I'm attempting TV screen mirroring via cable and a Samsung Micro USB 11Pin MHL 2.0 to HDMI Adapter. I've swapped this out with a cable connection I normally use to mirror my MacBook Pro so I know it normally works that much.
I've tried the MHL to HDMI unpowered and powered but the Note 3 finds no TV.
Yes I know you can do it with Android File Transfer. First remove Kies altogether.
