First I have to praise the seller's service. My first cable has gone quite fast break, then I called the support and was helped immediately, a new cable came in exchange. That was within two days, as fast as I've rarely experienced! Well, now to the cable. The second is now also in use and performs its tasks reliably, I have a 23 "Eizo monitor to work and connects immediately without hesitation with my little Mac Air, since I use the cable almost every day, is something preprogrammed load and contrary to all fears over cheap products, the Canaan cable makes really good. That made me then so convinced that I have already ordered a second, for home / living room at times occasionally to watch a movie and the connection to the monitor is immediately without ceremony, even in Full HD.
