Review: Updated: Chromecast


Update: Chromecast is getting a $15 ethernet adapter!

Chromecast, pure and simple, is an inexpensive media streaming adapter that turns any HDMI-equipped television into an app-driven smart TV when paired with a phone, tablet or computer.

The diminutive package is Google’s answer to products like Apple TV, Roku 3 and the Amazon Fire TV – all of which are designed to take your digital content and streaming services like Netflix, Sling TV and Amazon Prime Instant Video and get them up on your big screen without fuss or fiddle.

But whereas the competition uses fancy interfaces to hold content and run on complex operating systems, Google’s little streamer is content just sitting there and waiting for your other devices to tell it what to stream.

More impressive, though, is its price. From day one the Chromecast wowed with its cheap price and it can now be had for as little as $32. It’s similarly bargainous in the UK: just £30 – less than a third of the Apple TV’s RRP.

On launch, the services that tied in with Chromecast were limited and very much a work in progress. But 15 months on, the list of compatible apps is impressive.

Most of the big hitting services are now compatible, with Netflix, YouTube, Vimeo, Hulu Plus, Pandora, HBO Go, Starz and Showtime Anytime etc… all ready and waiting in the US, and BT Sport, BBC iPlayer and more in the UK. You can find a complete list of Chromecast-compatible apps on the Google Chrome Store.

Music is really restricted for UK users, with even the lone Pandora app support no good for us due to licensing restrictions. The key addition here would be Spotify, but there’s a wide range of services that could become available. The truth is that the ‘casting’ method of getting video onto your TV is simply not very compatible with music.

We’re sure that this will change (Google can be very persuasive…), but there are major limitations on built-in support at the moment.

Google’s Chrome browser on Mac or PC lets you mirror a browser tab to your TV, meaning that you can theoretically send any of these services to your TV that way, but there are issues with this.

If you stream video via the compatible apps, the content is streamed directly from the internet to Chromecast without traveling via your phone or tablet.

But if you mirror a browser tab, you’re effectively streaming video to your computer from the internet via your router, then streaming it back to your router and then streaming it out once more to your TV, resulting in heavy network traffic.

If your network is flaky, this will result in choppy performance. We tested on a variety of networks and found results were variable but a clear network (around 8-10Mbps down) should be able to handle it. Browser streaming options are Extreme (720 high bitrate), High (720p) and Standard (480p).

Using Chromecast, though, it’s clear that it’s designed for use with portable devices in mind. You won’t find a Chromecast remote in the box or a main menu tying all of the apps together like on an Apple TV or Roku 3. Recent firmware updates have soothed this problem giving users the ability to use their TV remote to control some functionality, but at the end of the day you’ll still need to keep a device running the app within arm’s reach.

Chromecast rivals

All streams originate from a special “Cast” button that’s built into each compatible mobile app – your device is the remote.

Currently, Windows Phone 8 users, who don’t have many options among app-filled streaming technology, are totally out in the cold for Chromecast support, with only third party YouTube app TubeCast being compatible. So Chromecast is only really suited to those with Android and iOS devices.

Despite these limitations from the big names, Chromecast has extra potential to it thanks to developers getting creative with the Google Cast SDK.

Apps like AllCast enable Android and Apple iOS users to display video and photos through the Chromecast. Which is useful since Google somehow neglected to add this feature to Android.

Both major media center apps, VLC and the Plex app will happily stream to Chromecast, which is perhaps the best way to get your library of downloaded videos up on the big screen. Photo Caster is a free app that enables iOS users to put their photos on-screen similarly.

Media Browser is an app for iOS and Android that streams media content stored on any computer in the house, giving the Chromecast home theater PC (HTPC) granting capabilities. You can even stream Podcasts from a few apps.

The way Apple integrated its AirPlay streaming solution deep into iOS means that it inevitably has better support when combining an iOS device with an Apple TV, but as long as developers continue to use the Cast SDK, we will inevitably see almost as widespread support for cross-platform solutions – iOS, Android and Chromecast all working together seamlessly.

Sure, Roku has its Roku SDK, but it’s easier for many developers to make their apps compatible with the Android-based Chromecast. It requires a little bit of retooling rather than learning an entirely new ecosystem, as is the case with the Roku.

Between its universal nature, rock-bottom price and ease of setup, Chromecast is massively tempting as a little TV add-on.

Design and interface

Chromecast is so small it could easily be mistaken for an oversized USB thumb drive with a little more heft to it.

That contrasts with Apple TV or Roku 3, which sit as separate boxes, and often have extra outputs, such as for audio. It looks more similar to the Roku Streaming Stick, but don’t be fooled – the stick doesn’t use casting, it runs apps onboard like the other Roku devices.

Chromecast just is one big HDMI plug, with the exception of its power cable.

It’s a simple black unit, likely to blend into the colour of most TVs (though if it ends up sticking out of the side noticeable, it’ll be somewhat more intrusive).

If your TV is wall-mounted, Chromecast could be really awkward to implement depending on your TV’s HDMI port positions. It might also not fit into the space for HDMI ports in some setups, so Google has included a short HDMI extender cable.

It gets around immediate problems, but be aware that at 72 x 35 x 12 mm, Chromecast might be an awkward fit.

Powering Chromecast can be a little more complicated depending on the age of your television, because it can’t run on the power from the HDMI port alone.

On the rear of the unit is a micro-USB port, and Google has included a five-foot micro-USB-to-USB cable in the Chromecast box along with a power adapter that plugs into the mains.

Ideally, you wouldn’t use the latter of these – if your TV has a USB port on it, as many Smart TVs do, you can use that as the power source.

Otherwise, you’ll have to plug in, and it’s possible you’ll find that five feet isn’t enough. Again, it’s not a big problem, but it’s worth being aware of.

Once it’s plugged in and ready, Chromecast’s software setup is not complicated at all – in fact, it’s barely existent.

set up

It’s a matter of visiting Google’s Chromecast “getting started” website on a laptop, tablet or smartphone, downloading and installing some software, and connecting the device to your home WiFi network.

Google has provided apps for each platform that take care of this for you, with the Android version especially good – it does almost everything for you.

set up chromecast

On iOS, for example, you need to switch to a Wi-Fi network created by the Chromecast so that you can then tell it how to join your main Wi-Fi network – it’s easy enough, but requires a bit of annoying back-and-forth to the settings.

On Android, it’s all handled for you invisibly – you don’t need to manually change Wi-Fi at all. It’s impressive.


Once you’ve set up, Chromecast is basically ready to go. It’s always on, so when you want to use it, just switch the HDMI input you’ve got it on and fire media at it. When there’s nothing playing, you generally just get a screensaver, showing pretty photography.

Content and performance

Chromecast finally gives Android owners an official media-relay option that broadcasts content from their smartphones and tablets to a TV in similar way to Apple’s AirPlay technology. That it works across Android, iOS, PC and Mac is even better.

There’s a “Cast” button that’s usually built into the top right of all of the compatible mobile apps – it looks like a rectangle with broadcasting bars (like a Wi-Fi symbol) in the corner.


It’s easy to recognise, despite Android being full of similar rectangles these days (and Apple’s AirPlay symbol being somewhat similar).

Tap the “Cast” button and you’ll be offered a list of Chromecast devices on your network, so just choose which one and you’ll see the screen spring into life, loading the video or audio content you selected.

The app then becomes a remote, basically, enabling you to control the screen. The likes of Netflix even give you a custom screen on the device, ditching playing the video there as well in favour of big buttons for controlling playback easily.


Video quality is great from most online sources – Netflix in HD looks as good as you’d hope. We did encounter some freezing issues towards the end of a film, but pausing and restarting got us back in action.

Netflix is also capable of streaming from the website on PC or Mac natively (not using the tab mirroring feature) to Chromecast, but when we tried this, the audio was often a tiny bit out of sync.

Not enough to make it unwatchable, but it was a bit distracting. Most of the time, when you send video over to the Chromecast, it picks up quickly. Generally, once you’ve started playing a video, you can exit the app and start doing other things – and this applies both to mobile and desktop.

This means Chromecast can act as a second screen in a couple of cases, particularly when used with desktops or Android devices, letting you browse the internet or do something else on the computer while a tab with your Gmail, Twitter feed or a video is running in a “casted” background on the big screen. Google also announced at its developer conference that it would release new software that would enable Android phones and tablets to work as controllers for some Chromecast games.


However, it’s not suitable as a second screen option for work; it’s just a mirror of something you’ve already got open, so if you want to interact with it, it needs to be done on your main computers screen. There’s also noticeable two-second lag between the computer and the TV.

That’s a similar amount of consistent lag experienced when using Apple AirPlay mirroring on a Mac computer, but it is at least consistent – it doesn’t suddenly hang or get choppy, for the most part.
But here’s where AirPlay mirroring from a Mac shows up Chromecast’s limitations: the browser extension is just that – browser-based.


Showing off a photo you retouched in Photoshop, a document you want a group to proofread in Word, or any program outside of the Chrome browser tab you’re casting requires diving deeper into an options menu for a hidden command that’s deemed “experimental” by Google.

It’s buggy and slower than Apple TV’s full computer mirroring. Chromecast is not meant for mirroring system-wide applications -at least not yet.

App limitations

The Chromecast tab extension is also limited to Chrome at the moment and may never work outside of the Google-owned browser. That means FireFox, Internet Explorer, Safari and Opera users are out of luck if they had hoped to “Cast” using their favorite browser.

While Google has opened up the Chromecast API for building applications, it’s still forcing everyone to use Chrome for tab casting from a computer.

Chromecast HDMI media streaming device

Chromecast also doesn’t require an entire Apple TV device to sit in your entertainment console or force you to wire up with a lengthy power, HDMI and optional Ethernet cable.

Its plug-and-play nature means that it can be transported much more easily and fit into a backpack to carry to a school presentation or business meeting (we used Apple’s iCloud version of Keynote to show a presentation from a Chrome tab), hotel room, or friend’s TV. That flexibility may be worth its inexpensive price alone.

There is one potential of inflexibility, though. The total lack of built-in apps or direct method of control (such as a dedicated remote) means that if your device runs out of battery or is in another room, you can’t play anything.

We had a few little niggles, such as a photo-casting app that forgot the Chromecast after each use and had to hard quit and restarted.

Most of these are probably up to developers to fix, though, and as things mature, we expect they’ll improve.


Google’s take on an AirPlay like universal streaming service is hugely impressive, not just for its price, but because it works well, on many platforms.

It’s possibly the perfect companion device to an older TV with no smart features, and it’s certainly the cheapest way to get Netflix up and running in your living room if you can’t plug in any other compatible devices.

We hope that developers will also be able to work in some other interesting Chromecast options for the future, provided the technology allows it – something equivalent to the big-screen gaming that AirPlay enables for Apple users would be great to have cross-platform, for example.

That said, this option is now being covered in Google’s forthcoming Nexus Player, so don’t expect Google Chromecast to get gaming features any time soon.

We liked

Chromecast is brilliantly easy to set up, gave us little hassle after the first few minutes, and then worked really well.

You quickly become accustomed to the idea of just reaching for your phone and beaming something over to it – just like the future should be.

The streaming quality is generally very good, and it’s quite reliable, especially for a product that’s still fairly early in its life. It’s also impressive that it works so well on all platforms.

At $30/£30, we definitely like the price. It’s well into impulse-buy territory, and we do think it’s worth picking one up just for its potential, even if you already have a way to stream the services it currently works with.

We disliked

The lack of apps was the simple, major problem when Chromecast originally launched. It was fairly well-supported in the US, but elsewhere it needed fleshing out… and it has been.

The only thing you might dislike about Chromecast is its reliance on the phone in your pocket or the tablet on your coffee table. But for anyone who keeps those things with them, it’s not a problem and in fact for many it’s a more convenient way of arranging things.

There are a few other things we’d like to see, such as a bit more polish to improve things further – faster loading of videos in some apps, broader support in basic Android apps, stronger streaming from desktops, for example.


Chromecast is an inexpensive, easy-to-use way of accessing streaming on your TV. All the major video streaming apps are compatible and you soon find yourself using it on a daily basis.

If it cost more, we’d say it might be worth looking at the Amazon Fire TV or the Nexus Player, but at this price how can you possibly argue? Chromecast is fun enough, robust enough and has enough potential that thoroughly recommend it to anyone without a smart TV.
