So this is the challenge for Monster: How do we increase our cable sales?
Answer: Tell everyone it is a wireless solution. Not only do you sell them the box, but you also force people to buy another cable for the connection.
Whereas, before you simply connected the reciever to the video monitor/projector with a single cable. You now get to connect the receiver to wireless box A with a cable, and then purchase a second cable to connect the video monitor/projector to wireless box B. Shear marketing genius!
