Since we initially published this review, Google has come up with the Google Home range of “smart speakers” – modular devices that can take commands from you wherever you are nearby, and control things like smart home lighting, music playback… And, of course, Chromecast. If you have a Google Home device on your network, you can ask your Chromecast to play movies, TV shows or music just by speaking to it! We updated this review in October 2017.
The Chromecast Ultra difference
While it looks almost identical to the second-generation Chromecast – the “puck” design was introduced to make Wi-Fi performance more reliable – inside the Ultra is a much faster CPU. The video hardware has also been upgraded, giving the tiny device the grunt to stream and decode 4K video content without raising a sweat. All of this comes at a cost, though – the Ultra needs a lot more power to run than its predecessors. As a result, this is the first Chromecast you can’t power from a spare USB port on your TV. Instead, you have to use the supplied plugpack – which has a few smarts of its own.
|Wired Network (Ethernet) Support|
Streaming 4K over Wi-Fi can be fickle – for some, it’ll work just fine, but if you’re in an area with a lot of congestion, or your Wi-Fi modem/router is a few rooms away, smooth streaming could be a challenge. Google’s built a clever option to help solve this in the plugpack power supply. There’s a full-size Ethernet port on its back – and if you plug a standard Ethernet cable from it to your modem/router, you’ll have a hard-wired streaming device that’s totally immune to Wi-Fi issues.
The Wi-Fi support on the Ultra is nothing to be sneezed at, too – we ran wireless, connected to an Asus router hidden away in a cupboard, with the Chromecast tucked away behind both an amp and the screen. It still managed to lock onto 5 GHz Wi-Fi at 300 Mbps – three times the top speed of the NBN. It’s easily one of the most impressive Wi-Fi devices we’ve ever seen.
|Support for the Latest 4K Video Format|
A big upgrade is the Ultra’s support for the new H.265 video standard, also known as HEVC. This allows 4K streaming at a fraction of the data rate it would normally require. It’s pretty cutting-edge tech as far as video streaming goes. So far Netflix is the most prominent company to start using it. What this means is that with the Ultra you’ll be able to stream 4K content reliably on much slower broadband connections. As it takes the data rate requirement down to around 15 Mbit/sec, you’ll very likely get great 4K streaming even on a 25/5 NBN connection. Very few devices support HEVC, but the Ultra is ready for it.
Chromecast devices rely on you having a smartphone
or tablet running either Android or iOS to function. Once you’ve plugged the device into your TV (or AV receiver if you prefer) you need to download the free Google Home app from your app store. The app will alert you that a new Chromecast was found and start walking you through the process of giving it a name and setting it up. Google’s been refining this process over the years, and it’s now incredibly smooth and user-friendly – it now even provides sample videos to play from inside the app to test your new device, with tips overlaid on the picture.
By the time you’ve gone through the setup process, your new Chromecast
is ready to go – what you do from that point is entirely up to you. The Google Home app provides links to a huge range of apps that support Chromecast, but you likely have quite a few installed on your device already. All you need to do is tap the Chromecast icon in the app you’re using – it’s almost always at the top right corner of the screen – then choose your device as the destination. From that point, whatever you play in the app gets sent to your TV instead – in full HD or, with the Ultra, 4K if the service and your connection support it.
When not playing anything, Chromecast’s default display is a slideshow of photos and artworks, overlaid with the current time and temperature – virtual wallpaper you can personalise. You can have it bring up Facebook content, photos from your Google Photos library, news headlines and more – all configurable from the Google Home app – and the Chromecast remembers your preferences.
Oh, and one other thing – the Chromecast “puck” as well as its HDMI plug are magnetic. You can plug it into your TV and let it attach itself to the back, rather than dangling on its HDMI ribbon. And when you want to take the device over to a friend’s place for some streaming, the HDMI plug happily glues itself to the body of the Chromecast so it doesn’t get damaged. It’s a simple design tweak, but a very useful one.
Well, it’s not really
something you’d want to enable at parties, but the new Guest Mode on Chromecast is an incredibly handy thing. Enabled by default (it can easily be turned off in the Google Home app), Guest Mode assigns a random 4-digit PIN to your Chromecast, and displays it on the screen when no video is playing. Anyone with a Chromecast-capable app can then connect to your Chromecast directly (without needing access to your Wi-Fi network) and play stuff on it. A very handy feature for gatherings of family and friends, and it’s also immune to strangers hijacking your Chromecast – you can’t play anything as a guest unless you know the PIN, and the only way to see the PIN is to be in the room looking at the screen.
The one thing that may stand out to prospective Chromecast Ultra buyers is the price. At $99 it’s a long way from the impulse-buy original Chromecast model. Part of this can be blamed on the exchange rate – we actually pay around the same as US customers do for the Ultra, and the current “standard” Chromecast now sits at $59. For the extra money you get 4K capability, faster performance overall across all content, and the Ethernet-capable power adapter that’s only included with the Ultra (it can no longer be purchased separately for older models, but a similar adapter used to add another $20 to the price).
Aside from the Ultra’s undeniably improved performance, you’re buying yourself a bit of future-proofing with this one. It’s a device that can handle the latest 4K formats and send them to any capable TV, regardless of whether or not their built-in apps are up to the task. You can save yourself $40 by opting for the standard Chromecast, but you won’t be able to stream 4K, you won’t get the Ethernet connectivity and you’ll have a very slightly longer wait for streams to start up. With the Ethernet support a hugely valuable addition, and the device’s overall snappy performance and format support, the Ultra feels like the right choice. It’s a device that’s already ready for the stuff you’ll be streaming in the future.
