It was tested on a MacBook Pro (2010) with DVI and DisplayPort so far and the result is impeccable.
In the product description here on A. However, one does not find what times expressly says on the box two: namely, the only one of the three outputs can be used simultaneously. Who wants to drive multiple screens thus needs a signal Doppler for each method of connection.
Otherwise, for the price a very good choice (as opposed to the expensive Apple Single adapters for example).
