The HTC One can be connected to your TV. Doing so gives you the ability to view your mobile contents or even play games on your HTC One, mirrored to your HD TV.
Connect HTC One To TV
1. Obtain an optional Media Link HD (MHL) adapter.
2. Connect your HTC One to a TV with the optional Media Link HD (MHL) adapter.
3. Connect your adapter from your HTC One data port, into your TV’s HDMI port.
4. Now, change the TV input to the adapter input.
Once completed, your TV instantly displays what’s on your HTC One screen.
Hint: The Media Link HD adapter comes with a casing which should allow you mount it to the back of your TV. Other options can be to just let it hang off the back on entertainment centre. Once booted, your HTC should detect it.
This is how you connect HTC One to Tv. I hope this was helpful, if it was let me hear your experiences.
