After the low price I had drawn, I had to find at home that the cable did not want to with all my equipment. It was thought the cable to connect my AV receiver (Pioneer VSX-520-K) to use with my projector (Acer H7531D), which was not possible. Even between PS3 and Beamer I managed no transmission. Curiously, a connection between PS3 / PC and Sony television possible, the transmission quality is satisfactory.
On request from the manufacturer I could not be helped. A return was offered, but only at his own expense, which I think is not Mimics the standard of service today. I have now bought another cable, with which everything works fine.
