How do I get the 15m optinal one invisible connect cable to connect to my frame. I want to use the cable to connect through the wall so I don't have a cable on the side of the TV. Cable will be run in the adjoining room, then returned to a suitable place and then connected to the connect box, which in turn will be in the same room on top of the kitchen cabinet where the TV is mounted. Thank you for your answer as soon as possible.
