As an FYI on wireless HDMI, there are 2 main types. WirelessHD operates at 60GHz and is usually the cheapest but it will not transmit through cabinets. A person standing between the transmitter and receiver will also block the signal. WHDI devices do much better in non line of sight operation. It is a little bit more expensive but reliable. There are few other types but they have no caught on yet (usually for good reason). I needed to get HDMI from my media cabinet to the bedroom TV in our slide-out. I used IOGEAR Wireless HD 3D Digital Kit

It works like a charm. It also allows our remotes to control the equipment in the media cabinet from the bedroom (via an IR repeater over the WHDI). I also added a 2x4 HDMI matrix so I can switch my satellite or media streamer to any or all TVs in the RV (the 29.3 has 3 TVs).
