The Etekcity Hdmi Extender extends your HDMI signal with zero signal loss over long distances by sending the signal over a single CAT5e or CAT6 cable.
Most HDMI over CAT5e/6 cable extenders require you to use 2 CAT5e/6 cables. This can be burdensome especially if you already have a single pre-existing cable already run through your walls. If that is the case then you can just use this single UTP cable extender and not have to deal with the 2 cable setup.
