How to connect Android to TV: Summary
To connect an Android phone or tablet to a TV you can use an MHL/SlimPort (via Micro-USB) or Micro-HDMI cable if supported, or wirelessly cast your screen using Miracast or Chromecast. In this article we'll look at your options for viewing your phone or tablet's screen on the TV.
How to connect Android to TV: Step-by-step guide
Tablets are perfect for individual users – lightweight with very long battery life, and with bright, sharp screens that make light work of everything from watching films to reviewing photos. Bigger crowds call for bigger screens, though: here’s how to connect your tablet to your TV without spending a fortune or drowning in a sea of cables.
Tablet owners live in a golden age of content: streaming video applications such as Netflix, Amazon Prime Instant Video and Blinkbox, catch-up services including iPlayer and Channel 4’s 4oD, and home-spun video and photographs are all begging to be shared. And, while sharing online is the ultimate convenience, sharing in person is more fun. The problem is your tablet’s screen: perfect for one or two people but it will never feel smaller with five people crowded around it. This is doubly true for smaller tablets such as the 7in Amazon Kindle Fire HD.
The good news is you probably already have a device in your living room which is perfect. Your TV is big, bright and no-one has to squint to see what’s happening on it. There’s an ever-increasing number of ways to get video and pictures onto it, from straightforwardly stringing cables around to ingenious – but often more expensive – wireless options that will propel your living room into the 21st century. Here we’ll explore both options, as well as looking at the services that will let you share your subscriptions, photos and videos on the big screen – and those that won’t.
Although we’re talking predominantly about Android tablets, the same advice applies to Android smartphones.
Connect Android to TV: HDMI
HDMI (High Definition Multimedia Interface) is the interface standard du jour. If your TV was bought in the last decade it has an HDMI port, as does almost every set-top box, games console and a decent number of still and video cameras. The benefit to HDMI, apart from its ubiquity (which means it’s cheap), is that it accommodates HD video and audio simultaneously, allowing you to connect devices without worrying about watching a film in full HD but having to make do with your tablet’s tinny speakers. An HDMI output is an advantage that many Android tablets have over Apple’s iPad.

HDMI plugs come in three sizes. Regular HDMI (or Type A, left) are the full-size ports you’ll find on devices where space isn’t an issue: think TVs, laptops and games consoles. The sockets you’re likely to find on tablets and phones will be either Type C (also known as Mini HDMI, middle) or Type D (Micro HDMI, right). Of these, Micro HDMI, or Type D, is the smallest. Whichever type of port your tablet has, connecting it to an HDMI socket isn’t going to cost you the Earth: expect to pay well under £10 (under £5 in some cases) for an HDMI to Mini- or Micro-HDMI cable.
A decent range of tablets have either HDMI or its miniaturised variants. The Acer Iconia A1, Tesco Hudl, Archos 80 Titanium and Nokia 2520 – among many, many others – all offer it. It’s the most straightforward approach.
You’re not limited to buying a tablet with an HDMI output to connect it to your TV, though.
Connect Android to TV: MHL / SlimPort
HDMI is easy to understand: it’s a port that only does one thing, after all. The drawback is that not all tablets have an HDMI output. The good news is that a pair of widely-supported standards have emerged that allow Android owners to connect to external displays using their microUSB port.
The standards in question are MHL (Mobile High Definition Link) and the newer SlimPort. Both look the same, which is stating the obvious as they simply use the microUSB port on an Android device to deliver video.
Like HDMI, SlimPort and MHL support both video and audio, with up to eight channels of surround sound available. Both normally require breakout boxes: a small dongle between your device and TV that converts the signal from your phone to one compatible with HDMI. Expect to pay between £10 and £25 for either a SlimPort or MHL signal converter. That makes things a little more expensive than using a tablet with an HDMI port, but MHL in particular is supported by a wide range of phone and tablet makers.
MHL has undergone various versions: we’re currently on version three, which improves the maximum resolution to 4K. This is the same as SlimPort, and means both standards offer pretty similar technical specs. One advantage that MHL has is support from various TV manufacturers: look on the back of your TV, and if the HDMI port has an MHL logo above it, you can use an HDMI to micro-USB cable to connect the two - the HDMI cable will pass power to your tablet or phone, meaning no need for extra adapters or cables. Bonus.
If your TV doesn’t support MHL, or you have a SlimPort device, you’ll need an adapter. SlimPort users should expect to pay around £15, while MHL users may spend slightly less. If you’re using MHL it’s likely you’ll need an external power source: MHL 3 can draw up to 10 watts from its host device.
With SlimPort no external power supply is needed (it draws a small amount of power from your device), making setup less cluttered. Both devices need a tablet’s screen to be on, though, so breakout boxes normally come with a microUSB port so a charger can be connected.
Support for MHL and SlimPort varies enormously. With three different versions of MHL available plus SlimPort, you’ll need to check the specifications of your device before buying an adaptor. The Microsoft Surface and Samsung Galaxy Tab 3 support MHL, while the Google Nexus 5 supports SlimPort.
Apple users have a simpler time: although the iPad is, technically speaking, compatible with DisplayPort, the only way to connect it to a display is with Apple’s proprietary cables. The downside is cost: you’ll pay £40 for an HDMI adapter that connects to an iPad’s Lightning connector (a 30-pin version is available for older iPads).
Connect Android to TV: Wireless
There’s little to beat the wow factor associated with beaming video straight from a tablet to your TV. The good thing about Android is that there’s more than one way to do it. Miracast is a wireless standard that creates an ad-hoc network between two devices, typically your tablet and a set-top box which supports Miracast.
An increasing number of TVs support Miracast without the need for extra hardware. Miracast uses H.264 for video transmission, which means efficient compression and decent, full HD picture quality. Better yet, Miracast supports Digital Rights Management (DRM), which means services such as iPlayer and YouTube can be streamed to a TV. Not all services work, though – see Playing Back Video below. Android devices running Android 4.2 support Miracast.
An alternative is Google’s Chromecast. This inexpensive £30 ‘dongle’ plugs into a spare HDMI port on your TV and connects to your wireless network. Chromecast support is burgeoning, which means content from services such as iPlayer, Netflix, BT Sport and others can be played with the Chromecast dongle doing all the legwork instead of your tablet, and that’s good news for battery life.
As of July 2014, it’s possible to use Chromecast to mirror the display on your Android device, allowing you to hit play on a tablet and have (non DRM-protected) video start playing on your TV. The same goes for anything the screen can display, including apps, games and photos.
Again, Apple users have an easier but more expensive time. The iPad and iPhone don’t support any open streaming standards, so you’ll need to get hold of an Apple TV (£79). This supports AirPlay mirroring from iOS devices only, and, like Chromecast, offers various streaming services including Netflix and Sky offerings Sky Sports and Now TV. BBC’s iPlayer also supports AirPlay. Note that you can’t use Sky Go to watch Sky programmes on your TV via AirPlay.

Connect Android to TV: Making it work
Streaming video to your TV from your smartphone or tablet will depend on the setup you’ve gone for. If you’re using a physical connection, such as HDMI, MHL or SlimPort, the content on your tablet’s display will simply appear on your TV once everything’s connected.
This is straightforward but has drawbacks. For one thing, your tablet will only send a signal when its screen is on. This means battery life will be sapped quickly, so it’s likely you’ll need to plug in its charger to stop it running out of power (or going to sleep) mid-show.
If your tablet has video you’ve supplied yourself, in the shape of non-DRM files, mirroring will work fine, and the same goes for various commercial services including Netflix, ITV Player and iPlayer. Life isn’t all rosy, though. Content providers know consumers will pay extra for the convenience of streaming TV shows through their homes. Sky, for example, charges subscribers an extra £11.25 if they want to watch their Sky subscriptions in another room of their house. If you want to watch your Sky subscription on a tablet there’s no charge; in fact, you can add two mobile devices per account. Plug in an HDMI cable or attempt to use Miracast and you’ll find the limits of Sky’s generosity though: outputting Sky Go’s display to an external TV or projector is banned.
If you go wireless, Miracast is currently the best option for display mirroring, as it simply outputs the contents of your Android device’s screen wirelessly. So, as with a physical connection such as HDMI, if you load a photo onto your tablet’s display, it appears on your TV. The same goes for many apps: BBC’s iPlayer, YouTube and Vimeo are all known to work via Miracast. The drawback for Miracast is the same as with a cable connection: your tablet’s display needs to be running the whole time for it to work. That, coupled with higher demands for your device’s wireless radio (particularly if it’s streaming from the internet simultaneously) could result in precipitously lower battery life.
