Tripp Lite HDMI over Dual Cat5/Cat6 Extender Wall Plate Kit with Transmitter and Receiver, TAA, 3 Year Warranty (P167-000),Multicolor

the default unit is for dry wall, the plaster board is cut to pass the cables thru. I could not do this I had a solid 9" brick wall so I used a standard 2gang socket and blank. I cut a hole in the blank and screwed the hdmi to that and screwed the 2gang socket to the wall. once the cat cables were connected. and I connect my hdmi leads the picture was great and it was a 20 meter run and no addition power was required. system is expensive but does the job. I highly recommend it.

I had already bought one these for an application for a new house addition and it worked great (about a 25' run). However, the 2nd unit that I bought was to feed the output signal from an Onkyo AV receiver, through a powered HDMI splitter, into this extender to the remote TV. It does not work properly this way. If I just go from the Direct TV receiver's output, through the splitter, into this extender, and into the remote TV - it works great (same as the 1st application). Now I'm told that I need a signal booster if I want to use my Onkyo AV receiver to resolve the poor signal quality at the remote TV. Do your research before you buy.
