How to Connect Samsung Galaxy S3 to TV

You can connect your Samsung Galaxy S3 smartphone to your TV and watch videos on a bigger screen. Just follow these steps.

1. You’ll need to purchase the Samsung Galaxy S3 HDTV Adapter. Samsung changed the configuration of the USB port on the S3, so it’s important that you purchase the Samsung branded adapter. Third-party MHL adapters may not work.

2. Once you have the adapter, simply plug it into the USB port on the phone. You can then connect a standard HDMI cable between the adapter and TV set.

3. Connect the power cable that was supplied with your phone to the adapter and plug it into a power outlet. This step is very important and often the reason why people have trouble getting this configuration to work.

4. Now that everything is connected, your TV screen will mirror what is on the phone. Audio will be routed to the TV as well. Now you’re ready to enjoy using your smartphone as an entertainment hub.

    Third-party MHL adapters DO work. I bought one off eBay for £3, plugged it in to my phone, and low and behold, it works fine.

    Andy, the TV must be a Samsung SmartTV to work with the other Samsung products. I was sure to ask the store reps before even buying. I think that may be your issue.

    Will this adapter also work with the UK version Samsung Galaxy Note GT-N7000 running ICS 4.0.3, ie. will it mirror the Note’s homescreen & desktop fully, including HD video and audio?
