I am in the middle of building a projector setup for my father-in-law. He has a DLP that just went out, so all connections for the equipment are at the front of the room (under where the screen will be). I need to take the video signal from the front of the room and transmit it to the project ~12ft. away. I would like HDMI to be the input/output connection. I have googled it, but there are so many out there that all appear to function the same with a wide price range. Any help would be appreciated.
