Used to provide images with a Freebox on both an HD flat screen (and sound on the Hi Fi) and a pico-projector prefer when the movie version while keeping the sound Hi Fi. Super simple connection, no image defect on one or the other exits. Not Rated longer time before seeing the picture (except for the very first time you plug the cable: it takes him 2-3 sec.). This true and that the diodes are very powerful (I shot).
