The cable does not transmit the image from my MacBook to TV very good but unfortunately the sound! Coming out of the MacBook. Important: The cable must be plugged only in the notebook and are then connected to the TV, otherwise the connection does not go with me. To the TV as a large work screen to use 1A - watch the movies, well - because the sound through the notebook comes. If someone has a tip on how to get the sound through the TV, I would be very grateful!
