I have 1 622 and use hdmi to main tv. I ran 75ft component to bedroom hd and I want to send 25 ft component to a 3rd hd which will never be used at the same time as the 2nd. I found a switch at walmart that has 4 inputs and 1 output. I need 1 input and 2 outputs to run the 622 component output to 2nd and 3rd hdtv's. Do these switches work in reverse. Any suggestions? Thanks for the help.
