mentioned above, lacking greater transparency in the storage of the device and what we are using, and a way to better control application updates (today, or you put to update all of automatically or does not update anything, since there is no way to do individual application updates).

From tvOS 10 to 11 we had good improvements, too, such as the automatic switching of light and dark themes according to the time of day, iCloud home screen sync (if you have two or more recent Apple TVs in your home) and the suitability is also automatic for playback to match that native to the content being displayed, both in terms of frequency and HDR mode.

4K / HDR

Then we come to the main point of Apple TV 4K: content support with 38402160 pixel resolution, as well as HDR10 and Dolby Vision support.

Difference between a 4K TV and a 4K / HDR

We have nothing less than 4x the number of pixels over the previous one. And more pixel density means more image clarity in practice. J HDR / Dolby Vision feature gives you more vivid, deeper and more immersive color images.

According to the site Open at dawn, the HDR10 was one of the first HDR formats, with a wide color gamut setting (Rec.2020) and 10 color bits. It is an open format and is supported by various companies like Samsung, LG, Dell, Sharp, Sony, etc. The biggest "problem" of the HDR10, however, is that it defines a range of static brightness that stays fixed throughout all scenes of the content regardless of whether you have one scene last night followed by another in the middle of a blazing sun desert.

Dolby Vision has no such problem, allowing a content to have that dynamic range of scene-to-scene brightness as well as 12 bits of color and a maximum brightness of 10,000 nits (which in practice are reduced to 4,000 nits). The problem, in this case, is that TV makers have to pay a Dolby license, which brands like LG, TCL and Vizio do, but others don't.

Precisely because of this, the HDR10 + format was born but this is another point, since the point here explains the technologies present in Apple TV 4K.

Obviously, to enjoy it all is no use having only one Apple TV 4K. If you connect to set top box from Apple on any old television, having absolutely nothing like that. I need to have a 4K TV that also supports HDR10 content. In addition, to do streaming 4K content (Netflix, iTunes Store, etc.) will require at least 25Mbps connection.

And what about the experience of watching a series or a 4K / HDR10 movie on Apple TV 4K? Just what you think! The resolution is much better and the colors are much more vivid, obviously. Everything, everything is more beautiful and pleasant. But that also varies from television to television, even though they are all 4K / HDR10. There are TVs with LCD panels, other OLEDs all with intrinsic variations in the technologies used. So, there is no way I can say here that you will have an “XYZ” experience because it all depends on the TV model you have or plan to buy.

Incidentally, here is an obvious warning, but it is worth remembering: If you do not have a 4K / HDR television and do not want to buy one so early, Apple TV 4K is definitely not for you. Save and go without fear of the fourth generation.

In addition to all this, remember that to enjoy 4K resolution and HDR you need 4K / HDR content! There is "quite" something in the iTunes Store and Netflix, but obviously the very limited collection and more restricted to releases. This is something that tends to evolve well over time, of course.


We do not have Siri, but soon it seems that we received the TV app, as we reported here.

If it changes the way we interact with Apple TV, I can't say, but it's still nice to see that things are slowly evolving for us. For now, the app is only available in Germany, Australia, Canada, the United States, France, Norway, Sweden and the United Kingdom.


My experience with the product has shown that, from a technical specification point of view, there is nothing to complain about. The A10X processor gives the message and everything in tvOS 11 flows very well you hardly have any problem in this regard.

A fact here that I must point out is that I am not a very adept at games, so I have not thoroughly tested the capabilities of this view. Still, the A10X has the potential for brilliant things given what it does on iPhones and iPads, so I wouldn't say that's cause for concern. Also, if you are a gaming person, you will not trade your console or your gamer PC for an Apple TV. This would be impossible not because of the capacity of Apple TV itself, but because of the game catalog currently available on the App Store that does not go anywhere near specific game platforms.

The problem with today's Apple TV, at least as the ecosystem is today, is that it becomes a set top box luxury for you to use Netflix or similar services. That's a problem, as there are much cheaper, more affordable solutions on the market (from Chromecast to smart TVs with the Netflix app already installed).

Speaking of my use itself, I have some apps that are pretty cool to use on Apple TV and that “justify” me having one at home:

Plex app icon: Movies, TV, Music + more

It makes it a lot easier to watch videos I have on my Mac.

VLC for Mobile app icon


World Surf League app icon

For those who like surfing and accompanying the world championship, the obligatory app.

Globoplay app icon

PlayKids app icon: Learn Playing

Required if you have children. 😜

YouTube app icon

The videos of They are beautiful on TV!

TED app icon

Great for anyone who wants to be distracted by something fast and at the same time educational.

Horizon Chase - World Tour app icon

How about doing exercises in the living room with TV instruction?

Besides, of course, the obligatory trade

Netflix app icon

HBO GO ® app icon

Amazon Prime Video app icon

Are apps I can't live without? No, but they undoubtedly enrich my experience with set top box. In practice, that's what differentiates the use of Apple TV 4K (which is in my living room) from third generation Apple TV (which is in my bedroom), yes, it has become a mere “Netflix / HBO GO / Amazon Prime Video player. ", for me).

But how do you know if you're going to use an Apple TV beyond trade? Just testing, really. The good news is that if you buy one and don't like it, you have up to 14 days to return; What's more, if you only find out that you really didn't like the product or that it's not worth the investment, MM Frum's Classifieds are up for you to sell your Apple TV with as little loss as possible (fortunately, the well-heated used market in for Apple products).
