`HOW-TO
`How to Connect Your HDTV and Smartphone With MHL

`
`Are you wondering what it means to own a smartphone, tablet, or HDTV that's MHL-certified?
`Here's how MHL works, and how it can benefit you.
`
`Back in 2009, Silicon Image developed a prototype mobile audiovisual
`interface called Mobile High-Definition Link to output high-definition content
`from a smartphone to a HDTV. A year later, Nokia, Samsung, Silicon
`Image, Sony, and Toshiba announced the MHL Consortium, a group
`developed to oversee the licensing and promotion of the specification.
`
`MHL is an audiovisual interface standard for connecting a mobile device to
`HDTVs and other displays using a single cable that
`charges the device while providing up to 1080p video
`and digital audio, all at once. Since that cable employs

`
`the common Micro-USB specification, you don't need
`fancy or particularly expensive equipment to take
`advantage of MHL; if your phone or tablet supports MHL,
`it will plug right into your HDTV or other compatible viewing device via HDMI
`on the other side of the connection. Displaying HD audio and video through
`MHL doesn't even use all of the available pins on the cable, so the cable has
`room to transmit power as well.

`
`That feature is important, because if you're going to use your phone to play
`high-definition video on your big screen, you're going to need a lot of power.
`After all, it's no secret why your smartphone battery sucks--it's that big,
`beautiful phone screen. Most phones today will encounter battery issues
`while pushing a 1080p movie to a massive HDTV; however, with an MHL
`cable charging the phone or tablet while it's playing, you'll have a juiced-up
`device that's ready for mobile use when you’re done watching the latest
`Hollywood blockbuster.

`
`All MHL-ready HDTVs also include provisions to allow users to control
`connected mobile devices with the HDTV remote via CEC (Consumer
`Electronics Control) technology, which uses the HDMI connection to send
`commands to compatible smartphones and tablets.
`
`More and more MHL-compatible devices are coming out every year, and
`chances are good that you already own an MHL-compatible smartphone or
`HDTV. LG, Samsung, and Toshiba all offer MHL-ready devices among their
`high-quality HDTV lines. You can find a ton of MHL-compatible smartphones
`and tablets, too. HTC, Huawei, Lenovo, LG, Meizu, Motorola, Pantech,
`Samsung, Sony--almost every major player in the mobile arena (save Apple)
`sells a product that is MHL-compatible.
`
`And thankfully, setting up an MHL connection in your home theater is easy.
`The first step, naturally, is to buy an MHL-compatible smartphone or tablet;
`for our testing we used a Samsung Galaxy Nexus, along with a
`Westinghouse 37-inch 1080p HDTV. The television we used is not MHL-
`compliant, but that fact actually made it a perfect choice for our
`demonstration, because it helps to illustrate how easy it is to get this system
`up and running even when you don't happen to own two MHL-compliant
`devices.
`
`Next you'll need to pick up an MHL cable that works with your mobile device
`and HDTV. This step is really simple if you happen to own devices from the
`same manufacturer (a Samsung Galaxy Nexus and a Samsung 55D7000
`HDTV, for example), because you can buy an MHL cable direct from the
`manufacturer. Otherwise you'll need to buy a generic MHL cable that works
`with your smartphone or tablet. For our tests we bought the Samsung MHL-
`to-HDMI adapter, which will set you back about $17.
`
`Here's a Samsung Galaxy Nexus alongside a Samsung MHL-to-HDMI adapter cable.

`
`Next you'll need to obtain a good HDMI cable that can comfortably stretch
`from your HDTV to your mobile device. HDMI cables are a dime a dozen
`these days, and thanks to PCWorld Labs testing we know that expensive
`HDMI cables are a poor value unless you need to cover some serious
`distance. Buy some good cables that will last, but don't pay an arm and a leg
`for the privilege.
`
`Now, if you have an MHL-compliant HDTV, plug your smartphone or tablet
`directly into your HDTV via the MHL cable, and you should be all set to start
`outputting high-definition video right from your mobile device. If you don’t own
`an MHL-compliant television, you need to take one additional step: After
`plugging your MHL-to-HDMI adapter cable into your HDTV's HDMI port as
`well as into the Micro-USB port on your mobile device, go ahead and plug a
`Micro-USB charger (which should have come with your smartphone or tablet)
`directly into the Micro-USB port on the adapter cable itself. This arrangement
`will allow you to output video from your device to your HDTV as usual, while
`also charging your device at the same time.
`
`And that's it! The MHL system is completely plug-and-play: Your device will
`flip to landscape mode when it’s plugged in, and it will push the desktop
`display to your television. It’s important to note that when you're using an
`Android device on your HDTV, you will see only the mobile versions of
`websites, and you will have to navigate via the phone’s screen. However, you
`can use a Bluetooth keyboard and mouse to navigate, and basically turn your
`smartphone or tablet into an impromptu PC.

`
`With MHL you can charge your phone and use it to surf the Web on your HDTV at the same time.
`
`The best thing about MHL technology is that it’s coming to many more things
`than just televisions. Companies such as Pioneer have developed in-dash
`receivers that work with Android devices via MHL (the product also works
`with iPhones via a different adapter) to allow hands-free calls and access to
`compatible apps via a large multitouch screen built into your vehicle’s dash.
`Roku has also joined the MHL revolution with its new Streaming Stick, a
`replacement for the normal Roku “puck” set-top box. This item works only
`with MHL-compatible televisions right now, but as more such devices are
`released, it won’t be long before something as small as a USB stick can
`replace every set-top box you have.
`
`Even though it's still nascent technology, the future of MHL seems exciting.
`Do you already have an MHL-compliant device? Do you intend to get one?
