The first time I saw the flat cable by In-Akustik in an edition of Audio Vision. There has been very well tested (even when transmitting 3D and 4K signals). I even need it at present exclusively for the transmission of normal 1080p signals (2D BR discs, from Denon AVR Epson Full HD Projector). This works perfectly, no failures in picture and sound, everything toppfit. In addition, I am still prepared for the future, should it me in the years to come on time, in terms of hardware upgrade to 4K. The installation is very simple, because the cable is very flexible. In curves, the cable must be naturally stored upright.
Strong buy recommendation. The price (about 50 Euros) is for the length übigens also ok, if you take it apart, that there are low-budget cable in 15 meters for less than 20.- Euro.
