The LOOPS® audio and video distribution HDMI cable splitter boxes come with either 1 or 2 input ports. Connect the input HD device such as sky hd or a blu-ray player to the splitter box, then connect up to 2, 4, or 8 HDMI enabled output devices (TVs) to the splitter box and it will show the film/programme on 2, 4 or 8 screens simultaneously (model dependent) allowing you to watch on multiple TVs, which could be in 8 different rooms!.
More than one HDMI distribution amplifier splitter box can be connected together (daisy chained/cascaded) to distribute to even more HD displays at once.
