If you're tired of watching videos or looking at photos on the small screen of your Samsung Galaxy S3, you can easily connect this smartphone to your HDMI-enabled digital TV. To see your phone's images on the big screen, you simply need an adapter with a power cord and an HDMI cable.
Gather Your Supplies
To get started, you need an adapter than can convert the phone's MHL (mobile high-definition link) signal into an HDMI (High-Definition Multimedia Interface) signal that can be read by the TV. This type of adapter is typically called an MHL/HDMI adapter. To ensure the connection works, you should use a Samsung-brand adapter, but in some cases, generic adapters may work just as well. You also need a TV with an HDMI port and an HDMI cable.
Connect the Samsung Galaxy S3 to the TV Using the Adapter
To connect the phone to the TV using the adapter, insert one end of your HDMI cable into an HDMI port on your TV and the other end into the HDMI port on the adapter. A cable with a micro-USB plug extends from the adapter; insert this plug into the micro-USB port on your Samsung Galaxy 3S smartphone.
Provide Power to the Adapter
Now, the phone is connected to the TV, but in order to transmit videos or images, you need to give the adapter power. In addition to the micro-USB plug on the adapter, there is also a micro-USB port. To provide power to the adapter, insert one end of the adapter's power cord into the micro-USB port, and plug the other end into a wall outlet. If your adapter did not come with a power cord, you can use any micro-USB smartphone charger to provide power to the adapter.
Play Videos or Look at Images
Now that all of your components are connected, you are ready to start watching videos or looking at images. Use your phone as you normally would; open your Netflix app, tap into Hulu, or bring up your personal photographs for a fun slideshow. To make your HDMI-enabled TV work with the adapter, you may need to hit the input button on the remote control until it shows info received through the HDMI port. For example, if your TV has a cable port, two HDMI ports, and a few other ports, you need to select the HDMI port into which your adapter is plugged.
Enjoy Images on the Big Screen
The images you see on your small phone screen are now mirrored on your TV screen, and you are able to view them on either screen. The sound, however, is not mirrored. Instead, it's routed to the TV through the cords, and it plays only through your TV speakers.
