There were two prior reviewers disagreeing about using this as a reverse switch one input, two outputs. As delivered it will not work if the receiving devices expect the HDMI +5V voltage, because there are internal diodes that block in the reverse direction. You can short these or solder them in backwards and the switch will work fine in reverse, but use at your own risk. If you make this mod, do not use the switch in the non-reverse mode. Other than the diodes the switch is completely passive.
This is to confirm Pendragon''s claim that anyone can easily modify it to work in reverse as an OUTPUT switch, e.g. to switch output between 2 tvs or tv & projector. I''ve been using it this way for a few months without a problem. To perform the mod simply remove the back cover and short the 2 resistors by taking a U-shaped wire (e.g. paper-clip) and wedging the ends underneath each wire protruding from the resistor. Do this for both resistors. It''s very easy. If you''re not careful the resistors may crack (as did mine) but that doesn''t matter since you''re just replacing them with a wire anyway. Of course only 1 output is active at at a time (i.e. its an output switch, not a splitter). Good luck!
