*Please Note: DVI/HDMI/VGA port CANNOT be used simultaneously
This adapter Mini DisplayPort (DP) seamlessly connects Mac Book, Mac Book Pro, or Mac Book Air with a Mini DisplayPort to high definition displays with HDMI, DVI or VGA input port. Using this adapter, you no need to buy 3 separate Mini DisplayPort adapters. It not only saves your money but also solves the trouble of plugging in and out, because there is only one Mini DP in Mac notebook.
Note: You can only plug one port among three output ports at one time.
