Works great as a replacement to a 3-in1, where I was ONLY using the DVI for the connection.
Works just as good as the Apple version at a fraction of the price.
Exactly what it says it is and works perfectly:) .
Had a display with only a DVI connector and this worked perfectly to add to my laptop using its display port.
I was ready to test every combination of cable/adapter/monitor, but didn't need to after plugging in the rocketfish to my mac.
But I swapped in my girlfriend's Mac, and it didn't work there, I tried another monitor, and that didn't work, and eventually brought it into work, and swapped it in with a functional adapter, and that didn't work either.
At first my Surface would not detect my second monitor at all and the primary was shaky as well had issues with display quality from both adapters had to keep re-seating the DVI cable then not touching or moving it for it to work.
I purchased two other adapters after a few weeks and have not had any issues with the new ones from CDW.
