This adapter is designed to connect a laptop with DisplayPort to a monitor with a DVI cable. The plug snaps to the laptop and is secure. The Monitor is automatically detected and works the same, would have a DVI output as of the laptop. Good quality, the length I do not see a problem, you can hernehmen a long monitor cable yes when needed. About other functions I can not give any information. Delivery: quick and easy; Price: much cheaper than retail. Recommended!
