Connecting an HDTV monitor over Ethernet allows you to view HD video from your computer even if that computer doesn’t have an HDMI display output. In addition, by sending HDMI signals over Ethernet you can make your monitor a sharable network resource, enabling all the devices on a network to use it as a display when needed. In order to connect an HDMI display to a computer or network over Ethernet you need a HDMI over IP extender. Extenders act as an interface between an HD display and a network, allowing networked devices to communicate with the display directly. Writer Bio
