I bought a long time ago this switch to connect to my Epson Beamer my Technisat receiver and my Panasonic Blueray. From the switch to the projector I have a 15m long cable laid. At first I had problems with dropped frames. Having examined the switch accurately, I had to realize that the contacts of the output jack dirty / were dark. After a careful cleaning of the socket with alcohol, the device now works correctly. Image transfer from Blueray I do with 1080p (FullHD)
