The GGM HDEXT2K50M is a kit comprising an emitter which converts a signal coming from an HDMI source into a network RJ45 cable, as well as a receiver which converts the signal from the network cable into HDMI in order for it to go towards a display, monitor or screen. The receiver is powered via the PoE network cable and has therefore no need of a bulky power supply. These are Plug and Play products requiring no installation configuration. Furthermore, in the rare case where pairing is difficult, the EDID configuration simplifies the procedure. The emitter has a “loop out” HDMI output in order to display the source contents on a local screen.
