Android and iOS device users have an arsenal of devices and wireless options to connect a phone or tablet to a TV. In this guide, we’re going to show you how to link up your phone or tablet to your TV via USB.
Android – Using a USB Cable
For Android devices, a USB cable can help you connect your phone or tablet to your TV, provided it has a USB port. If you’re connecting to a smart TV, go to Source>USB to enable file transfers, instead of just charging the phone or tablet via the TV.
This method is used when you want to view files or photos on a compatible TV as it technically transfers your files for opening on your TV.
Connect With An Adapter Or Cable
This method works when you want to mirror your screen onto your TV to transmit the display on-screen. You can use an HDMI adapter or cable to connect your phone to a TV and mirror the content on your screen.
A USB to HDMI adapter is the easiest option as you simply plug the adapter to your phone and plug the HDMI cable into it to connect to your TV and watch from your phone. Check that your phone supports HDMI Alt Mode, which lets it output video.
Some Android devices have micro or mini HDMI ports for direct connection to HDMI over a single cable, so it’s important to check whether your cable is compatible before connecting your devices.
Connect With a Converter
A converter allows you to mirror your phone’s screen to your TV while charging its battery at the same time. This method involves plugging the converter into a USB-C port and HDMI port using your charger and HDMI cable, and your screen will be cast onto your TV for as long as you want.
Connect Using MHL
The Mobile High-Definition Link protocol allows compatible smartphones or tablets to connect to a TV. The general setup for using MHL to connect your phone or tablet to a TV via USB requires you to have an MHL-enabled and compatible phone or tablet, HDMI and power cable, USB to HDMI MHL cable or adapter, and a display with HDMI input.
If your phone supports MHL, connect it to the HDMI MHL adapter and attach an HDMI cable, and then connect to your TV. Don’t worry about your phone or tablet battery running out of juice, because this kind of adapter has a charging port so your device can charge while you watch.
Connect Using SlimPort
MHL is one of the best ways of connecting your phone or tablet to your TV via USB, but you can also use a SlimPort cable, which works similar to MHL as it serves content from your device to your TV display except its outputs are different.
MHL and SlimPort are both plug-and-play, but MHL is limited to HDMI video output, whereas SlimPort works via HDMI, VGA, DisplayPort and DVI. This means you can use it for various displays, including older TVs that don’t have digital inputs, but have VGA.
SlimPort and MHL also differ in power supply; the former doesn’t draw power from your device, while the latter does, which is why you need to connect a power cable with the MHL method.
To use SlimPort, you’ll need a compatible device, SlimPort adapter or cable (depending on your device), display with HDMI, VGA, DisplayPort and DVI input, plus a video cable.
Plug the SlimPort adapter to your phone, and attach it to your TV using the right cable and you can view your screen on your TV.
Stream With a DLNA App
If using cables doesn’t work for you, use a DLNA app to connect your phone or tablet to your TV.
DLNA is a streaming protocol supported by most internet-connected TVs through which you can stream media files to your TV from your phone or tablet, provided the files don’t have DRM features.
Some good DLNA apps you can use include LocalCasts, which is free, or AllCast and stream your media files to a DLNA device.
Connect With Samsung DeX
DeX connectivity works with Samsung S8 or newer flagship handsets, and the Samsung Galaxy Tab S4. However, for S8, Note 8, S9 and S9+, you need a dock, power cable to charge the phone and dock, HDMI cable, and a TV with an HDMI input to use DeX connectivity.
Other Samsung devices like the Note 9 and Galaxy Tab S4 or newer models merely require a Type C to HDMI cable to enter DeX mode and DeX desktop mode respectively.
iOS – Using a Lightning Cable
This process is similar to connecting your Android phone or tablet to TV via USB, except you’ll need a Lightning cable, which differs with your iPhone model.
Most people have an iPhone 5 or newer with a Lightning connector, but for HDMI outputs or VGA connections, you need a Lightning digital AV adapter or a Lightning to VGA adapter respectively.
For iPads, all models use the Lightning cable for iOS to TV connections, except the iPad 3 and older use the 30-pin cable, but you’ll pick either a digital AV or VGA adapter depending on your display’s input.
There are many third-party cables but most of them don’t work if you want to watch video-streaming services like Netflix or Hulu, or on-demand video like DirecTV or Comcast Xfinity. They lack HDCP (High-bandwidth Digital Content Protection), which protects against pirates capturing the content.
Plug in the adapter and connect video output to your TV and your screen will mirror to the display. Remember to plug the USB end of the cable into the adapter and the other end to a power source, as it needs to be charged to play.
Note: The Digital AV Adapter for iOS devices comes in two models, serving different purposes. One connects your iPhone or iPad to a TV with HDMI output, while the VGA adapter plugs into VGA-compatible peripherals, so be sure to pick the right version.
Connect With a DLNA App
Like Android, you can connect your iOS device to internet-enabled TV using DLNA apps to stream media such as videos or music. For videos and music purchased from iTunes Store, you won’t be able to use a DLNA app to stream content with DRM restrictions.
The good thing about using a DLNA app is that it’ll still find media on other devices like your computer and set up streaming to your game console, TV, or another PC without having to convert a video or install special codecs for it to work.
