I just received my new HTC MLH to HDMI adapter for my EVO 3d, and out of the package, I get putts, nothing, notta. Is this just a issue with the new cable. Thank in advance.
Do you have your phone charger plugged into the MHL adapter while you're trying to use it? It has to be powered...unfortunately, doesn't appear that you can get away with using it without a charger.
Also, it cannot be from a usb cable plugged into a computer. It has to be plugged into an outlet. It should be charging your phone when you plug in the MHL adapter.
I just picked one up from a Tmobile store today and it works.
